I have a Fishman Matrix Infinity pickup, the battery pack was held in place by adhesive but has recently come loose. Any ideas for how to re attach it without using a substance that would damage the guitar?
You can use velcro. They sell both sides and you can cut it to the right fit. If the glue on the back of the vecro isn't strong enough, you can always use your own glue to make it permanent. Its on the inside, so don't sweat it so much.
