I have a Blender with the FIshman modified GLM200 and a BP100 running through a stereo cable (upright bass). I just hooked it up recently (used to use only the transducer). I swear the new hookup was fine at first (but could be wrong) but noticed the second time I used it in this config that if I hit my open "G" string pretty hard, I get a clipping/peaking/glitchy type of noise - most of the other notes sound allright. However, if I bypass the blender (same cable - so its only the transducer when I do this), I doesn't happen. Here's the thing - if I turn down the transducer channel on the Blender, it stops. So its not the mic, yet it can't be the pickup since the pickup works fine without the Blender. I think I got rid of any/all mechanical noises on the bass's pickup mountings. Stumped....my only thought is that a) My cable is too long (20') - although I don't see how this could be the case if the cable works fine w/out the blender. b) Do the mic and transducer cables need to run through separate isolation plugs? I have them going through the same one. c) If there is some sort of mechanical noise on the bass that I missed - however I don't see why the noise would stop when I bypass the Blender then. Any help would be great- still waiting to hear back from Fishman on it too..
