Buying Guide

• 1Check the truss rod adjustment — bass necks take more tension than guitar necks and are more prone to developing bows.
• 2Test the electronics with the bass plugged into an amp. Active basses should have a fresh battery for testing.
• 3Inspect the nut slots — bass strings can wear deep grooves that cause buzzing on the first few frets.
