Yes. I have 2 Planet Waves covers - I think they are called 'Screaming Halt!'. They are currently sitting in my studio and are used as receptacles for picks/capos, etc (pity I don't smoke, otherwise they would have become ashtrays!). I found they worked well enough in rehearsal room situations, but no so well on-stage. The main problem was with my personal monitor (SRM 150) and the fact that I am a vocalist/guitarist, so the mic was in close proximity to the guitar and the monitor. In the end, I solved the problem by losing the monitor and moving to Shure in-earphones. They take a little getting used to but, in my view its worth it. I suspect there would not have been a problem with the soundhole covers if I didn't need a mic. Hope that helps.
