What do y'all like? The sound clips of GGG's Octavo are killer, IMO & Pedalworx' Octabooty sounds noice as well. The Nick Nitro looks nice (& is low $). Also considering Voodoo Lab's Proctavia. I'll probably goose the octave w/my Hellbilly. Hey, go big or go home, right? I'm not into subtle; I like old school, heavy, 'dirt' rock/stoner rock/metal & am not trying to cop anybody elses tone. I want a 'heavy', fuzzed out octave. Oh, I'd REALLY like to stay in the $150-ish or less range. Thanks.
