I've been thinking about getting an SX and taking out the frets on the upper half of the neck. The problem is that, if I just take out the frets and fill them, I will have to compromise on the action, since making it high enough not to buzz on the fretted part would make the action on the fretless part too high. The solution, I suppose, is putting some flat material on the fretless part of the neck to raise it up to the height of the frets. But what material? I don't want metal, because I want a more traditional fretless sound. What about wood veneer (possibly a few layers)? Would this wear way too quickly? Anyone here ever done this before?
