OUTPUT JACK (#16)

: Connect a MONO 1/4” shielded guitar cable going to other effects and/or your amplifier.

The 

TREADLE ADJUSTMENT

 

NUT

 

(#17 above, and #7 on Previous Page) 

determines how much pressure it takes to rock the Treadle backward and forward. If 

you find that the treadle feels loose and doesn’t stay in a fixed position, use a pair of 11mm open-end wrenches to tighten the nut by holding one of the wrenches 

stationary and turning the other wrench CW no more than a 1/4 turn. Check the treadle action, if more is needed continue tightening 1/8 turn turn at a time until 

you reach desired feel. Do not overtighten, as this will give the treadle too much resistance and make rocking it back and forth too difficult.

The

 FWP-2 200k Potentiometer Gear (#18) and Rack (#19) 

are essential for creating the “wah” range of sound and are adjusted to perfection before the pedal  

leaves the shop. Do not adjust this unless you are experienced or damage will occur and your warranty may be voided. This pot has a limited rotation and takes 

skill to adjust correctly. Visit youtube.com/fulltoneeffects for an instructional video regarding adjusting and maintaining your wah pot correctly.

CLEANING THE POT 

is occasionally necessary every 6 months or so or when you hear a scratchy sound as you rock the treadle back and forth. Open the pedal, 

pull back the vinyl dust cover 

(#20)

 and spray only a half seconds worth of Caig DeOxit D5 Tuner Cleaner/Lubricant directly into the opening of the pot. Then rock 

the treadle back and forth 10 times or so, push the vinyl dust cap back over the opening, and you should now have a quiet wah pot.

BUFFER/BOOSTER (LEVEL #13, SWITCH #14): 

The JFET buffer/booster is only active when it is switched ON and when the pedal is turned ON. It allows the 

wah to work better with certain pedals and hi-gain amps. You can also use it as a volume booster so your Wah will cut through the mix when it’s turned on. Too 

much boost will overload your amp, which may or may not be desirable.

DC POWER PORT: (#15) 

You may run this device on a 9 volt battery, a high-quality, regulated 9 volt DC wallwart (not included), or high-quality 9VDC to 18VDC

WARNING! 

Avoid unregulated power supplies because they induce hum and other noises. Avoid switching-type power supplies (except for our IPS-9) as they can 

inject noise that will be heard through the amp.
