I prefer the silver one's, had one for AGES until i bought a 100w Marshall head.
If you've got the cash, sustain punch creamy dreamer.
It has a dial on it that was built by the guitar god himself, turn it fully one way, HEAVY distortion, like monster metal massacre, to the other extreme of ear bleeding clarity fuzzness and anything in between!
That was the only distortion pedal i owned that i really liked.
Not cheap though.
