Harmonic Percolator & Systech Overdrive 2in1 Pedal
Posted: Thu Jun 19, 2014 5:42 pm
The idea was to build a Harmonic Percolator 2in1 pedal with separate in/outputs so it can be routed in multiple places on a pedalboard.
So the Systech OD half… I hate perfboard, stripboard… all of them… Since I couldn't find a PCB I decided to just make it. It's more time for me but it'll give a much better looking build. Here's the schematic drawn in Eagle:
I worked out a PCB layout. I have to boards left too if you don't want to make them yourself. They're designed to fit in a 1590A
Printed at OSH Park:
Filed the edges nice and smooth:
Partially populated:
I don't have many pics of the HP part but here it is with all it's mojo. It just needs a few more parts.
And the enclosure it will go in:
Drilling template attached
Drilled
Mockups double checking for clearance. Nothing is perfectly straight since I didn't tighten the parts down.
Nearly there, just needs the germanium soldered in for the percolator.
Finally done!
I was sent a knob less than I should have so it's got my tele knob on there until it arrives.
The Systech Overdrive sounds fantastic! I'm building it off schematics I've found online so I'm going to compare it to some online demos and see if it needs any tweaks. But hey, I think I'm gonna build myself one exactly like this. I'll probably add an expression input for the EQ since it's very wan-like. If you want a cocked wah fuzz, this is it!
