What are the factory specifications for my U.S. PRS bass guitar setup?

  • First, once the strings are thoroughly stretched, tune the instrument to pitch. Repeat stretching and tuning the instrument.
  • Then, adjust the truss rod relief, and re-tune the instrument.

Using a capo at the first fret, measure the distance from top of fret to bottom of string while depressing the string at the 1st and last fret: Relief for PRS bass guitars should measure .4/64" - .7/64" (.1mm - .3mm) at the 8th fret.

Once the relief has been set, re-tune the instrument. The measurements for string height should be as follows (measure from the top center of the fret, to the bottom of the string):

 

Four String Bass

  • Treble side string height 1st fret: 1.2/64” - 1.8/64" (.5mm - .7mm)
  • Bass side string height 1st fret: 1.7/64” - 2.3/64" (.7mm - .9mm)
  • Treble-side string height at 12th fret: 2.1/32" - 2.6/32"  (1.7mm - 2.1mm)
  • Bass-side string height at 12th fret: 2.5/32” - 3/32" (2.mm - 2.4mm)
  • String height should escalate in value from Hi G to low E 

Five String Bass

  • Treble side string height 1st fret: 1.2/64” - 1.8/64" (.5mm - .7mm)
  • Bass side string height 1st fret: 2/64” - 2.5/64" (.8mm - 1mm)
  • Treble-side string height at 12th fret: 2.1/32" - 2.6/32"  (1.7mm - 2.1mm)
  • Bass-side string height at 12th fret: 2.7/32” - 3/32" (2.1mm - 2.5mm)
