Thats one Ive never seen either. It makes me wish I had a bunch of "expendable" money. It sounds cool from the description.

Looks like a Mk1 Tonebender box, and the insides look pure Colorsound.

Sorry to raise such an old thread but I have just picked up one of these Park Auto-Wah pedals, it's in need of some TLC. I wondered if anyone had ever drawn out the schematic for this at all. There are not many components inside and it shouldn't take long to trace but if it has already been done it could save me 20 minutes drawing it out. :wink:
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !

No silicon heaven ? preposterous ! Where would all the calculators go ?

I had assumed it was going to be an envelope filter type "autowah"...

Is that four transistors? Perhaps a phase shift oscillator like schaller trem LFO coupled with a twin-t wah like the colorsound?

There are 5 transistors which are 2n3702 . I did make some pictures of both sides of the pcb , I will post them as soon as I get a chance.

Sorry for the oversize pics, I have no idea why that happened ? right click and save for full picture.
