I have a 1981 Ric 4001 and I have a tough time getting comfortable on it. It seems I can't find a good place to anchor my thumb. The bridge pup cover extends out too far from the strings so I have to stretch too far. I've tried placing it into the pup cavity and resting on the pup itself but, my thumb kinda gets stuck in there. I've also tried the floating thumb technique but that is wierd to me as well. It just seems there is too much stuff on the Ric and it is in the way. Even if I use a pick I catch my hand on stuff. My Jazz is clutter free and the pups are a perfect place to rest my thumb. I was thinking of having a pup cover made that is flush with the rest of the body or buying one it they make it already.
