I built a Muff Fuzz based on Gus' mods and it has a really nice smooth distotion, but is noisey as a hurrican. Is this typical for a dual op amp device?
Hi there,
I built one using a 1458 and I have an original that's part of an old (and friggin' huge), EH "Crying Tone Pedal" - and they're both noisier than hell. :) They do sound cool though...

What mods did you use? The ones I built were not to noisy. What IC did you use? The circuit has alot of gain.
I have a updated schematic. Moose built one for bass. Its a ultra fuzz at 9V meets a muff fuzz with values picked for different usage guitar bass etc. Aron you can post it if you want Sick bass fuzz.

I put a 1 meg resistor in each loop 1 SI diode in the first stage (like the Mosferatu) and 2 in the second. If I put a 220pf cap in each loop that helps a lot, but cuts too much treble.
I'm wondering if the input cap might be noisey. It measured 160K but showed something else the outside. Maybe bad.
I have tried 6 different opamps. 412, 353, 052, 072, 4558, 4559.
