The GMF AT-1 soundboard transducer is the best way to amplify just about anything that vibrates. The AT-1 is designed to pick up vibrations from any acoustic soundboard be it on a classical guitar, violin, harp or even a piano.
The AT-1 pickup sensor is embedded in a natural Birch wood housing and includes an attached, 10 foot low noise double shielded instrument cable with a standard 1/4" male plug. Installation is very simple, just stick the pickup onto the soundboard with the included adhesive putty, and plug into your amplifier. The pickup can be easily removed for storage and reattached when needed.
The AT-1 can be used as the sole pickup or to augment built in pickup systems. All musicians would benefit from having one or more of these stick-on pickups as they are handy and useful tool and can get you out of a jam when the battery in your on board system decides to die.
