Does anyone out there know if anyone has ever produced a carbon fibre bass? I have seen an aluminum bass, which sounded like a dumpster with strings, and recently saw a fiberglass bass in a music store. I don't know who made it. The reason that I ask is that for my birthday last year, my wife bought me an Adamas Melissa Etheridge Signature model (6 string guitar). The top plate consists of .030" thick sheet of birch (strange choice of tone wood) sandwiched between two .005" layers of carbon fiber. The eveness of tone across the entire range is unbelievable. This guitar has replaced my carved arched top (Heritage Sweet 16) as the instrument of choice for my guitar gigs. I have been playing guitar for 56 years, and have played everything from a $10 Silvertone to a $50,000 Benedetto Cremona, and believe that this is probably the finest guitar that I have ever played. I realize that comparing basses and guitars is comparing apples and oranges, but this instrument has made me a believer in carbon fiber technology. Given the variability (and shortage) of wood, there just might be a place for it basses.
