    My 11 mos old Boss Pedal tuner just quit working tonight! I Changed the batteries and still no response, no signal... Dead. Any one have this problem?

    I would try just a regular 9 volt power supply to see if it turns on if not could be a possible bad ground on the inside of the pedal

    playing bass since 2005
    the battery snap didn't work when I got mine either, I just use a power supply. The guitarist in my old band had this problem with his TU2 and resolved it by doing the same method
