I play a little bit on the higher frets (past 12th) and like a fairly low action. I have a problem with two basses where the higher frets are really far from the strings and it makes it harder for me to play quickly down in that region. I usually set my relief between .011" to .016". At the first fret, the strings are about 1/8" from the fret crown, and at the 12th, it's almost twice that. I am wondering if the neck angle would help solve the problem.
