hey. me and my guitarist recently rented a boss 1180, and thought we had the thing figured out. we recorded the gutiar parts no problem, but then when it came time to record the bass parts, we found the bass distorted very badly, even at low input levels and sensetivites. we tried turning down the mic on the mixing board we ran the mics through, tried turning down the amp, DIing the bass amp straight into the mixer. the only way we found we could avoid such distortion was the run the bass straight into the mixer (but even this distorts occasionaly), although I am relecutant the record this way and would much rather use my amp. any ideas as to what may be the problem?
