Menatone Carcrash clone?

[small fish]

Hi everybody,
although I´ve searched a lot of DIY communities, I never found a clue on re-build Menatone pedals (well, actually a lot of clues, but no working project....just a perfboard of the Red Snapper).

Anyone got a Menatone Carcrash built? or built one?

I´ve listened to some you tube clips and I think, it´ll be a great pedal to built.
Any hint will be highly appreciated!!!
