Thanks a lot. This was a very curious device. From under the hood it looks very random.

The Adjust control circuit is a positive feedback loop. This is what creates the oscillation. The switches do things to change the timbre and frequency of the oscillation. That's really all there is to it. The extra element you don't see in the schematic is the guitar's pickups and controls, which can have a very pronounced effect on how the circuit behaves. This is good because you can easily change sounds by making adjustments on the guitar without needing to bend over and mess with the pedal. You can leave it on one setting and get many variations from it with just the guitar's volume knob and pickup switch.
My favorite sounds are when you get it to produce a deep synth tone that is controllable by the notes you play on the guitar - though what comes out is not necessarily the note you played! As chaotic as it is, I am finding it to be very useful and playable. I would say it's more than just a noisemaker; with careful adjustment, you can use it as a mutant guitar synth.

Thanks for doing this one Martin!
I so dislike the modern digital world that I need to use semi-digital effects to emulate the analog world of cassette, VHS, and vinyl.

That's a sweet PCB. The board mounted switches save a nightmare of wiring.
Thanks for the schematic, soulsonic! Good eye catching that resistor.

Did you guys know that this "Japanese'" company actually builds its pedals in Sydney Australia? Yep, they guys Japanese but he lives in Sydney. I saw it on their website last year or the year before but up till then I thought they were made in japan.
Or something like that anyways.

Oh, I see. That answers the question I had about it. I saw the "Made in Australia" sticker on the back, and it really confused me because everything about the website suggests that it's a Japanese thing.bumblebee wrote:Did you guys know that this "Japanese'" company actually builds its pedals in Sydney Australia?

It also had a warning that it was built "using special tools" and said that this might render it impossible to re-assemble if taken apart. I didn't have any trouble putting it back together and the most specialized tool I used was a nutdriver.

Perhaps it's in reference to the 4PDT. Arent those still pretty unreliable? If you mounted it back in the case and set it up too high, it would probably be very easy to break.oldgravity wrote:I think that's just "psychological goop".soulsonic wrote:Oh, I see.

This is a guess, but judging by the giant washer used on the switch (inside) from the gut shot...

I love the look of the stomps they use though. And its good to see a decent company come from Australia."A MOJO RISING"

Hi there,
is there already a pcb/vero layout out there anywhere?
I'm already working on one... still busy getting the layout right...
Has anyone already built this?

*bump*... Some treat for you...
Also... here's the already verified layout. Only one little flaw: I don't know if the switches are reversed... but it works fine for me though.
Have fun

Last one is imho the best sample. At least it encouraged me to build this effect.
Well, sorry no samples of mine... i'm not the guy who likes to record stuff to put it on the net
Also I don't play guitar... btw, it works really fine with bass, too
Edit: sorry, i was too slow
