Good question. Back in the 80's Chandler used to sell scalloped maple necks with Explorer headstocks. I sold a couple from my shop. It was NO FUN scalloping necks in the shops. I sometimes used a round microfile to remove the wood, or later I used round sandpaper barrels. Either way was a lot of work, you had to be very careful not to hit the frets. Then drilled for the dots and glued them in. I charged stupid prices to do it, and thankfully the trend burned itself out. Is the Fender Weenie Marmsteen neck available scalloped?
