Here's the parameters: $150ish for blues and rock, not too much coloration of tone, less than JCM 800 amounts of gain ( I already have a radial Tonebone hot british which I love). My guitars are a VOS LP jr. and a Jazzmaster. I want something to do light to med OD and add some sustain. I was thinking the Fulltone Fulldrive 2 mosfet. Any others? OCD v4? I've heard great things but the clips I've seen on youtube make me think it might have too much overlap with the tonebone. The fulldrive 2 seems like it might fit nicely between the amps own overdrive and the hot british. Opinions? Thanks.
