I defretted this SX Jazz neck and then coated it in epoxy. I radius sanded it smooth to 2400 grit and it plays really well - I'm just realizing that I'm not a fretless guy. I'd rather put a fretted neck back on the body this comes from. I installed a Hipshot string retainer and replaced the nut with a Tusq one.
Here are the dimensions:
Total length: 33 5/16"
Width of the neck at the nut: 1 5/8"
Width of the neck at the 12th fret: 2 1/4"
Thickness of the neck at the first fret: 7/8"
Thickness of the neck at the 12th fret: 15/16"
Neck pocket: 2 1/2" wide x 3/4" deep (not counting the fingerboard)
Pre-cut holes for tuners: 1/2" in diameter
I installed brass threaded inserts and will include the bolts on the off chance that they match up with your neck pocket holes.
