What is this stuff? Some kind of new additive for gasoline? Is this anything like "luthite"? I'm wanting to have a fretless neck built for one of my Jazz basses and I was originally thinking of Ebony for the maximum mwah-factor. But it seems as though a phenowood board is what Joe Zon and a host of other top builders use to great success. I was going to call Warmoth to see if they would consider using this phenowood but after reading the thread about how they aren't real flexible I may just put up a post to see if there are any builders that would do a Fender-type neck (going on a Fender Jaco Sig.)with some options...like graphite, flat profile, phenowood, lined board at around 2-2.5 pounds.
