Scott Antes AGP-14 Steel String "Orchestra (OM)" Guitar Plan

Designed by renowned guitar designer Scott E. Antes, the AGP-14 is a traditional OM (Similar to Martin® “Orchestra” Model) guitar plan. The Martin Orchestra Model (OM) is one of the most influential acoustic guitar designs ever created. Although the dreadnought eventually became Martin's bestseller, many builders and players consider the OM to be Martin's finest overall design because it balances comfort, projection, clarity, and responsiveness better than almost any other steel-string acoustic. This is a 25.4” Scale (645.16 MM) and similar to a Martin® OM.

These plans are printed at full-size (1:1 scale) on heavy white paper measuring 35½" × 23¾" and are printed in the USA. Each set is carefully folded to approximately 12" × 9" and shipped in a protective folder.

This edition is offered through Luthier Suppliers with permission from the Antes family.

About the AGP-14

The AGP-14 is often considered the "Swiss Army knife" of acoustics. Before 1934, the OM and 14-fret 000 were very similar. Martin later shortened the 000 scale while retaining the OM's longer scale, creating the distinction we know today.

An OM is famous for having:

• exceptional note separation

• clear trebles

• tight bass

• excellent sustain

• remarkable dynamic range

It excels at:

• fingerstyle

• flatpicking

• Celtic music

• blues

• jazz

• singer-songwriter accompaniment

Unlike a dreadnought, an OM doesn't overwhelm with bass. Every note stays distinct.

The detailed full-scale drawings cover every major component of the instrument and are intended for builders who already have a basic understanding of acoustic guitar construction.
