Last year I bought one of the Relay G90 wireless systems. I bought it simply to escape the tone coloring that analog systems usually did to bass guitars. The first several months were great. Excellent cable-like tone, no tone sucking, interference, etc. Lately, however, it's been an absolute pain to use live. During soundcheck the last several gigs, It ends up fizzling out as if it's being killed by some kind of interference, which unfortunately forces me to run through a guitar cable for the entirety of the show. I know that the Line 6 relay systems are supposedly resistant to any kind of radio interference, but having it fail to work ONLY at recent shows, while it operates perfectly at home or during rehearsals, seems like a rather unlikely coincidence. And the fact that both my guitar players use the same exact systems, and have never had any sort of problems. Just today I was told by my studio engineer that wireless systems that are more budget-friendly tend not to be as dependable in the long run. So is it a waste of money? Is there a system out there better suited for bass that doesn't completely kill your tone?
