Seymour Duncan SA1 Acoustic Tube Acoustic Pickup
Designed to give a flat, true acoustic response for a natural sound. The SA1 has a stacked hum-canceling design and is quite resistant to feedback. Compared to other passive acoustic pickups, the impedance is much lower so it can go straight into a variety of mixers, amps and PA systems. The SA1 has well-balanced string response, so each string plays equally loud. And, if you prefer, there is an adjustment to favor the bass or treble strings. There is also a volume knob right on the pickup for quick and easy control of your volume during performance. The SA1 clips into place in seconds. Balanced for use with bronze wound strings. Not for use with nylon String guitars.
