I'm doing some research on them, for a friend of mine ... oh screw it! i can't resist to spill the beans my friend is currently thinking on doing custom builds entirely from carbon fiber as a standard option of his catalog , and to have less trial and error i come to you guys for some opinions and feedback Carbon fiber is a very strong and durable material for instrument, but it tends to sound very sterile and bodyless from what i've researched, would this be fixed with a wood tone block? or a core with more carbon layers on the inside of the guitar? Would you guys like a composite fretboard aswell? or a wooden fretboard like on normal guitars? if this goes as planned, say bye bye to Parker ... ... ... I mean it. PD: Francis is currently preparing of doing it, but it's not an option as of yet, those who have contacted him for quotes wait until i post here more info about the project. But don't worry, all i can say that 2010 will be a very busy year.
