MUSTANG™ MICRO PLUS
GUITAR HEADPHONE AMP
OWNER’S MANUAL
INTRODUCTION
This manual is a guide to the features and functions of Mustang Micro Plus—a
plug-and-play headphone amplifier and interface that connects directly to your
guitar and bass to deliver amp models, effects models, Bluetooth streaming and
more. With fantastic Fender Mustang amplifier sound and yet no larger than a
deck of cards, Mustang Micro Plus is easily portable and provides up to six
hours of battery-operated playing time.
Mustang Micro Plus is simple and intuitive. Connect it to any popular
instrument model using the 1/4” rotating input plug. With 25 great-sounding
Mustang amplifier models, 25 effect models in moveable blocks and remote
editing using the Fender TONE™ app, players can choose among 100 onboard
presets (70 factory presets and 30 empty presets ready for personalized
customization) and access cloud presets. Turn Bluetooth on and stream music to
play along with, or play to online sources with synced audio and video. The
display window conveniently shows the preset in use, onboard tuner and other
functions, and the USB-C port enables easy audio recording and firmware
updates. With remarkably compact sound, style and versatility, Mustang Micro
Plus delivers it all straight to your earbuds, headphones or digital recording
software.

INSTRUMENT CONNECTION AND POWERING UP
Connecting Mustang Micro Plus to your guitar couldn’t be easier—simply rotate
the 1/4” input plug out from the unit and plug it into the guitar’s input
jack.
Slide the power switch to the center ON position; the power LED will
illuminate green for 10 seconds and then extinguish, indicating that Mustang
Micro Plus is on and charged (different LED colors indicate different charging
status; see page 8). You’re now ready to choose or create a preset with an amp
model and a selection of effects, adjust volume and EQ, tune up, engage
Bluetooth, and start playing.
If power is on but no instrument input is detected for 15 minutes, Mustang
Micro Plus will automatically switch to a low-power sleep mode; press any
button to wake it up. Slide the power switch to OFF to power down.
WARNING: Connecting Mustang Micro Plus to your instrument, disconnecting it or touching the end of the device’s plug may cause a loud noise. To avoid hearing damage when wearing heaphones/earbuds, follow these steps to ensure safe operation of your device:
- When connecting/disconnecting Mustang Micro Plus, remove headphones/earbuds, ensure that the device is turned off, or ensure that the device’s MASTER VOLUME control is set to zero.
- Turn the device on with MASTER VOLUME set to zero, then gradually adjust volume to reach a comfortable listening level.
When wearing headphones/earbuds, connecting/disconnecting Mustang Micro Plus or touching its exposed plug while unit is on and MASTER VOLUME is up is similar to plugging an instrument cable into a live amplifier with volume up or to touching the exposed end of a live instrument cable.
BLOCKS
All Mustang Micro Plus presets contain five “blocks” for creating an entire
signal path from input to output—one amplifier block and four effects blocks.
There are 25 amplifier models, each paired with a default cabinet model, and
25 onboard effect models organized into four categories: stompbox (11),
modulation (6), delay (4) and reverb (4).
The amp block contains an amplifier model paired with a fixed speaker cabinet
model. Basic amp settings can be adjusted, while more advanced settings such
as noise gate, gate position, sag, tube bias, etc. are fixed. The amp block is
stationary, with its default position at the center of the signal path.
Each preset has four effect blocks, one for each effect category—stompbox,
modulation, delay and reverb. Effect blocks are moveable and can be placed
before or after the amp block using the Fender TONE app.

the next power-up.
TAP TEMPO
Press the TAP BUTTON twice or more to set a tempo (in BPM) for a delay
effect. The BPM designation and a flashing circle will appear in the DISPLAY
WINDOW during adjustment. The TAP BUTTON displays the current tempo on the
first button press, which counts towards the two-tap minimum to change the
tempo:
TUNER
Press and hold the TAP BUTTON for two seconds to activate the TUNER; the
target note and indicator needle will appear in the DISPLAY WINDOW. The
indicator needle shows degrees of sharpness and flatness until the correct

MODIFY
Tap the MODIFY BUTTONS to adjust a single parameter of an assigned modulation,
reverb or delay effect (i.e., delay level, reverb level, modulation rate, et.
al). The block category, parameter name and parameter value will appear in the
DISPLAY WINDOW. Note that the minimum and maximum control limits of the MODIFY
buttons will vary according to the effect parameter assiged, and will default
to the saved preset value.
The MODIFY parameter is assignable per preset using the Fender TONE app. In
the app, navigate to the preferred effect and single-touch any parameter to
get an onscreen gradient that can be used for more precise adjustments.
Touch and hold any parameter for two seconds to initiate MODIFY control
assignment and follow the onscreen prompts. The assigned MODIFY parameter will
be indicated by a white ring around the parameter control:
PRESET
Mustang Micro Plus has 70 factory presets and 30 empty slots for user-created
presets. Pressing the PRESET BUTTONS will wake the display screen and show the
current preset name and number. Subsequently, a single press to either button
will move up or down to the next preset; pressing and holding either button
will scroll up or down with acceleration.
SAVE
When a preset has been edited from the saved state, the preset number inverts
from white text on black to black text in a white box. Only changes made to
effect parameters and tap BPM are saved on Mustang Micro Plus; preset name,
location and other preset parameters are editable using the Fender TONE app.
To save a preset edit, press and hold the SAVE BUTTON for two seconds to
initiate the save prompt. Display will wake and display SAVE PRESET?

BLUETOOTH
Mustang Micro Plus easily streams Bluetooth audio, so you can play along in your headphones or earbuds. The device is discoverable as “Mustang Micro Plus” on smart phones and other Bluetooth devices.
To activate Bluetooth pairing mode, push the POWER switch to the far left and
hold it there for two seconds. The POWER switch Bluetooth position is spring-
loaded for momentary contact only, and will return to the center “ON” position
when released. In pairing mode, the POWER LED will flash blue for two minutes
or until a connection is established.
On successful connection, the POWER LED will turn solid blue for 10 seconds
and then extinguish.
To disconnect a Bluetooth device from Mustang Micro Plus, hold the POWER
switch in the Bluetooth position for two seconds and then release it (as when

to pairing mode with a flashing blue LED; pairing mode will expire within two
minutes if no other Bluetooth connection is made, and the blue LED will
extinguish. Alternately, disconnect using theexternal device.
Mustang Micro Plus automatically pairs with the last connected Bluetooth
device if that device is available. Note that MASTER VOLUME controls
instrument and overall volume only; the mix between an instrument and a
Bluetooth audio source is determined using the volume control on the external
device.
