What is the difference between an A grade and a B grade set-up?

A B grade set-up does the playability work: truss rod, action at the nut and saddle, fret end filing, strobe-tuner intonation on electric guitars and basses, a basic clean-up and new strings. An A grade adds the rest: minor fretwork, lubricated tuners, the hardware off for a deep clean, a buff and polish, and the electronics cleaned. Each instrument’s price page lists both side by side.
