hey guys, im trying to build a deep tuned guitar and just asking, if someone has a hint, how to accomplish that, i.e. what constructional elements influence the zero frequence most. i know, that lightness is an important factor to do so. the size of the box and the soundhole seem to be also a part of the equation. has someone of you build a guitar pitched between e and d and any idea how he have done that? john, i think what the guy in the video says is definitely generalizable or is at least meant as a try to characterize the quality of deep voiced guitars in general (probably the santos in the video would make a good blanca). ive heard two blancas which were around e and they both had something in common, im striving for. and i heard torres la leona in natura a few month ago and it had the same kind of character (and is pitched in d, i think and is a very thiny guitar with a tornavoz). stephen, im interested in building a deep tuned guitar and just asking if someone, who have built one/some, have an idea, how to accomplish that, since i think communication with professionals or experienced amateurs is a good way to learn something. i have heard a lot of weirdo customer anecdotes from luthiers and you and anyone who needs to deal with that kind of clientel have my heartfelt sympathy. echi, the two low pitched guitars that i have examined so far, have both very thin soundboards (something around 1,5-1,8mm) and braces, but are different in terms of boxsize and thickness/weight of the backs and sides. only one of them, a cypress esteso replica, is very light (1100gr with machines), very thin back and sides (under 2mm) and has a very small plantilla (350mm im the lower bout). but the other one weighs around 1400 gr., has a much bigger plantilla. so the mass of the soundboard seems to be the most important factor and the overall weight-boxsize-ratio seems to be also important, probably lower stiffness of the box also...
