I'd like to have a mahogony body/figured koa top body blank made with the no-tilt neck pocket, recessed floyd routed & studs installed, & direct mount humbucker cavitys routed out, the leave the body shape & control cavities to me to finish.
In turn, I'd also want to have a 24 fret, 24 /34 scale mahogony neck with a nice ebony fretboard, ss 6100 frets, paddle headstock. The main thing is though, I'd want the neck to go flush with the end of the fretboard, like the Ibanez necks. I don't care for fretboard hangovers. Just my personal preference. I notice a slight loss of sustain & volume on the extended area's.
I'd have to have some dimension modifications on the blank though, my body style widens out at slightly over 15 inches at the widest point, & the upper cutaway extends nearly to the 12th fret of a 24 fret 24 3/4 scale neck. Then again, the guitar I'm modeling this after is a neck through.
Here's a pic of my neck through custom I designed & had built 11 years ago.
