From JHS:
The JHS Hard Drive is the first attempt in our company’s fifteen-year history at a full-blown and respectable modern distortion pedal that is not based on a previous circuit or classic topology. In 2016, Josh had the idea to develop a circuit that covered the best high-gain distortion tones of the ’90s and 2000s, a sound that embodied the post-grunge alternative rock movement. We started by looking at pedals, then amps, and after exploring the typical paths of circuitry, we took a sharp turn and started from scratch. Eight years later, the pedal is finished and ready to take you to the next level. The Hard Drive goes harder and further than any gain or distortion we’ve released so far.
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.
Volume - Controls the overall volume of the pedal. Left is less, right is more.
Mid Freq - Controls which mid frequencies are boosted or scooped by the Mid control.
Drive (Distortion) - Controls the amount of drive (distortion). Left is less, right is more.
Bass - Controls the bass frequencies level. Noon is flat, left is cut, right is boosted.
Middle - Controls the mid frequencies level. Noon is flat, left is scooped, right is boosted. The frequency range is set by the Mid Freq control.
Treble - Controls the treble frequencies level. Noon is flat, left is cut, right is boosted.
Silent soft touch switching with a buffered bypass.
THIS PEDAL REQUIRES STANDARD 9V DC CENTER NEGATIVE POWER, CONSUMES 78mA, AND MEASURES 2.6" X 4.8" X 1.6".
