I agree with Sunvalleylaw. I've played a few overdrive pedals including the Boss Bluesdriver, Digitech preamp overdrive from the 70's (can't remember the model number), Ibanez TubeScreamer plus others. I would love to try the fulltone OCD. So far, I love my Bad Monkey's flexibility and transparency, even though I mostly use a BBE Boosta Grande clean boost to push my EVJ 1/2 stack over the top. Great amp, btw.
