I am having wireless issues also with the PGW, 3 different units. I have used Relay G10's all over the house even around wireless without issues but the PGW easily cuts out and is therefore useless in a live band setting. Had to plug an old Relay G10 in the PGW for it to work without issues. Had I know that the transmitter in the PWG was so bad I would have bought the PG and used the G10's. Now I have to do this after paying the extra money for the the wireless. Really disappointed. Line 6 (Yamaha) say they cannot reproduce the problem but I am sceptical. Buyer BEWARE. Either the Transmiter is different between the 2 bases or the placement in the PGW is causing the problem.
