I just had a Lyric installed on my Griffin OM. It sound great! I am using it directly into a Fishman Loudbox 100.

But...the volume control keeps falling off when I adjust the volume on the guitar. And I am gentle while doing that. The double stick tape doesn't want to hold it.

Any suggestions? The installer suggested Elmer's glue as it won't harm the guitar. Good suggestion? Or does someone have a better idea?
