May 2013 blank1 (Page intentionally left blank). May 2013 EDITORIAL Finally we meet again his issue of Sustain took longer than usual. Indeed, preparing T a specialized magazine for a de- manding readership is no child’s play, and that is the way we like it, even if putting everything together takes a couple of extra months. In this issue we have, as always, a little bit of everything mixed in. Research, work- shop techniques, innovation, reviews of lutherie books, the answers to our read- er’s questions, and even a touch of humor provided by luthier Alejandro Baccaglioni, telling us about the real customer com- ments heard in his workshop. I loved the one made by a customer complaining about his fretless bass playing out of tune. I have a piece of (probably) bad news, though. The intern quit last week. He said he wanted to work for a big corporation producing a fashion magazine or some- thing. He said he thought of me and of our readers as a bunch of nerds. “We are a bunch of nerds”, I answered.

An electric guitar body has a com- pletely different process of sound gen- eration, leaving the big and rounded shapes behind and introducing convexi- ties, concavities, horns, recesses, and whatnot. Building an acoustic body in such convoluted shape would require special templates and some tight bend- ing of the instrument’s sides. The third (potential) problem is related to ergonomics. In order to project as expected, a classical guitar’s soundbox has to have a certain depth.
