Acoustic Tube SA1 Pickup
The Tube was designed to provide a flat, true acoustic response for natural sound. It uses a Stack hum-canceling design and it's extremely feedback resistant. The impedance is lower than other passive acoustic pickups, so it can go straight into a variety of mixers, amps and PA systems. There's also a volume knob right on the pickup for quick and easy control of volume during performances. And installation is a snap! For use with bronze wound strings.
