I'm finding the distortion pedals I have lacking. The general issue is that they're noisy - I now have a Radial Bigshot EFX pedal to remove them from the general chain - and generally unable to produce a workable sound (to my ears). I have a Boss HM-2 and MZ-2 and an Ibanez TS-7 and DS-7. I'm happiest with the HM-2, which is on the floor, while the others on the shelf. They are guitar-oriented, so not sure if a tonal recalibration and get a bass-specific pedal will make the sound better or if that's just snake-oil. The further complication is that I'm playing upright bass, which might be a factor in my general dis-satisfaction with the distortion I'm getting. Being of limited-budget, I'm not really able to afford boutique pedals. Brands I can secure from my LMS: Boss, MXR, Line 6, EH, Digitech, Behringer (I know: ugh. but they seem to have a few decent products), and Rat. I will also, at this time, fess up to being generally unwise in the ways to differentiate between fuzz, overdrive, distortion, etc. Am I looking at two different pedals? What kind of sound am I looking for - part of me wants totally urban-renewal house-levelling wailing, part of me wants the grit of John Wetton on King Crimson's Red or the Pixies' Kim Deal. ted.
