Question:
I am curious as to how a semi acoustic guitar is made? Specifically I am interested in the design of the Godin A6 model. (See at: http://www.lasido.com/godinmaster.html ) It states that the body is a light maple two chamber body. Do you start with a solid body and route two chambers before applying the top? Or do you construct it as you would normal acoustic guitar, by curving the sides, etc. Does the top use bracing as in regular acoustics? Also is there some sort of access to the pickup though the back of the guitar. If you look at the picture of the A6 there is no soundhole, just some slits upper left portion of the body. Are there any books, websites, articles, that might have some build plans for a similar style guitar?
Answer:
I don't know about the Godin specifically, but most makers start with a solid body, & route the chambers, then cover the top. Another way is to just cut the chambers out with a saw, & then cover both the top & back. Try www.mimf.com. Also go to deja-news, & search this newsgroup. Warmoth has a cutaway picture of their semi hollow Tele in the current Guitar Player in an ad. Most of these are made the same way-start with a solid body and rout away. I've seen some that have 2 large open cavities on each side of the strings. Ends up somewhat like an ES335 with a solid block in the center. The alternate method is more like Warmoth's where you route a grid pattern removing probably 50% of the material but leaving the grid on 1-1 1/2 centers to support the top. I don't think normally there is bracing. If you cut way almost all the material you'll need somewhat to support the top.
