OK, I've been searching the forum for several days and still haven't found a clear answer to solve my problem. This is going to be an effects question so please be patient. I've recently purchased a Behringer UltraBass BX1200 to use as a practice amp and as an easily transportable unit for small functions. My problem is that, playing through this amp, everything extraneous is amplified. Just picking up the bass rings loudly through the speaker. When rapidly playing, a harmonic sets up that hums right through just as loudly as the strings I'm playing even though muting. The plus of this is that it is forcing me to develop an even softer touch and better muting techniques but it's getting frustrating and the better techniques aren't solving the problem. I can set the EQ on the bass and/or the amp to subdue the noise, but by the time I've brought the level down I have nothing left of what I'm playing but mud. With our group, I play through an Ampeg 350W head with 4X10 cab and when we practice at our group leader's house I play through a Fender Bassman. I do not have this problem using those amps, only with my practice amp at home. I have been considering some type of effects box to solve this, but am not sure which, if any, would solve the problem. Some I've considered are the Tech21 Bass Compactor, and the Boss LMB-3 Limiter/Enhancer. My Behringer amp otherwise has great tone, volume, features I'm looking for....... Anyone have any thoughts or expertise in this area??
