Let's hear what you say! There are many options of course....
I'll start by saying Maxon Sonic Distortion SD-9. A very smooth and fat sounding distortion pedal.
For a super cheap, good sounding pedal, I say Danelectro FAB Distortion.
The Proco Rat is also great, but I'm not quite sure which model is which anymore - Turbo Rat, Rat 2, Rat this, Rat that. Maybe someone can clarify this.
For overdrive - the already legendary Zonkin' Yellow Screamer, by our very own DuhVoodooMan himself! (Ask him nicely and send him lots of gifts if you expect him to make you one...)
What rocks your world in the distortion pedal department?
