I play some older Prog. material (Genesis, Yes, etc.) and use a 12/4 double-neck. I use a G10 for the guitar and another for the bass. Recently while rehearsing the 12-string signal seemed to drop completely and the bass sounded very strange. What happened was that the bass signal jumped from my G10 unit going into my bass pedal board over the the B10 unit connected to the guitar pedal board. I plugged each wireless back into their appropriate bass unit, took them back out, plugged them into the appropriate instrument and all was well. A few minutes later the guitar dropped again as the bass took over the guitar unit and went back in the guitar pedal board.
Thanks
