I've been reading up on pedals I could get to give a big sub bass sound for a short passage of one song my band plays. I was hoping the OC-2 I have would manage it, but so far I haven't had any luck (not enough volume or bass, too synth-y). Best option seems to be the DOD Meatbox (although price is ridiculous these days) or the Mantic Hulk. The videos I've heard of them sounds exactly what I'm looking for. Aguilar Octamizer sounds like it could also be an option. I'm not looking for a synth-y octave tone though. A few questions for those that have experience with big sub-bass sounds: Has anyone had any success using the Meatbox or Hulk through an amp, rather than direct to PA? I'd really rather not have to go direct to PA to keep life simple. Obviously this would mean not going too heavy with what the pedal is outputting. Does it still have the deep sub-bass effect if you're pulling back on settings enough not to blue speakers? Has anyone had any success using the OC-2 for sub bass, non-synth-y tones? Would an EQ pedal with extra gain on tap help? How does the Aguilar Octamizer do for sub bass? Should I suck it up and buy a Hulk and a DI and go direct in to the PA if I really want to make people vibrate? Thanks!
