The JHS Hard Drive is a fresh approach to achieving high gain distortion in a pedal format, the Hard Drive includes cascaded gain stages and a hard limiting circuit, followed by a class AB amplifier section that drives a “sweepable midrange” EQ and Baxandall bass and treble controls. With its generous external controls, the Hard Drive lets you dial in everything from grinding tube amp crunch to a bona fide wall of distortion that can easily cut through any stage or studio mix.
