i have several DOD pedals, and in general i like them.
201 Phasor - nice 2-stage phaser, almost chorus-like
490 Phasor - 4-stage chewy phaser
FX10 Pre-Amp - transparent and the best boost i have tried so far
Buzz Box - nice octave fuzz, gets close to Neil Young's tone
Punkifier - nice toy, hard to control but has a unique fuzz sound to it
