One time about two years ago, I played at a rehearsal studio, through an SVT. Bass straight in, playing classic rock stuff. And, it was freaking fantastic. There was just a bit of crunch or bite to it that made everything sing when I raised my bass volume a bit, without fuzzing out and being lost in the guitars. So, not wanting to lug around a thousand pound tube amp, I'm asking — what stomp box, or multi-effect, have you found that can do this best?
