I've got some gutshots if this one. Anybody interested in tracing and cloning this one?

There's a lot going on in here. I've got more shots coming, including pot values and the other side of the board.

I also see an Atmel. So a piece of software will also have to be written if this pedal will be cloned.

I'd be willing to bet that the Atmel device is simply controlling the relays on the board. If so, cloning this beast shouldn't be horrifically difficult.

There are 5 relays which match up to the various things that are switched in and out. Should be straight forward but need more res in the photos!

No problem. Gimme a few days and I'll get some more up.

Here's the large ic and the pot values and traces from the toilet side of the PCB. I'll get a list of the other ICs and SMD components up asap. I've got a video of the board too if that helps.

Do you have any more photos?
The circuit looks to be substantially the same as the VH4 pedal. Values of the components R1-R20 and C1-10 would probably be the main differences
