Help cloning this fuzz pedal Please

Okay, that makes sense. I've considered doing that too, but lately I've just been running everything on batteries.
I suppose you could flip everything upside-down and be able to use it as a negative ground - there's nothing wrong with doing that.

Which will work just fine about 30% of the time in my experience. Its VERY common to get motorboating and oscillation issues when trying to run PNP germs as negative ground. Ask RG.

woahh! all that you guys have done is amazing, ive been away all weekend so havent had chance to check back on replies, il get the values up later.

thanks a million for all this

ok using this as reference:



i got this:

R1 =  91k jd
R2 = 30k5
R3 =  red brown brown black red grey
R4 =  68 drod
R5 =silver red brown
R6 = 6.2k5
R7 = 30k6x
R8 = j63
R9 =  51kjz
R10 = 6.2k5
R11 = brown red silver

C1 = 332
C2 = 50v 22uf
C3 = orange
C4 = orange
C5 =

ok i dont know if that last post was jibberish. Il have some spare time over the next week or so, so il try get this down. The wiring should be no problem its pretty simple using the pedal i have as reference. I just need to source all the parts.

BUMP

plus i got an e-mail back from the pedal maker and i dont think he speaks englisg so no help there, my italian aint too good

hmmm...

Ha! Thought I`d seen the name T-Fuzz somewhere before. Must have been while scanning analogguru`s site.

I`m thinking, what with the values you`ve contributed and those on Herr Divos`s schematic we should be able to cobble together a working version. Unfortunately, I`m finding the software slightly inadequate to the task of replicating the tight layout of the original.

For the sake of clarity I might need to re-jig it. This would necessitate making the board slightly larger which would be a shame as the original is a model of economy.

[limlam]

what software do you use for making a layout?

If you want to run it negative ground the easiest thing to do is use NPN trannies and flip the power and any polarised caps. That way you've got no worries about motorboating or other nasties.
