marrk	Re: EH Small Stone & CS Tonebender problems Regarding the Tonebender, double check the polarity of your diode placement, and make sure your Fuzz pot is 250K, not 2M as indicated on the schematic. The resistor on Q2 emitter is 3.3k, it looks like 33k, but it isn't. Also, try a different transistor, AC128 are notoriously variable in quality. From what R.G. has said, all the fuzz happens with the diode and Q3. Try swapping that one first. The way Q1 and Q2 are arranged, you might even try silicon (heresy!) devices. While we are discussing the Tonebender, I've been trying to find a way to make the circuit more responsive to the guitar's volume knob. It seems whenever volume is set below 7 on the guitar, the sound gets stuffy and doesn't clean up too well. Can anything be done, or should I just keep using my fuzz face
