Here are the pics I got. I don't have it anymore, but I got most of the IC's and all of the pots (if those are needed outside of the pics).

Thanks for the pictures!
It would be awesome if some guys here would hack that great pedal, but it seems to be quite tricky...

Good luck :horsey:

That's awesome, the LFO is being generated by the pic, hence the multiple waveshapes.
Anybody else taking bets on there being a version in the works with MIDI sync?

EDIT: Either way, it's a Boss VB-2 in fancy clothes.

I see the two LMC6464s there. Had to look that up: "Quad Micropower, Rail-to-Rail Input and Output CMOS Operational Amplifier"

Can anybody see the THAT chip that's supposedly responsible for the compression?
It's not a circuit i'm that interested in cloning, given that my Marshall Supervibe sounds exactly the same, but i'm still curious.

It's the SMD IC next to the BL3207, T(HAT)4513.

Has anyone also spotted the pic controller chip that probably needs to be programmed unless it can have the data ripped no go as far as i can see.

If you do a search, there's a website with code for a PIC LFO somewhere, my guess is it's not too difficult to do.
PIC's can often be blown with a non-read function, so it's likely that the code can't be ripped. However, you could easily knock up a relaxation oscillator to do the same thing in an analogue fashion.

Actually it's a THAT 4315, no biggie :slap:
