Resophonic Spider/Biscuit Bridge Active Pickup System
"Finally, a pickup that captures and reproduces the unique tonal character of your resophonic guitar. This simple and unobtrusive pickup (the size and shape of a small washer) captures that funky, throaty signature resophonic tone with unprecedented accuracy and resistance to feedback.
The Active Resophonic pickup fastens to the center of the cone in both 'spider' and 'biscuit' style bridges. It includes an impedance-matching endpin preamp for absolutely accurate sound into any instrument amplifier, direct box or mixing console."
Requires 9V battery.
