I'm planning on doing some Jamerson-style thumping, and everyone says some foam muting down by the bridge is an important element of that. Easy enough for me to put a bridge cover on my P bass (already has holes for it) and stick some foam in there, but I was wondering about mechanically-operated alternatives so I wasn't stuck with just one tone. (And I did ask this Q over in "technique" re: palm muting, so that's definitely an option I'm going to work on.) Anyway, my old Ovation Typhoon had a spring-action bridge cover with foam, and my old Ovation Magnum had a slide-action mechanism to raise and lower the foam, and I hear Rics may have something similar. Does anyone know of an aftermarket foam muting mechanism I could install? I'm willing to drill a couple of holes in the body. Thx!
