Carvin is selling some of their beautiful neck through 8 string necks, hardrock maple and ebony board with a paddle head so you can make any profile you'd like. Add wings of your choice, sand, add bridge, tung oil and GO, even the nut is cut. $229
I'd add the Kahler 8 string bridge, onsale at Wammi world for $200
fret board radius is a little too round at 14"
scale length is a little too short at 27" but it will still present a great creative tool
