I am having some trouble with consistency using my Baggs DI Venue tuner. When I'm on stage and kickdown on the mute/tuner function it works for a while (three or four times after songs) but towards the middle of the set it stops working/lighting up and I cannot use it to tune. After reading some posts I see that other people are having same problems. I didn't discover any solutions reading the posts. Anybody out there with any solutions? Is this a design flaw?
