Connecting
Input jacks - Use MONO for mono input and both MONO
andSTEREOifconnectingastereosource.
If you run the pedal on battery, we recommend removing
the mono input jack to preserve battery power when you
don’t play.
Output jacks – Connect to another pedal or directly into
an amp or mixer. Use MONO for mono setups and both
MONOandSTEREOforstereosetups.
Notice that it is possible to select between true bypass and
buffered bypass mode via a dip switch located under the
battery cover.
Power in–Usea9VDCpowersupplywiththefollowing
symbol:
USB
Connect to a computer using the supplied USB cable for
uploadofTonePrintpatches.
Theconnector-typeisMini-B.

The Controls
FX LEVEL
Controlstheintensityofthechorus.Thechorusingeffectoccurswhenapitchmodulatedsignal–think
vibrato–isplayedadjacenttoacleansignal.Thereforethemaxchorusintensityisachievedata50%
wet/dry mix. With Gravy, this is achieved by setting the FX level fully clock-wise.
SPEED
TheSPEEDknobsetsthechorusspeed–fromslowsmooth“Hi-Fi”tomuchmoresignificant“Leslie”
types at high speed.
DEPTH
DEPTHsetstherangeofthemodulation.ExperimentwithboththeSPEEDandDEPTHcontrolstoget
the effect you are looking for.
TONE
By adjusting the tone you can set how warm you chorus should sound. When using high settings on
bothspeedanddepthforthat“leslie-type”soundyoumightwanttoemphasizethelowerfrequencies
overthehigherones.TryturningTONEcounterclockwise.
CHORUS/TONEPRINT/VIBRATO SELECTOR
Theselectorswitchallowsyoutoselectbetweenthe3differenttypesofFX.

8
TRI CHO (Tri-Chorus)
TheTri-ChorusisavariationoftheregularChorusthatusesthreestereoChoruseswithvariousoffsets
for both depth, speed, phase, and chorus delay time to produce a unique, very broad and lush Chorus
sound.TheGravyhasbeenvoicedespeciallytonailthatold-schoolfatchorussound.
TonePrint
Consider the knobs and switches on your pedal as a few handles that actually control a large number
of parameters. Dedicated staff has defined the controls, - but wouldn’t it just be cool to let the world’s
leading guitar players contribute with their own definition of how the controls should work?
YES-thisisTonePrint.
OnceyouhaveselectedTonePrint,allcontrolsreactexactlyasdefinedbytheartistthathasprovided
theTonePrintandchangingtheTonePrintinyourpedaliseasy:
• ConnectthepedaltoyourMacorPCcomputerusingthesuppliedUSBcableandnavigateallthe
availableTonePrintsatwww.tcelectronic.com/TonePrint
or
• DownloadtheTonePrintAppfromGooglePlay or theAppStore and follow the on-screen
instructions.
VIBRATO
InthispositiontheGravypedalactsasaVibrato.Thesignalispitchmodulatedbutunlikeinachorus
theoriginalsignalisnotplayedadjacently.Takeyoursoundfromsubtlepitchmodulationtoanall-out
Leslie-typefeelbyvaryingtheSPEEDknob.

Bypass modes and Kill Dry on/off
Unscrew the back-plate and look for the two small dip-switches in the upper left corner.
Theupperdip-switch(closesttotheDC9Vinconnection),switchesbetweenTrueBypassmode
(default) and Buffered Bypass mode.
True Bypass – is a hardwire bypass that gives absolutely no coloration of tone when the pedal
isbypassed.UsingTrueBypassonallpedalsisaperfectchoiceinsetupswithafewpedalsand
relatively short cables before and after the pedals.
Buffered Bypass –If you use a long cable between your guitar and the first pedal, if you use many
pedals on your board and if you use a long cable from your board to the amp, then the best solution
True Bypass Buffered Bypass Kill-Dry - off Kill-Dry - on

10
Changing battery – Unscrew the thumb-screw on the back of the pedal and detach the back-plate.
Unmount the old battery and attach the new battery to the battery clip making sure the polarity is
correct.Thenremounttheback-plate.Tosavebatterylife,removetheinputjackwhenyoudon’tplay.
Batteries must never be heated, taken apart or thrown into fire or water. Only rechargeable
batteries can be recharged. Remove the battery when the pedal is not being used for a longer
period of time. Dispose batteries according to local laws and regulations.
will most likely be to activate the buffer in the first and last pedal in the signal chain. Can you hear the
differencebetweenapedalinTrueBypassorBufferedBypass?Maybe,maybenot,–manyfactors
apply; active/passive pick-ups, single coil/humbucker, cable quality, amp impedance and more. We
cannotgiveasingleultimateanswer.Useyourearsandfindthebestsolutionforyoursetup!
Kill-Dry on/off – With Buffered Bypass activated (upper switch to the right), the lower dip-switch sets
Kill-Dry on/off. Kill-Dry removes all direct signal from the pedals output and is the mode to use when
the pedal is placed in a parallel effects loop.
Kill-DryisNOTanoptioninTrueBypassmode.
