Buying Guide

• 1Play the guitar unplugged first — if it resonates and sustains well acoustically, it'll likely sound good amplified.
• 2Check the frets for wear. Flat spots and divots mean a fret level or refret may be needed ($200-400).
• 3Plug in and test every pickup position, and roll the tone and volume knobs through their full range to check for crackling.
