Marshall JMP-1. Mine has Mesa tubes in it, and it sounds great. I can get all kinds of great tones-not just distortion, and being able to switch between the direct outs and the speaker emulation is great. It also has an effects loop that usually put the Moog low pass and ring mod on for tweaking.
Cinch Labs Oscillator Fuzz. I picked this up from a guy who makes them on ebay. It's a copy of the Death By Audio version, but it only cost me 90.00 instead of 300.00. Built like a tank with arbiter fuzz, oscillator, and a boost knob. The osc can be turned off, and the fuzz and boost sections both have bypass buttons. Nasty, nasty.
