This biscuit bridge style resonator guitar pickup successfully captures the sound coming off of the cone itself. The unit is composed of a replacement bridge with a thin element laminated into the biscuit, but the element also extends down onto the cone itself. The system is passive and requires no battery. Installation instructions included. Developed and produced by Elderly Instruments resident resonator guitar guru / repairman, Steve Olson. Conetone "Electric Biscuit" Resonator Guitar Pickup
