Fulltone OCD test 18v vs 9v

Not much difference in it really. 18v Kinda sounds a bit richer in the room I suppose.

18 Volts - Sounds more Open, with better Note Definition, Top-end Clarity and Less Compressed ( based upon this audio sample ). Good Job Man. - Michael Caz - NYC -

Thanks! I always run it at 18v. It just seems to cut through the mix a little better. Amazing pedal. Best rhythm sound i've had in years.
