Hi!
Some pedals I've checked out and liked. I work at a store, so I get to try out all kinds of stuff.. sadly most of it low end...
Boss SD-1. Very cheap, eats some low end. Your basic average od.
Hughes & Kettner Warp. Γber metal! Good bottom (with Sub on) and a lot of distortion.
Anything by SansAmp seems to work thumbsup . They're versatile, but cost a bit..
Aah... but what do I know, I like metal
Cheers,
Jussi
