MENU OPTIONS – DISPLAY
MENU OPTIONS – TUNER
MODE: Change between Needle and Strobe tuning modes. Each option provides
distinct visual feedback for a variety of tuning applications.
NEEDLE MODE: The incoming pitch is tracked on the tuning strip at the top
of the display. When an incoming note is flat, the indicator will appear on
the left of the center of the tuning strip and turn red. When an incoming note
is sharp, the indicator will appear on the right of the center of the tuning
strip and turn red. When you are in tune, the indicator is centered with the
arrows on the tuning strip and the indicator will light up green.
STROBE MODE: The incoming pitch is tracked by the rotational speed and
direction of the tuning wheel around the target note.
When an incoming note is flat, the tuning wheel will rotate counterclockwise.
When an incoming note is sharp, the tuning wheel will rotate clockwise.
The more flat or sharp the incoming note is, the faster the tuning wheel will
spin in the respective direction. As the note becomes more in tune, the
rotational speed of the tuning wheel decreases.
When the wheel stops rotating, the incoming note is in tune.
NOTE: the strobe algorithm is a direct connection to the pitch of the incoming note. Since the pitch is always moving slightly, the tuning wheel will never stop for long if at all. Tune until it is as still as you can make it for hyper-accurate tuning.
CHROMATIC: Tracks and detects the full frequency range of the guitar
signal.
GUITAR STD: Tracks and detects frequencies only in the standard EADGBE
guitar tuning range. When an incoming note is outside of the tuning preset
range, the note will not be tracked.
DROP D: Tracks and detects frequencies only in the standard DADGBE guitar
tuning range. When an incoming note is outside of the tuning preset range, the
note will not be tracked.
BASS STD: Tracks and detects frequencies only in the standard EADG
4-string bass guitar tuning range. This tuning mode also supports the lower B
string and higher C string included in 5 and 6-string bases. When an incoming
note is outside of the tuning preset range, the note will not be tracked.
TUNING PRESET: Select pitch ranges that the tuner will display and
detect.
TRANSPOSE: Transpose the tuning presets to suit your guitar’s drop or
capo tuning. The tuning preset can be transposed up to Capo 5 (+5 semitones)
and down to Drop 6 (-6 semitones). Ex. The GTR STD preset will be set to tune
to DGCFAD when transposed to Drop 2.
REFERENCE PITCH: Modify the tonal center that the tuner uses. By default,
the tuner is set to the widely adopted standard of 440Hz. This is the
frequency that the A key above Middle C on a piano is tuned to. The center
pitch can be lowered down to 390Hz and raised up to 490Hz.
IN-TUNE THRESHOLD: Modify the window the tuner uses to determine if you
are in tune in cents. In Needle Mode, the In-tune Threshold affects how close
the indicator has to be to the tuning strip center before it turns green to
tell you you’re in tune. In Strobe Mode, the In-tune Threshold affects the
rotational speed as you approach the note you’re tuning to. A lower threshold
value will be more precise with your tuning while a higher threshold value
will provide faster visual feedback.

TUNE ASSIST
TUNE ASSIST
Activating Tune Assist provides additional visual feedback for a more efface tuning experience. When activated, the Canvas Tuner will track how long a note stays within the In Tune Threshold window. When a note has successfully been detected within the in-tune window for the defined time, a border will flash around the display to let you know you’re in tune and can move to the next string. Choose between Slow, Medium, Fast, and Instant thresholds to select how long the incoming note has to stay within the in-tune window before Tune Assist indicates you’re in tune.
MENU OPTIONS – BYPASS MODES
Modify the signal bypass and muting behavior of the Canvas Tuner.
BUFFERED BYPASS: When the pedal is bypassed, the incoming audio signal is
routed through our clean low-noise buffer. When the tuner is active, the
incoming signal is muted and the tuner is displayed.
RELAY BYPASS: When the pedal is bypassed, the incoming audio signal is
routed straight to the output jack. This ensures there is no circuity between
the input and output when a buffer is not desired. When the tuner is active,
the incoming signal is muted and the tuner is displayed.
MONITOR MODE: In Monitor Mode, the tuner is always displayed and when not
muted, the audio is flowing through our clean low-noise buffer.
Pressing the Bypass Switch in this mode toggles the mute on and off.
PASS-THRU: When the pedal is bypassed, the incoming audio signal is
routed through our clean low-noise buffer. Pressing the Bypass Switch in this
mode toggles between the tuning screen and the standby screen without muting.
The signal is always going to the output in this mode and can not be muted.
