Re: Improving fret access - strat lower horn
Take the body apart, take it to your local hardwood store, and have them plane about 1/4" off the back.
Of course, due to the vibrato system, it's not that simple. But there is lots of validity in the basic idea IMO. The original Fender prototypes, and very early production Esquires were 1-1/2" thick. That was Fender's original design. But early on after some trials by working musicians, and appearances at trade shows, it was decided to make the guitar a little bit higher class, so it didn't seem
quite so cheesy as the thin-bodied, black, cheap pine guitar that it was. This was done by giving it an ash body with a translucent finish, and by making the body more substantial by adding 1/4" to the thickness. In other words, Fenders were designed to be skinnier, and were made as fat as they are
for strictly cosmetic reasons. The thin body made a return later on "student" models like the Duo-Sonic and Musicmaster (and later the Mustang, Mustang Bass, and Musicmaster bass). Because of this, these models offer significantly better upper fret access than the standard thick-bodied Fenders (though the short scales really cram the frets together up there).
Also, most don't notice this, but G&Ls, the instruments Leo Fender stated were the best he had ever built, use the thinner body. As a result, they are easier on the back (shaves 1/6 off the weight of the body - over 5/8 lb. from an average 4 lb. 1-3/4" body), and they allow more comfortable upper fret access. So, later in life, when he had a more established reputation and the freedom to have more creative control (no need to worry about his instruments seeming cheap - bolt-neck guitars had already caught on big time), he went back to his original idea of the thin body.
