I use this purple and yellow swirl guitar for upper fretboard
work, when I need to do some high harmonies or just have better
access to higher frets (namely "Squeakie", "To Counter" and
"Mosquito"). I took the neck off of a short scale bass, threw on
a new fingerboard, and cut enough slots for 29 frets. I also had to
fill in the 4 holes at the headstock, and redrill 6 smaller
holes for the machine heads.
