I could probably get close with an OC-2 doing octave down and a fuzz pedal.
What fuzz? I run my OC2 into a Blower Box and a Fuzzolo before, but I'm not digging those for a synthy tone like in the OP. I'd love to have a fuzz that gets synthy and yet is not so over the top that I get huge volume differential every time I turn it on. Basically something that I can slide in while playing some Jazz/Funk and still have it make sense.
