 Much like a Stratocaster, the three pickups are selected with a five-way switch.Signal from the pickups passes through the tone controls, followed by an op-amp based buffer preamp, or unity gain buffer, which is designed to prevent signal loss due to capacitance when long cables are used.From the preamp, the signal could be routed via a mini-toggle on the guitar's face to pass through a Y-cable to Garcia's effects rack, and then back into the guitar.
