Ok thought I would lay a little problem I have on you I have a bass that has a tone monster pre in it and when I use it with my nady 332 wireless,my wireless go,s crazy switching back and forth between a/b channels? When I use the pickup blend knob,my other basses with preamps in them work fine with the 332.so any ideas why this is happening? It's kind of a drag because this bass sounds badass,what could this issue be???
