Hello all,

I am trying to build the muff fuzz on veroboard using this layout:

Wired it up and nothing at all. I didn't have any 680k so I used to 470k instead....dont think this would cause no sound at all. Does anybody know how I would go about testing a 4558? I only have this one and I am thinking it might be the problem but I am not sure how to test it.


Thanks!

Only way I can think of testing an Op-Amp far from socketing another circuit and trying it in that is something like this http://tangentsoft.net/elec/opamp-tester.html if you have another dual Op-Amp spare that isn't a 4558 you could try it aswell (assuming you socketed it which I hope you did)

Also I can't remember the schematic and I only just woke up but I think the 680k might be an fairly important part... although it not working cause of it sounds unlikely but if you have an 210k (or close) resistor you could run it in series or if you had 2 larger values you could run them in parallel.
