neck is mahogany and wenge, fretboard is granadillo which is another rosewood substitute
This style of neck join has intrigued me for a while so i thought i would give it a go. some people make them longer to go under the bridge, and some dont. In this instance i didnt because i can still get another neck from the same blank. I think phil kings new bass has a similar idea but the neck extends all the way to the bridge and peeks through the top... that would have been a lot harder to do than this
