Parallel Universe II
Soundclip added. Clean sound running through the parallel Universe (nothing inserted in the send/return).
here is a cool circuit that reminds me of Tim Escobedo's Uglyface. It does heavy fuzz, oscillation and crazy synthy octaveish glitchy sounds.
Note that the send and return needs to be connected if you are not using other pedals through the Parallel Universe's effect loop. The easiest way would be to use a switched jack for the send and connect the switched lug to the input on the return jack. Or simply just omit the send and return and have them connected in the box. But it's when using other pedals through the fx loop you get really crazy sounds... :)

This is the Parallel Universe II. This circuit is very sensitive to input impedance, which can impede the oscillation aspect of the circuit. If you're running a buffer (or several) in front of this circuit, you'll have problems. Even with the gain max'd, a buffer in front will kill the oscillation. To avoid this, I highly recommend adding an AMZ pickup simulator to the front end. This will over come any possible impedance conflicts.

Cool, thanks for the tip! :) I'll update the headline to Parallel Universe II. Cheers / Fredrik

When I have some time, I'll see to updating my vero to reflect this. When I discovered the buffer problem, I had already built it, and was using it at the time. I simply added it into the pedal afterwards. It really should be a permanent part of the build though.

I built this one and finished it today.. woweeee! This thing is so much fun. It's not boxed yet, but I think I'm going to put in expression control for frequency, gain, and tone.. I'll probably put in the little transformer mod Dino mentioned as well. This is a really interesting whirlwind of sonic mayhem, it's not super 'musical' for my playing style, but I was certainly able to dial in very usable tones from the fuzz mode, and then with the oscillate and starve on, it gets super nutty. Thanks for the layout.

Yeah sir! I've been playing with it quite a bit, and I think I've come to the conclusion that it actually is quite musical. So far I've only run a PRS with original dragons and my telecaster with Texas specials through it, and it gets nutty with both guitars, though with the tele I definitely have to tweak the knobs a bit to achieve the same range as on the humbuckers. I'm pretty addicted to these strange circuits that do something typical as the tip of the iceberg, with this vast unseen dimension of audio madness below.. that being said I'm looking at your 'Into the Unknown'. Thanks again for the layouts.

I cant seem to get the starve switch to work it just cuts the audio. Any idea whats going wrong?

I recently corresponded with Colin who created this circuit about it briefly, and he indicated it was very sensitive to type of 386. Sure enough I tried a few in mine and got a world of difference from the oscillation mode. I got the best results and widest range on the oscillation sound from an old radio shack 386 of all things! Thanks again Fredrik

So I made this and tried it in my test box with the send and returned connected directly to each other. All I got was dubstep sounds. I messed with all the knobs and they changed the dubstep frequency. But when I messed with the input wire it didn’t changed the sound at all. My test boxed is set up for the standard 9v,ground, circuit input, circuit output connections. It’s seems like the problems with the input but I checked and it’s dead on with the layout. Should I wire this outside the box instead of using my test box? Like is their a chance it’s because I can’t test this like a normal pcb?
