In the words of JHS Pedals:

The JHS Hard Drive is the first attempt in our companys 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 weve released so far.
