I just reseaved my new SC bass, and it's awesome. There's just one problem: the luthier didn't have the time to install the upper (closer to neck) strap holder. So I'll have to do it myself. It's not a big problem, but I'd like to know EXACTLY what I'm doing before I drill any holes to my bass. So 1) Where should I place the strap holder for maximum balance on a singlecut? 2) Is it ok if I just drill a small hole and screw the thing in? Thanks!
