Per request. A slightly modernized take on a Moog designed Fuzz/compressor hailing back from the 70s. The signal path remains true to the original but the rotary switch has been removed in favour for a variable fuzz control. And the two compressor settings is now fed through a toggle switch. The CD4007AE IC might be hard to source but it is avaiable at Ebay.
Schematic is avaiable HERE.
is the CD4007AT necessary (very hard to find) or will a UBE and others work as well?
ReplyDeletePer the folks at Electronic Audio Experiments that posted the schematic Anders drew this from, the 4007AE is crucial and a more common UBE won't do it. I ordered some from a couple different sellers on Ebay - one in the UK and one in Greece. Because, as EAE also stated, the circuit is "finicky" even with the proper chip and it is best to try a few different ones.
DeleteMinor edit, Anders - it's 28x29 on the board size - hopefully my only one! fingers X'd
ReplyDeleteHas anyone actually built this and can confirm it works. I built it and went through it with a fine-tooth comb and cannot get it to work at all.
ReplyDeleteHey James - I tried multiple times to get this one to fire up and could not. Whether it is an error in the schematic or my CD4007AE, I was unable to get this one to work and abandoned it.
DeleteHey everyone - Electronic Audio Experiments just a couple of weeks ago released a DIY PCB of a modified Maestro Fuzztain circuit that will work with a standard CD4007UBE - just got one, gonna build it, then try to work up a strip drawing for the schematic, unless of course, Anders beats me to it!
