I have always made a high proportion of 640 instruments as they sound great and the earlier instruments have encouraged guitarists to order one. 630 has not been so popular but recently I have had a few people asking and seen some discussions online about where to get a 630 guitar. It seems there is a scarcity of quality short-scale instruments and players are forced to buy mass-produced products that are often made in China under an American name. Ordering a short-scale from a maker one trusts should be an obvious option but for some reason guitarists are nervous about how it will turn out.
I have a smaller mold made by my teacher for short-scale guitars that I have never used and so I thought that I would make a 630 scale and see if there is a serious market. The top is very nice and stiff and the wood is special as I decided not to use Indian rosewood for this one.
