How long could I expect the battery in my luke3 to last? I understand it depends on usage, but when it goes is it like a light bulb, or will it fade until failure?
I'm not sure how long the battery will last, but I do know that you need to unplug the cord from the Luke III when you're not using it because if you leave a cord plugged in, it will drain the battery.
when i play live, i put a new battery inside the guitar. and when i just go to play with friends, i just keep a 2nd battery in my case... ( I do the same when i use my luke II )
Yes there are two trim pots inside. The one on the right adjusts boost level and one on left adjusts the volume of the guitar when the toggle switch is in positions 2 and 4
