the Dano coolcat drive and the Fulltone OCD are rumored to be similar, so I picked up a Dano to demo against the Version 1.4 OCD. I used a 59 Historic Les Paul and my Dr Z maz 18 2x10 combo for the shootout. The pedals were very close in tone...I still favor the OCD, but that may be from my own self-admitted tone-snob view of these potential clones of other pedals. I tried to remain neutral...tried!
