HI, well its kind of a general problem, using different PA desks over the year in various practice rooms, but also if i DI at a gig it does this too.
Through my amp I have never had a low warning light.
I have an Epi EJ200ce with the Sonic EQ, when I plug and play through my marshall acoustic amp, the batteries last for ever
when I plug into a PA desk they drain more and I have to replace a LOT more often!
Why is this?
thanks
