[quote name='E sharp' post='846749' date='May 24 2010, 05:50 PM']Early graphite necks could warp , as graphite has a memory . Steve Smith , who used to work with Bernie Goodfellow , fretted the Stingray for me (it was originally a fretless Modulus neck) , and told me that molecular memory was the reason why a few early carbon necks warped .[/quote]
Molecular memory applies to something that has been bent into a form that is different from its original state. A graphite neck is molded out of a resin/fabric composite. There isn't preexisting state for the molecules to bend back into. The fabric conforms to whatever shape the mold is and gets held in place by wet resin. The only exceptions to this form of construction are some of the Moses necks which are made mostly out of carbon dust impregnated resin and can be subject to movement with temperature extremes. But they're still formed from a mold like the other necks. (The Moses Steinberger necks are pretty good though, much stiffer.)
I understood that calculating the right recipe for sufficient stiffness in the phenolic fingerboard was tricky. Mistakes don't become apparent until long after the bass has been set up and sold.
Status, Modulus, Alembic and Musicman have all had well documented issues with this. Yes...even Rob Green is human!
