The GT500 is simply 2 pedals in one: The (Left) Booster/OD side of the pedal is a 100% discrete JFET circuit utilizing True-Bypass switching that can be used by itself or in conjunction with the Right Side of the pedal. It excels at Clean Boost sounds and has a tremendous amount of Input headroom to accommodate even the hottest Pickups, yet can be pushed into Overdrive/Distortion sounds via its Drive knob.
