I've borrowed a Shure wireless system (UT14 The Guitarist) from a friend who is selling it to see if it will handle my basses fairly well. My active instruments seem to overdrive it pretty bad. I've tried 3 different active basses, 4 and 5 strings, 1 active electric guitar, and 2 acoustics with active electronics. All of them overdrive it. It works just fine with passive instruments, but I don't play my passive basses much at all anymore. I've adjusted the gain and all that on the wireless itself as much as I can, but that doesn't help much to remedy the problem. Have any of you had this problem before? Is there anything else that can be done to solve this, or do I just hold out until I can afford a better wireless?
