My Fulltone '69 Pedal cuts fine. It actually cuts more when I use the neck pickup and turn the tone down all the way! There's a point between 1 and 2 on the knob where it gets nastier as I lower it! It goes "Ooh-Wah" as the tone knob is lowered. Even the drummer can hear it.
I swear that this works better on the guitars that I have PIO caps in!
That's the voodoo that I believe in anyway!
