I noticed a weird rattling sound coming from inside my bass when I moved it around so I decided to open up the back panel and found that the preamp board inside is not secured to the body anymore. It was originally attached the the top of the cavity with velcro and now the glue has dried out on the velcro and the board has fallen off (velcro is still stuck on the wood). What would be the best way to secure it so it doesn't rattle around? I had tried a piece of tape where the glue was but that didn't work for very long. It didn't stick very well to the board. Is there any harm in having the board loose besides the annoyance of it rattling around?
