Captain FX Gear Overdrive / Fuzz ( Skreddy Screw Driver clone) | Reverb

Up for sale a clone of Skreddy Screwdriver overdrive/fuzz. I made it in some older enclosure, but the electronics and everything except the box is new.

No, that's not it....

Back to the drawing board! I'm betting YATS then.

 

[Barry]

I guess he put the wrong back plate on it

 

[BuddytheReow]

This would be a great way to attempt a pedal trace. Can we see underneath the board for all the connections?

 

[Coda]

Too many parts for a classic fuzz, but it could be a modded one…

I just saw this thread and my first reaction was it's a Screwdriver clone! The Screwdriver uses a BS170 (plastic transistor), a BC109C (small metal can silicon) and an AC127 (Ge NPN transistor). It also has five knobs.

Looks like y’all nailed it…. Soon as I get another chance to dig inside I’ll post my findings and see what’s going on with it…. Down the rabbit hole I go

 

[swelchy]

Confirmed from the builder it’s a screwdriver clone..

 

[iamjackslackof]

Lucky you then! Screwdriver is my favorite fuzz ever.

Alright, a Screwdriver clone, that's great, but the real question is: did you listen to Cows?

Because that back plate is right, you should.
