WALRUS AUDIO Canvas Digital Tuner
Thank you
Thank you for trusting your instrument’s tuning to the Canvas Tuner!
Out of the box, you’ll find the tuner ready to use in vertical needle mode.
Simply connect to a power source* and your instrument’s cable to the input
jack and you’re ready to tune up. Canvas Tuner has a lot of options to explore
including screen orientations, needle or strobe mode, tuning presets, screen
savers and more, so read on to get the most out of your new tuner!
*Only use a 9 volt DC, Center Negative, 300mA to power the pedal. The use of an isolated power supply is recommended for powering all Walrus Audio Pedals. Daisy chain power supplies are not recommended.

TIMER
TIMER STANDBY SCREEN
To use the timer as your standby screen, simply navigate to the Standby Screen
menu option then select Timer Mode. Now when you bypass your tuner, the timer
will be shown in a large font on the standby screen. From the standby screen,
press Up to reset the timer and set a new time or Down to pause the timer.
Note – After the timer runs out, it will turn red (the same color the
venue owner’s face is turning) and begin to count up. Follow the steps above
to reset or pause the timer.
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.
TUNING PRESET: Select pitch ranges that the tuner will display and
detect.
NOTE: When using any tuning preset other than Chromatic – When an
incoming note is outside of the tuning preset range, the tuning needle will
show as a muted red color and remain off to the side and brighten as you get
closer to your target note. Left for flat, right for sharp.
CHROMATIC: Tracks the full frequency range of the guitar signal.
GUITAR STD: Tracks the frequencies only in the standard EADGBE guitar tuning range.
DROP D: Tracks the frequencies only in the standard DADGBE guitar tuning range.
BASS STD: Tracks the 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.
DADGAD: Tracks the frequencies only in the DADGAD guitar tuning range.
FACGCE: Tracks the frequencies only in the FACGCE guitar tuning range.
OPEN A: Tracks the frequencies only in the EAEAC#E tuning range.
OPEN D: Tracks the frequencies only in the DADF#AD tuning range.
OPEN G: Tracks the frequencies only in the DGDGBD tuning range.
SWEETENED “BUZZ FEITEN”: Tracks frequencies based on the pitch offsets
defined by the Buzz Feiten tuning method. Note: This preset should be used
with guitars setup with the Buzz Feiten tuning system.
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.
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.
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.
