Muff Fuzz drive!

[tiges_ tendres]

So I think I'm becoming a tweaker!!

I perfed this up from the schematic that's floating around.  I socketed the input, output caps and the diodes.  The other major change was that I made my own layout to accomodated an SIP-8 4558 chip that I got in my removed parts selection from analog man mike (thank you!)

I put two 1n34a diodes in, and all the fuzz was gone!  I was left with an awesome over drive sound! 

I didnt really like the stock sound of this one, a bit too bassy, the fuzz wasn't really doing it for me.  I tried LEDS, all kinds of diodes, but the combination of the 2 germaniums blew me away.

I cant decide on what caps to put in the circuit, I think I'm going to put two rotary switches in, hopefully, with 7 caps on input and 7 caps on output.  When you pull one of the diodes, the fuzz comes back, so I think I will add a 'lift' switch also to lift the one diode out of the circuit.

If my math is correct, that will give me 98 different combinations!  more than any man needs.

*edit*  I should point out this is the opamp version, not the transistor version.

Any chance you can make some sound clips?  I was just looking at the opamp muff today.  I'm very interested.

I'll see if I can have a crack at it.  Ive got an opamp muff fuzz and and an opamp big muff, I'll see what I can do.

I really like the idea of rotary switches... where do you get some of those, or do you have to make them?

most places have rotary switches of some kind or another.

thanks!!! I needed to know this!

I got side tracked and built one of these last night... unfortunately it does not work.  Only lots of loud hum...  I was too tired to really get into it late last night but I did take a quick look at it this morning.  It seemed that the circuit was correct and I think it's wired right.  I'll have to take a look later tonight. 

Any ideas?

The Mockman is a similar circuit.  See this current post.

sorry, I cant figure out my sound card, so no sound samples.  I could maybe put it on cassette at a push!:)

and thankyou wgtp for those links!

[bass_econo]

Oh well, thanks for trying.  I built it last night but it has some problems.  I'm going to look at it again when I get home.  I hope I can get it going.  I'm going to build the Mockman too.  I love all of these opamp distortions.

If I get mine running tonight I will make some soundclips.
