About the GK-5B Divided Pickup

Expanded Fingertip Control

Once installed, the GK5-KIT-B system works in complete harmony with the instruments standard pickup harness. Both outputs can be selected independently or blended using the three-way toggle switch. A three-way momentary switch activates two controls (S1 and S2) that can be assigned to various functions depending on the GK-compatible device attached. Similarly, while the GK volume knob adjusts synth level, it can also be used to continuously control a variety of assignable parameters. A handy LED lets you know when the GK5-KIT-B is receiving power.
