Recently the pickguard on my custom electro-acoustic gave way and I removed it. The pickguard was glued to a little angle piece screwed to the end of the neck and this glued joint failed while I was playing. (Clearly I have strong finger pressure!) The pickguard tilted up around the angle bracket attached to the side of the guitar. I can play without the pickguard but I think the guitar looks nicer with it in place. Yes, I can re-glue the pickguard to the angle piece but I think there is a fault in the design. Pickguards on other guitars like Gibsons seem to be supported against finger pressure by resting on a collar surrounding the pickups. Unfortunately my pickguard is cut away around the pickups. I could get another one made up which only had cutouts around the central screw at the side of the two pickups, so that it could rest on the pickup collars. But what can I do with the existing one? Seeing as I would always play the guitar electrically away from home, the acoustic sound is not that important. Would a piece of rubber, say, jammed between the pickguard and the guitar surface be a bad thing? Would it affect the sound drastically? What sort of rubber, or other material, should I use? Otherwise I can see the glue giving away again in another ten years’ time!
