It spins me out that someone can commercially sell a pedal built so slap dash. Jeez.

So it could be an Electra + a Bazz, or something like that.

I just breadboarded this exact config before reading this thread. (leaving keyboard to start pedal company)

There's a gut shot of the new layout from PGS's demo of this. It looks much nicer inside with board-mounted pots.

or he could actually drill the holes for the mounting tabs that come on pots that for some reason everyone breaks off...

EDIT: didn't see that someone already said that, sorry!

Yes he could do that. He could even do both. But I know why most builders dont use the tabs - small knobs wont cover them and then you have big ugly holes in the face of your pretty pedal. Its no like people are putting serious torque on pedal knobs so the tab isn't all that necessary. If you use big knobs you can make use of them though. IIRC this pedal uses knobs that barely cover the washer and nut.

Small knobs make it hard to put damaging torque on the pot shaft... tab not as necessary. Big knobs make a big lever and you really can put some torque on them... tab much more necessary. A pleasant case where aesthetics and function actually work together.

so we have determined this is a Electra Distortion into a Bazz Fuss.... But what are all the pots actually controling in the circuit?... obviously the Starve is probably just a 5K pot as a variable resistor on V+.....

From the pic it looks like the Bloom pot is just what would be the volume pot of the Electra Distortion... so how are the Gain and Volume set up...Is the Gain just the overal output of the Bazz into another pot for the volume?..

I think the gain pot is really a volume into the Electra and volume is the output of the Bazz.

from the traces I can see in the pic it looks like the Bloom is really the Volume of the Electra...

i'm guessing that Gain is controlling the power resistance on the Collector in the Bazz..... but IDK...

Resurrecting ye oldee thread... Circuit seems simple, but there's some character to it.

Can't make too much of those two images, but here's my guess on the topology (all values, except for non-polar caps are pure guesses). All corrections and speculations are more than welcome. If anyone has access to an original unit, more photos would also be welcome.

I've got one laying around somewhere that I can take apart. IIRC, the trannies are 2N5089s, C3 is a 2.2uF (all the .1's are correct), starve is actually a 100K (weird value for a starve pot), and gain is a 500KB set up as an input level control. I'll grab some pics and resistor values when I get a chance.

Starting to make a bit more sense. Not much, but a bit :)

Well here's a start. I'll need to either desolder the pots for a better shot of the back layer, or trace it out and correct the schematic. More to come later.

Oh, and all the 100K pots are log taper.

Hey all. I've got this on the breadboard and I'm having some trouble with it. It's more of a low-gain fuzz for me, not like what you'd expect at all.

My voltages at the collector seem kind of low too. With 9.45v+ and the Starve pot turned full CW I get 1.315v @ Q1 and .746 at Q2. I assume I've setup something wrong in my VCC section, but I measure both sides of the 47K going to Q1 and I get 9.2v on the Starve side and 1.3 on the Q side. Here's the layout I came up with.

Are you getting 9.45 at both sides of the starve pot?
