I also posted this question on the Acoustic Guitar Magazine forum. Those of you who look at both, please bear with me. Thanks.
I'm about to make my first classical guitar. I would like to use my dreadnought fixtures if possible (Fox bender, forms). What is the history of this large a shape for a classical? What are the pros and cons? Should I bite the bullet and make new fixtures? This will be used by my 25 year old grandson for fingerpicking contemporary music, not a "classical" player. He would probably appreciate 14 frets clear of the body, but with nylon strings, I suppose I should stick with 12. I just ordered "Acoustic Guitar: The Composition, Construction, and Evolution of One of World's Most Beloved Instruments" by Richard Johnston (and Frank Ford) which I hope will shed some light on this topic.
I did see an ad in AG Magazine by Phoenix Guitars for a 14 fret, OM size nylon string guitar with cutaway and slotted peg head ("The perfect guitar for jazz and fingerstyle"). That sounds exactly like what I would like to build. It also looks like it has an additional sound port in the side.
