About the Guild M-20

The Guild M-20 has been in Guild's lineup since 1963 — over 63 years of continuous production, which speaks to how well it has been received. Guild has been building instruments in the United States since 1952. You may also see this listed as "M-20", "M20" — they refer to the same instrument.

Buying Guide

  • 1Check the neck angle by looking at the action (string height) at the 12th fret. High action may indicate the top has bellied or the neck needs a reset.
  • 2Inspect the bridge for lifting — even a small gap between the bridge and the top is a significant repair.
  • 3Tap the top gently — a well-seasoned acoustic top will sound resonant and lively, not dead or muted.
