Hi all. Have been using my G50 wireless with guitar for many years, on weekend i used it in another band plugged into a bass guitar. Sound was fine, however it used lots of batteries for the night. Started with a fresh set of batteries in transmitter, display on body pack indicated 8 hours of runtime remaining, however at end of 1st set was indicating low battery. Replaced battery for 2nd set and the same thing occurred. Wondering if this is a common occurrence using these for bass guitars, or if it has something to do with the bass having active pickups, or if it could have just been a dud pack of batteries. Used it the following night back in guitar and got through entire night on single set of batteries, still showing more than 4 hours remaining. Anyone else experienced a similar scenario?
