Looking at Line 6 wireless stuff. Heard the G10 and some other units were not "compatible" with active basses... 1 - What does that mean? 2 - Does the G30 suffer these limitations? I have an active bass MM Stingray and PJ Passive so i would like a system that obviously functions for both. The Wic ELF was touted as a good one but some threads seem to indicate high noise floor?
