TS PG-3 Overdrive Pedal
« on: June 18, 2020, 06:21:17 AM »
Recently I found a bunch of guitar related things on the curb during my town's yearly junk day. There was a couple of small practice amps, Fender tuner, Realistic amplifier, cables, ect. Unfortunately, it was all in a five gallon bucket full of stank swamp water. Yeah, that was frustrating.
Anyways, I took the lot home, disassembled it all, and gave it a scrubbadub with a hose and a bristle brush out on the sidewalk. Amazingly, I got it all working.
One of the practice amps I found was a TS PG-3 Overdrive. It's one of the generic 3w amps you see with names like First Act, Ammoon, Aroma... The speaker was ruined and I wanted the 386 power amp for another project, so I dissected the overdrive circuit and built a pedal out of it. I added a switchable voltage doubler for fun and it worked pretty well.
Below is the schematic I drew up from the OD and the box I put it all into. The box is wood, originally a 80's Polo gift box with a slide-out lid. I covered it all in black patent leather and used the corners and rails from a busted storage box to dress it up a bit.

Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

I'm glad ya'll liked it. I gave the pedal away but it was fun to mess around with while I had it.

If anyone has one of these PG-3 amps, please take a moment and see if yours has the value of the unknown capacitor listed on my schematic. All mine had was the polarity marked.

Also, does anyone know a source for the L channel rails I used on the box? I found the manufacture online but they only sell it by the ton ($2,100-$2,500). I don't quite need that much...

You are a better DIY man than me.   I would have looked at the stank swamp water and kept on walking.   ;D
This is really impressive.  I admire your ability to see beyond the 'junk' and create something fantastic.  Kudos.
