Throwing my cards in for the Genzler 4 on the Floor as the best fit for me. I've tried so many ODs its not funny, the dealbreaker for me was always the distortion in the low end - I want overdrive, not fuzz( to me, distortion is very different than OD). At first when I tried it, I was not impressed, but then I read Genzler's instructions carefully and have finally found what I am looking for. Their key is that the distortion path goes through a high pass filter (hpf) and low pass filter (lpf), then you can dial in distortion and clean to get the sound that you want. Each has a separate volume control, and the hpf and lpf only affect the drive signal. So I set the hpf at about 100 hz, and set the drive volume at about 1 o'clock and the clean about 12 o'clock - this meant that I could get OD breakup without fuzztones in the lower register, since I set the hpf to filter out anything below 100 hz (or whatever I wanted). I t works amazingly well - can even dial in a fair amount of distortion without getting "fuzz bass", which I hate. Kudos to Genzler.
