Hey, all. My wife made me an offer last night (not THAT kind...

) - quit smoking, and she'll buy me a pedal.
Difficulty: Under $200.
Here's what I have currently:
Crybaby Bass Wah
Pork Loin
Sansamp Para Driver
Joyo Voodoo Octave
Boss Bass Chorus
Boss DD3
Boss PH3
Boss BF2
Danelectro Cool Cat Tremolo
Digitech Whammy 4
Guyatone BR2 (going up for sale this weekend)
Boss RC3
Music I play: Post-rock (think Tool + Rush + some Foo Fighters with a sprinkling of QOTSA). I also noodle on my own - ambient noisey stuff.
I've tested out other dirt pedals (El Oso, Tubescreamers,Big Muff, etc.) and I think I'm set there. I've also tried some bit crusher type pedals, and they're not my thing.
I've been talking about getting an Iron Ether Xerograph Deluxe, but I'm not sure if it would be useful (or fit with what I do). Since I can't test one out locally, it's tough to say.
I guess I'm looking for synth-ey, unusual pedals that could work with what I already have, or bring something new.
Thanks in advance!
