thank you for your answers
yes i had made this questions because i have heard a lot about tune the top, not all guitar, and i just try to understand this, as a builder i'm always try to know diferent aprouches and tecnics and this one i really dont see how can do a good top... well, in fact if you do all tops with one note , for example F, you will have all your guitars very near sounding of one of each other, even if everithing else will change and of course will change, it will be dificult you put always a bridge with the same pich for example.
Ryeman i thougth the same i din't saw diferences as well, that is the reason that i wish to have something more precise... not only the ear..
and to "tune" the top if you start with a top with G and wishes to hava one F i believe that you must take i+one big amount of wood to down one tone.. or not?
is something that i'm not see here????
I never had done this process, i just do like Romanillos teaches in hes book and works fine... but i never stop triyng to know other methods
