Never bother to have an octave pedal until last year. I'm starting with Mooer Tender Octaver but it only last few weeks (sold it for more than I pay). After that, I'm not convinced to bought another octave pedal. Finally, few months ago, I give a shoot for TC Electronics Sub n' Up. After few months, it can't give me the sound I'm picturing in my head, so sold it. Two days ago I've got a chance to buy Boss OC-2 (MIJ and MIT), finally yesterday I pull the trigger on MIT one because it's $20 cheaper. It arrived today, and after work, I play it for an hour. The sound was good, even the oct 2 that people don't use much. The only thing I want to ask is, I run the OC-2 with Hyper Luminal before it. Why it's distorted my signal? Overall, it might be a keeper and my journey to find octave pedal is done.
