Natural Overdrive looks like a 18V Electra variation.

Dual Fet looks like an 18V Fat Boost variation.

Nice looking pedals.

Hmmm, the Quatro Overdrive has the 14 pin 3403 in it. I wonder if the circuit is any relation to the OD-1....

Thanks for the link!

Yeah, they look like Dale RN55.
I used some RN55 and RN60 in a booster recently with nice results.
They are a good choice any time lowest noise is desired.

I'm looking at the gutshot for the Fulltone '70; I'm not seeing any diodes anywhere either on or off the board. You know, those diodes that are in every version of the schematic I've seen... :roll: The board looks exactly the same as the '69 except for some component swaps.

Either the existing schems are wrong or there are 2 versions. The pedal posted there is exactly the same as the one from the 70 thread.

None of the schems show the 18K resistor that is clearly on both gut shots. Also missing from both boards is the other 10pF shown on the schems.

I'll post the link of the 2nd. gut shot in the old thread :wink:

Just bought it. Will test it against my modded RAT to Landy Specs and BJF Dyna Red.

A very wise decision... you will get rid of a piece of shit (ty goop).

Looks like the BamBasic Dual FET Booster uses a voltage doubler.

The craftsmanship is very nice. The guy has some attention to detail. Looks like he uses a mix of high quality caps with carbon resistors.

The Quantum Lead Fuzz looks like it could be a BMP variation. I see four transistor and what look like two sets of Si diodes behind the center two transistors.

What's this thing plugged into the input? Is it some sort of wireless system?

For some reason I had a dream about this, and in my dream I thought It was a radio receiver for a wireless transmitter.

I'm convinced the box is a Big Muff.
