The ATG-1 Auto-Tune for Guitar Floor Processor allows you to add all of the powerful Auto-Tune for Guitar features to virtually any guitar.
Guitars already equipped with Roland standard 13-pin output can plug directly into the ATG-1. Examples include 13-pin equipped guitars from Godin, Carvin, Parker, and Roland.
Other guitars require the simple addition of a hex pickup like the Roland GK-3 or equivalent. These pickups can typically be installed with no physical modification of your guitar.
