I know I might come off as crass and ignorant in posting this but -- Peavey was a damn fool for not continuing this process (wood neck and carbon fiber). I know Parker guitars did some carbon fiber sleeves for their guitars with a wood fretboard. I've played graphite necks (Modulus and Status), and to my ears I find them to be a bit too sterile for my taste. I've played a Modulus Genisis and loved the concept of carbon fiber centered necks.
However, the GV neck just has a resonance that balances very well with Peavey electronics. Peavey might've seen this process as a "just as good" cost-saving but, I really think they could have run the process and made it their own. Carbon wrapping has only gotten better since the G/GV inception.
I'm hoping to one day build a custom quilted white Millennium body around a G bass neck with all black hardware.
Edit: My only gripe with the GV was the cheap chrome Gotoh style tuners. The gold ones work for the Cirrus but, I prefer the satin black hipshot tuners on Cirrus bolts, Millenniums, and GV's.
