EDITING AND SAVING PRESETS
Presets can be easily edited and, if desired, renamed and saved in place or saved in a different location. The controls of each amplifier type can be adjusted, or an amp model can be replaced with a different one. Similarly, various effects controls can be adjusted, or effects can be removed from or added to a preset. When a preset is active, the box containing its number is blue, indicating that no edits have been made. Once an edit is made, the box containing the preset number turns red and the preset title screen will read “UNSAVED”. When edits are saved, the preset number box returns to blue and the “UNSAVED” title clears.

ACCESSING PRESET CONTENTS
To access the contents of a preset, press the ENCODER. From the top down, the DISPLAY WINDOW will then show the number and name of the preset, the amplifier type in use, and four boxes that organize the effects used for that preset (if any). These effects category boxes are labelled STOMP (stompbox), MOD (modulation), DELAY and REV (reverb). When first accessing preset contents, the preset name and amplifier type are highlighted in blue: Select the amp model or one of the effects category boxes by turning and pressing the ENCODER. The active selection is then highlighted in blue:

EDITING AND SAVING AMPLIFIER CONTROL SETTINGS
To edit and save individual control settings of a preset’s amplifier model, first select the amp model by pressing the ENCODER on it. The DISPLAY WINDOW will then show a list of controls for the amp model in use: There are two ways to adjust an amp control knob setting. A control parameter that corresponds to an actual physical knob on the control panel can be adjusted simply by turning the physical control knob until the desired value is reached in the DISPLAY WINDOW. In the example below, the amp model’s TREBLE setting is adjusted by turning the physical TREBLE control knob on the control panel:

Alternately, select a control parameter by turning and pressing the ENCODER; its surrounding box will turn from blue to red: The control can then be adjusted by turning the ENCODER or by turning a corresponding physical control knob on the control panel: At this point, press the ENCODER or the BACK utility button (green arrow) to accept the adjusted control values. Pressing BACK returns the user to the preset contents screen; pressing the ENCODER lets the user continue making control setting changes, and the box surrounding the control setting will return to blue. When control setting edits are complete, press the SAVE utility button to save the changes to the preset.

IMPORTANT: If edited amp control settings are not saved, the preset will revert to its original amp control settings when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save edited amp control settings, press the SAVE utility button and use the ENCODER to scroll to one of three options—SAVE, SAVE AS or REPLACE. Each is detailed below.

SAVE: Keeps an edited preset in the same location with the same name. To do this, press the SAVE utility button and use the ENCODER to scroll to “SAVE”. Press the SAVE utility button again or press the ENCODER. A brief “PRESET SAVED!” screen will then flash before returning to the original preset screen:

SAVE AS: Enables saving a preset in a different position, with or without a different name.

To do this, press the SAVE utility button and use the ENCODER to scroll to “SAVE AS”. Press the ENCODER to access a “CHOOSE SLOT” list of locations where the preset can be moved. Select a new location by turning and pressing the ENCODER: Whether renaming the preset or not when using “SAVE AS”, a name must be entered by pressing the ENCODER to activate a cursor, then spelling out the name by turning and pressing the ENCODER to scroll through and select characters. All characters can be cleared by using the ENCODER to scroll to and select “CLEAR ALL”. When name entry is completed for the new location, save it by pressing the SAVE utility button or by using the ENCODER to scroll to and select “SAVE”. A brief “PRESET SAVED!” screen will then flash before returning to  the original preset screen:

REPLACE: Any existing preset can be replaced with another by pressing the SAVE utility button, using the ENCODER to scroll to and select “REPLACE” and choose among the 30 original factories presets (page 3). After selecting “REPLACE”, use the ENCODER to scroll to any of the 30 presets; each one is automatically “previewed” so the user can hear it before the preset is loaded. Press the ENCODER to select the preset, confirm it by using the ENCODER to scroll to and select “NO CANCEL” or “YES REPLACE” (not shown) and save it in the chosen slot:

CHANGING THE AMPLIFIER MODEL IN A PRESET

The amplifier model in a preset can be replaced with another one (see list of Mustang LT50 amplifier models on page 8).

To do this, access the contents of a preset by pressing the ENCODER on it; the amp model will automatically be highlighted. Press the ENCODER again to see a list of controls for the amp model in use; the name of the amp model appears at the top of this list. Press the ENCODER once more to activate the amplifier replacement function; the box surrounding the amp name will turn from blue to red, and white arrows will bracket the amp name.

Turn the ENCODER to scroll to a new amp model.

Press the ENCODER to accept the amp model change, after which the box surrounding the amp name will return to blue; or press the BACK utility button to accept the amp model change and return to the preset contents screen:

IMPORTANT: If an amplifier replacement is not saved, the preset will revert to its original amp type when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save a preset amp replacement, follow the SAVE, SAVE AS or REPLACE instructions on page 6 and at the top of this page.

EDITING AND SAVING EFFECTS CONTROL SETTINGS
To edit and save individual control settings of a preset’s various effects (if any), first select the effect category box containing the effect to be edited by turning and pressing the ENCODER. There are four effects category boxes that can each contain one effect: STOMP (stompbox), MOD (modulation), DELAY and REV (reverb):

The DISPLAY WINDOW will then show a list of controls for the effect model in use in that category; use the ENCODER to scroll to a particular effect control. Press the ENCODER to select the effect control; it’s surrounding
the box will turn from blue to red. Turn the ENCODER to set a new value for the selected control value:

At this point, press the ENCODER to accept the adjusted effect control value and exit edit mode; the surrounding box will then return to blue. Alternately, press the BACK utility button (green arrow) to accept the effect control value change and return to the preset contents screen:

IMPORTANT : If an edited effect control setting is not saved, the preset will revert to its original effect control settings when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save edited effect control settings, follow the SAVE, SAVE AS or REPLACE instructions on pages 6 and 7.

REPLACING, ADDING AND DELETING EFFECTS

As noted, each of the four effect category boxes can contain one effect. If an effect is present, it can be replaced with another effect in that category, or it can be deleted. If no effect is present, one can be added (see list of Mustang LT50 affects models on pages 13-14). The signal path is Instrument—Stompbox—Modulation— Amplifier—Delay—Reverb—Speaker, as illustrated at left below. Note that effects category boxes that already contain an effect have a solid outline, whereas effects category boxes that do not contain an effect have a dotted outline, as seen in the image at right below:

To replace an effect, access the contents of a preset by pressing the ENCODER on it, then use the ENCODER to scroll to one of the four effect category boxes. Press the ENCODER again to see the effect contained in the effect category box; the name of the effect model is highlighted at the top of the DISPLAY WINDOW:

Press the ENCODER once more to activate the effect replacement function; the box surrounding the effect name will turn from blue to red, and white arrows will bracket the effect name. Turn the ENCODER clockwise to scroll through other effects models in that category. Press the ENCODER to accept a replacement effect and exit edit mode; the surrounding box will return to blue. Alternately, press the BACK utility button (green arrow) to accept the replacement effect and return to the preset contents screen:

To delete an effect, the steps are very similar to those on page 10. As before, access the contents of a preset by pressing the ENCODER on it, then use the ENCODER to scroll to an occupied effect category box. Press the ENCODER again to see the effect contained in the effect category box; the name of the effect model is highlighted at the top of the DISPLAY WINDOW:

Press the ENCODER once more to activate the effect replacement function; the box surrounding the effect name will turn from blue to red, and white arrows will bracket the effect name. Turn the ENCODER counterclockwise until the red- highlighted effect label at the top of the DISPLAY WINDOW reads “NONE”. Press the ENCODER on “NONE” (or press the BACK utility button), after which the user is returned to the preset screen with the previously occupied effect category box now empty:

To add an effect to an empty effect category box, first access the contents of a preset by pressing the ENCODER on it, then use the ENCODER to scroll to the empty effect category box. Press the ENCODER again to access the empty effect category box; the red-highlighted label “NONE” will appear at the top of the DISPLAY WINDOW:

Turn the ENCODER clockwise to scroll through effects models in that category. Press the ENCODER on the desired effect, after which the box surrounding the effect name will return to blue and the effect is added— although not yet saved—to that effect category box. Alternately, press the BACK utility button (green arrow) to return to the preset contents screen (see illustrations on next page):

IMPORTANT: If an effect is not saved once it has been replaced, deleted or added, the preset will revert to its original effect model(s) when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save a changed, deleted or added effect model, follow the SAVE, SAVE AS or REPLACE instructions on pages 6 and 7.

SETTING DELAY TIMES WITH THE TAP BUTTON

There are three ways to set delay times for effects in Mustang LT50’s “DELAY” effects category box. The first way is to use the “Editing and Saving Effects Control Settings” instructions found on page 9, using the ENCODER to scroll to, select and adjust individual effect settings, including delay time. The second way is to use the Mustang LT50’s TAP utility button (yellow arrow). If a preset includes a delay effect, the TAP LIGHT (green arrow) flashes in time with that effect’s default delay time. This time setting can be modified by tapping the TAP utility button two or more times at the desired tempo, regardless of what screen is shown in the DISPLAY WINDOW: The third way to set delay times is to use the four-button footswitch; see page 19 for instructions on how to do this.
IMPORTANT: If an edited delay time is not saved, the effect will revert to its original delay time when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save an edited delay
time, follow the SAVE, SAVE AS or REPLACE instructions on pages 6 and 7.

MENU FUNCTIONS

Mustang LT50 features five convenient MENU functions—TUNER, FOOTSWITCH, LEVELS, RESTORE and
ABOUT— all easily accessed by pressing the MENU utility button. The first function (TUNER) is automatically highlighted; use the ENCODER to scroll to and select any MENU function:

TUNER: Enables the use of Mustang LT50’s built-in chromatic tuner (page 16).
FOOTSWITCH: For configuring the quick-access preset, effects on/off and tuner functions of Mustang LT50’s optional four-button footswitch (page 17).
LEVELS: Level control with a signal-strength meter for use when recording using the USB audio port on the control panel, or when using the rear-panel mono line output to send a signal to external sound and recording equipment (page 21).
RESTORE: Enables restoration of factory presets and amplifier settings (page 21).
ABOUT: Displays the amp’s current firmware version (page 22).

MENU FUNCTION: TUNER

There are three ways to access the Mustang LT50’s built-in chromatic tuner. The first way is to press and hold the TAP the utility button on the control panel until the tuner screen appears in the DISPLAY WINDOW:

The second way is to press the MENU utility button on the control panel; the list of MENU functions will appear in the DISPLAY WINDOW with the TUNER function automatically highlighted atop the list.

ENCODER on TUNER to access the tuner screen
To use the TUNER, sound a note; the letter name of the pitch will appear in the box at the bottom and the shorter vertical bars on either side of the longer vertical centre bar will illuminate red to indicate varying degrees of sharpness (to the right) or flatness (to the left). When a pitch is precisely in tune, the longer vertical centre bar and the two shorter vertical bars on either side of it will illuminate green: Note that speaker output is muted when tuning and that the volume control on the instrument being tuned must be turned up sufficiently to register a TUNER reading. The third way to access the tuner is by using the footswitch. To use the footswitch for hands-free chromatic tuning, see the instructions on page 20.

MENU FUNCTION: FOOTSWITCH
Connect the optional four-button MGT-4 footswitch by plugging it into the “FOOTSWITCH” jack on the rear panel; note that Mustang LT50 comes with a magnetic footswitch overlay that provides correct footswitch labelling for the MGT-4 and other compatible four-button Fender footswitches*. The footswitch provides convenient quick-access preset selection, effects on/off switching and delays tap tempo control and a hands-free tuner function. When the footswitch is connected and the amplifier is on, the footswitch is automatically synched with the active preset, and the red “BANK 1” LED at the far left will illuminate. For example, if preset 9 (“Jazz Amp”) is active and the footswitch is connected to the amp, the footswitch will synch up with that preset, as indicated by “P09” in the footswitch’s display window:

FOOTSWITCH: QUICK ACCESS PRESETS

The four-button footswitch can be configured for hands-free switching among up to eight “quick-access” presets, arranged in two “banks” of four presets each. To do this press the MENU utility button and use the ENCODER to scroll to and select “FOOTSWITCH.” Both quick-access preset banks will appear in the DISPLAY WINDOW below the header “QUICK ACCESS”; the upper bank (“BANK 1”) is automatically highlighted in blue.

Press the ENCODER on it, and the four preset slots in the first bank appear with their default settings, labelled “A”, “B”, “C” and “D” to correspond to the “A”, “B”, “C” and “D” buttons on the footswitch. The first preset slot (“A”) will be highlighted in blue: Older Fender MS-4 and ULT-4 four-button footswitches are also compatible with Mustang LT50. The magnetic footswitch overlay that comes with Mustang LT50 fits both footswitches.

To assign a different preset to slot “A”, for example, press the ENCODER on it. A “CHOOSE SLOT” screen then appears with a numbered list of 30 presets, the first of which is highlighted in red. Use the ENCODER to scroll to and select a new preset for slot “A” (preset 18 in the example here):

The new preset now occupies preset slot “A”. Use the same steps to replace the presets in slots “B”, “C” and “D” in BANK 1 if so desired. To set four more quick-access presets, use the ENCODER to scroll to and select the second bank (“BANK 2”), then follow the same steps:

Once configured, all eight quick-access presets are easily accessible using the footswitch. When the amp is on and the footswitch is connected, BANK 1 is automatically active, and the four presets contained in it are assigned to footswitch buttons “A”, “B”, “C” and “D”. Simply step on the button corresponding to the desired preset. In the example here, preset 18 has been assigned to slot “B” in BANK 1 (as indicated by the illuminated red BANK 1 LED at far left, the illuminated red LED above switch “B” and in the footswitch display window); step on the footswitch button “B” to activate it (yellow arrow):

To access the presets in BANK 2, step on buttons “A” and “B” simultaneously. The green “BANK 2” LED at the far left will illuminate, indicating that the four presets in BANK 2 have been assigned to footswitch buttons “A”, “B”, “C”
and “D”. As before, step on the button corresponding to the desired preset. In the example here, preset 5 has been assigned to slot “A” in BANK 2 (as indicated by the illuminated green BANK 2 LED at far left, the illuminated red LED above switch “A” and in the footswitch display window), so step on the footswitch button “A” to activate it:

FOOTSWITCH: EFFECTS ON/OFF
Effects in a preset (if any) can be turned on and off using the footswitch. To do this, step on buttons “A” and “B” simultaneously until the amber “EFFECTS” LED illuminates at far left (see illustration below). Footswitch buttons “A”, “B”, “C” and “D” are also respectively labelled as “STOMP” (A), “MOD” (B), “DELAY” (C) and “REVERB” (D). Since one effect only from each of these four categories can appear in a preset, any effects used in a preset are automatically assigned to the four footswitch buttons.

In the example here, active preset 9 contains one stompbox effect and one reverb effect. Consequently, with the footswitch in “EFFECTS” mode, the stompbox effect is automatically assigned to footswitch button “A” and the reverb effect is automatically assigned to button “D” (the preset has no modulation or delay effects, so footswitch buttons “B” and “C” are inactive). Merely step on these buttons to turn these effects on and off:

FOOTSWITCH: TAP TEMPO FOR DELAY EFFECTS
For presets with a delay effect, the footswitch has a tap tempo function for hands-free adjustment of delay rates. To do this, first put the footswitch in BANK 1 or 2 mode as described above. Select a preset with a delay effect; step on the footswitch button corresponding to the current selected preset twice or more at the desired tempo. This changes the delay time in the same manner as tapping the TAP tempo utility button on the amp’s control panel (page 12).
IMPORTANT: If delay rate changes are not saved, the preset in use will revert to its original delay rate when returning to the preset after leaving it, or when turning the amplifier off and back on again. To save delay rate changes in a preset, follow the SAVE, SAVE AS or REPLACE instructions on pages 6 and 7.

FOOTSWITCH: TUNER
To use the footswitch for hands-free tuning, step on buttons “C” and “D” simultaneously to activate chromatic tuner mode. Note that putting the footswitch in tuner mode also activates the tuner display on the Mustang LT50 control panel (page 16). The pitch letter closest to the sounded note will appear in the footswitch display window (symbols to the right of each pitch letter denote sharp and flat notes; when tuning to, for example, C sharp or E flat). When sounding a note, the LEDs above footswitch buttons “A” and “B” illuminate red to indicate degrees of flatness; the LEDs above footswitch buttons “C” and “D” illuminate red to indicate degrees of sharpness. When the correct pitch is attained, the centre LED beneath the footswitch display window will illuminate green. When tuning is complete, step on any button to exit tuner mode. Note that the footswitch tuner uses mute speaker output.

• To activate the footswitch tuning function, step on buttons “C” and “D” simultaneously (double yellow arrow).
• In the example above, a “G” note is displayed as being particularly flat, as indicated by the illumination of the red LED above button “A” (green arrow).
• Here, the “G” note is displayed as slightly sharp, as indicated by the illumination of the red LED above button “C” (green arrow)
• Here, the “G” note is at the correct pitch, as indicated by the illumination of the green centre LED (green arrow). When tuning is complete, step on any button to exit the footswitch tuner mode.

MENU FUNCTION: LEVELS
The third MENU function—LEVELS—features a level control for use when recording using the USB port (page 23) on the control panel, and for the mono line output (page 23) when connected to external sound and recording equipment. Note that the MASTER VOLUME control does not control USB and mono line output volume. To access this option, press the MENU utility button and use the ENCODER to scroll to and select LEVELS. The
level control is automatically highlighted:

Turn the ENCODER to set a new “LEVEL” value. Press the ENCODER to accept the new value and exit the menu. Alternately, press the BACK utility button (green arrow) to accept the new value and return to the MENU function screen:

For best sound quality, set the “LEVEL” so that the signal stays within the green bars, and barely reaches the single yellow bar at the right, and does not reach the single longer red clipping bar at the far right (all bars shown illuminated in the illustration above). Note that changing presets can change individual volumes; “LEVEL” readjustment may be necessary when changing presets.

MENU FUNCTION: RESTORE

The fourth MENU function—RESTORE—enables the restoration of all original factory presets and amplifier settings. To do this, press the MENU utility button, then use the ENCODER to scroll to and select RESTORE: To initiate restoration use the ENCODER to scroll to and select “YES RESTORE”. To cancel restoration, press the ENCODER on “NO CANCEL”, or press the BACK utility button. While restoration is in progress, a blue waiting screen
with a progress bar will appear. When restoration is complete, the user is returned to the first preset screen:

MENU FUNCTION: ABOUT
The fifth MENU function—ABOUT—displays the amp’s current firmware version. To do this, press the MENU utility button, then use the ENCODER to scroll to and select ABOUT; the current firmware version will be displayed:

AUXILIARY INPUT AND HEADPHONE OUTPUT

The Mustang LT50 control panel features two 1/8”-inch jacks: an auxiliary input for connecting external mobile/audio devices and an output for convenient headphone use. Note that when using the auxiliary input, volume levels for external devices are set using volume controls on the external devices themselves (the amp’s volume controls are for overall volume level only and do not affect the individual volume of external devices connected to the auxiliary input jack). Also note that speaker output is muted when headphones are plugged in, and that the auxiliary input signal is not sent to the USB port or mono line output.

USB PORT

The Mustang LT50 control panel features a USB port for audio recording and Fender TONE use (see “FENDER TONE” below). Using a micro USB cable (not included), connect a computer with recording software to this port. No external driver is needed to connect to an Apple computer. To connect to a Windows-based computer, the user must download the ASIO driver setup with a Fender Mustang device, available at https://support.fender.com/hc/en- us/articles/214343123-How-do-I-know-which-ASIO-Driver-to-use. Note that although the USB port and the auxiliary input can be used simultaneously, the USB port cannot be used to record a signal from the auxiliary input. Also note that the USB output is in stereo and that while preset gain, volume and tone controls will affect USB level and tone, the MASTER VOLUME control does not.

When recording using the USB port, a level control is located in the LEVELS menu function (page 21). Mustang LT50 has a rear-panel 1/4” mono line output for connection to external sound and recording equipment. When using the rear- panel mono line output, a level control for it is located in the LEVELS menu function (page 21). Note that preset gain, volume and tone controls will affect mono line output level and tone; the MASTER VOLUME control does not affect mono line output level. Also, note that a TRS (stereo) cable can be used to reduce or eliminate hum.
