Voice (Singing Electric) Differential Box (fuzz)

Well-known member
A friend on mine a few towns away recently bought this and had someone clone it. Hardly any information on these other than it's one of the earliest Japanese fuzz boxes. The original has a momentary foot switch. Who knows what the intent was with that. It sounds like your typical 60s fuzz. He only sent two photos. One of the original outside and the guts of the clone. Does anyone have a lead on a schematic? I somewhat sketched something out, but it's a bit odd. Might be a breadboard experiment if I can get some better germaniums. Messenger_creation_13377085-1D8D-406D-A2BF-DAEC80BA7F81.jpeg Messenger_creation_E44AB68D-68FC-4775-9682-B42D0F548D8E.jpeg
 
The clone looks like a variant of the Orpheum fuzz. Here's what I'm seeing:

Pictures that show the values of the remaining film caps and R6 would be helpful if you want to build a clone of the clone. Depth and Volume are probably 250k or 500k.

That looks pretty damn close to what I sketched out. I might ask the guy to get a guy shot of the original. It's more out of curiosity and the lack of info online with this one. Thanks for the info everyone!
