Newbie Muff Fuzz question need answered

[NH_madman]

Hello all ..Iam a newbie to building pedals and this forum so go easy on me..Iam building a veroboard Muff Fuzz and have a question about the caps used.I noticed on ebay they had 0.1uF radials or disk ..i got the ceramic disk caps will these work with no isses??One more question..i also noticed the cap voltages came in 16v and 50v..now if i remeber right as long as the voltage dont go over the cap ratings the voltage dont matter so i got the 50 for the hell of it..Is that also ok??

thanks

You are correct.  Voltage greater than required and the type of cap doesn't matter at all to my ears.  I'm working on fuzz too- interested to hear how you like this project!

Thanks for the answer man..Iam not new to soldering or building stuff just really rusty(20years rusty lol) Iam gonna do the regular build but add the gain/fuzz  control pot mod

EHX weren't particularly fussy about cap type when they first produced the pedal, and neither should you be.

Note that the classic two-transistor Muff Fuzz is essentially a Fuzz Face, with a fixed gain and a few twists.  It will still distort without the diodes, but distorts more with them.  You can vary the gain of the circuit by running a 5k pot and a 10uf-22uf cap to ground in parallel with the 2k7 resistor to ground shown below.  The smaller the pot resistance is, the higher the gain.  Combinations of diodes/no-diodes and different gain settings will nail you different tones, from warmish grunt to sizzle.

Thanks mark..Iam gonna be using the 2n5088's

Mark for the 5k pot is that a log??I ordered a 2k LOG for the gain and planned to replace R5 with a 680 ohm  resistor and 2k pot..is this ok?

LOL i just realized the notes iam using for a base to do the mods are from you mark..Feb11 2010!!Sorry for barage of questions but would it be wise to replace the fixed 100k resistor with a trimmer for the bias for future transistors i might try?
