I just got this cool guitar. After a couple of weeks of playing it, it started to emit a buzzing / ringing from around the battery drawer (not plugged) only near F#, G and G#. I "fixed" this by coating the battery in a thin layer of styrofoam and duct tape, but the noise would still appear from time to time. Is there a better solution? The slot is a bit big for the battery IMO, leaving room for this type of ringing in specific positions.
LE. specified the notes producing it and the fact that the noise is back, after an hour of playing.
