silly question, I am guessing not much I found this interesting fabric and thought about finding a cheap white pickguard and gluing it securely to the pickguard, then installing the pickups. Will this change the sound very much? Is part of the sound of the pickups, caused by reflections of sound from the pickguard itself? Those wouldnt happen with fabric covering the surface. I'm hoping it wont be a factor, I dont think it would be, but thought I would ask the experts here.
