loks a bit like a tweaked big muff (swollen pickle ,perhaps??)
bet it goes for some serious bling too....
just seen the one knob fuzz at www.macaris.co.uk
£109....whoo, or about £5 using dragonfly's layout...
I'd be quite suprised if that really does go for top dollar 'cause the Colorsound collectors really are into the vintage gear and I'm not sure if that one will get the interest for big money. I've got a cupboard full of 'vintage' Coloursound gear and I honestly swear that the 'clones' I've built sound better (with the exception of the Octivider maybe.)
Cheers,
Nick,
