I was out yesterday trying to find a used V3 OCD but the one I saw sold before I could pick it up... I decided to pick up a Zia Drive instead as I am a sucker for Stones tones and all I can say is WOW! I LOVE THIS THING! It actually will probally know my OCD off my main board as I feel like for low to medium gain stuff this beats the OCD but still is in the same ballpark( at least I think so ). It is very Amp like and full of harmonics as well as plenty of beef and sparkle. Its great on a clean amp and a drity one and eventhough it was made to give 6V6 amps a EL84 feel it works wonders on my EL84 amp. It also sounds great with my JR's, SG's and Pauls leaving the tone and character of each intact. This pedal is what the OCD should have been and even though I am a fan of the OCD still, I dont think I will be needing a backup anylonger as it might not ever get stepped on. Great job Alan.
