I play "bake-rock".
I wouldn't say any one pedal is do-or-die. They're just fun and cool.

I use either a Rivera Quiana 2-12 55w or a modded Leslie I just picked up. Or sometimes a VC6Q through the monitors with digital outboard FX.
Here's what currently on the floor and in the rack:
Vintage Mutron Octive Divider
Vintage Mutron III
MoogerFooger 102 Ring Modulator
MoogerFooger 104 SD Analog Delay
Moog CP-251 control voltage processor/mixer
4- Moog expression pedals for use with the MoogerFoogers
KLON Centaur Overdrive This really is a great piece. It's the one thing I find myself using all the time. I've run Moog Voyager, Roland JV1010, run it into the Leslie, put a P-Bass through it. Everything sounds bigger and badder with it.
So I guess there is ONE pedal......
Roger Mayer Voodoo Vibe
Geoffrey Tease
RMC3 wah. Very cool too. Lot's of quack!
Ernie Ball VP Jr. volume pedal.
Vintage MXR 10-band EQ
Leslie control pedal. That's a must-have item there!!!
Rivera FS-7
Roland SDE 1000
Lexicon MPX1
Also rans.......
80's Morley Pro Flanger and Rotating Wah. The rotating sound on that one is pretty bad, but the wah is very cool. I restored it. Got that one off Ebay was DOA.
Check out the MoogerFoogers if you want something different. Control voltages are fun and you can change all the main parameters of any of their pedals on the fly. Increasing/decreasing the delay time on the 104 does pitch bending. You can also adjust the Mix and Feedback. The Ring Modulator sounds good on electric keyboard samples and can do some very weird stuff with guitar. Not all of it very musical.
What I really want is a pitch > trigger/gate/control voltage pedal from Moog so I can plug my guitar into my Voyager and play true analog synth with a guitar. THAT would be my ultimate rig.
