I'm really interested in buying a SansAmp for a grindy, slightly overdriven tone that won't drop me right out of the mix as soon as I step on it. The Bass Driver seems to be the most popular around here (duh) but the Para-Driver interests me in that it has a mid knob, and I've heard terrible things about the Bass Driver scooping all of the mids (and I have quite a mid-heavy tone). The Classic also interested me with all it's seemingly easy-to-use switches, which I assume would allow for more tone shaping capabilities, yes? So which would you choose: the Bass, Para, or Classic, and why? Thanks, Graeme P.S. How much more expensive is the programmable unit over the other three I mentioned?
