Not a finished pedal - hope that's OK.

My prototype board inspired by the Beavis Board. The pcb is an tl072 buffer into a 4053 for switching. The other half of the tl072 is a low impedance 1/2 V+ buffer for biasing.  I figured out a cool way to mount the posts using two 3 way binding posts back to back. The pots screw into place and I can swap them out in a matter of seconds - there is room for five 16mm pots there.

The yellow box to the left is a lm386 amp with a 3 inch speaker, unfortunately I have to take the board to the practise space to try things out at a decent volume.

The board has a Rat breadboarded on it - I spent 45 minutes trying to figure out why all the schematics on the web have the tone control wired backwards. I finally read that the Rat "Filter" is supposed to work the opposite way from a regular tone control.

The binding posts for pots are great idea!

The alpha pots with the straight pins have 0.2" spacing and are a perfect fit.

JaM drive - based on BSIAB, heavil modified; from crunch to wild british tone. With mosfet boost for solos or as standalone boost.


Notice those nice white washers? They look cool :icon_twisted:

JaM FX is our name... not the same, by sound an design. They are from Greece, and we from Slovenia. Sorry, we didn't know they existed, when we started making pedals.

And a gut shot:

Nice!So tidy...

I saw you got some jacks from tayda....
I was wondering if these are worth their price.


I have bought some of the plastic ones(insulated) and hell yeah they are!

Uf, this mess isn't tidy at all ;D You should see what is hiding beneath the pcb-s :icon_smile: And there is an error on the PCB, so i had to use green wire to corect it ;D

I love everything from tayda! Those jacks are great! Great quality and sturdy!
