Guitar Fuzz Effect

Fuzz is one of the classic guitar effects, and this simple circuit generates it quite well. The circuit is so compact that it can be built into guitars or amps that do not have built in fuzz to add that capability to the instrument. The circuit does not use much battery power, so a standard alkaline battery will last many years even with daily use.

Built this fuzz-effect a couple of months ago. It really har a very useable sound ! I would describe the sound as quite wide medium intensity distortion. ( Telecaster.) Thanks Mr C.

for the jack...the lug that is coming down from the lowest point is the gnd (attach it to the gnd) the one that comes down from the top is the +...attach that to the in/out wire if it is the input jack, use a stereo jack and attach the negative lead of the battery to the extra lug. this turns the battery off when the guitar jack isn't in the input.

Just built this circuit on my breadboard using 0.047uF caps and it sounds great! Sounds better than just about any fuzz that I've used. Thicker sounding with good harmonics. I may use it as part of a bigger circuit though... haven't decided yet.
