Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

The Electro-Harmonix Hellmaster is a high-gain distortion pedal from EHX delivering extreme saturation suited to hard rock and heavy metal applications. The Hellmaster provides aggressive, high-gain character with a dense, compressed distortion voice and sufficient gain for modern metal rhythm and lead playing. As an EHX product in the heavier end of their drive lineup, it targets players who need a dedicated high-saturation distortion suitable for heavier genres without the boutique pricing of more specialized alternatives.

The JHS PackRat is a boutique multi-mode distortion pedal from JHS Pedals based on the ProCo RAT circuit, one of the most influential distortion pedals in rock and alternative music history. The PackRat includes a rotary mode selector that provides access to multiple historically different RAT circuit configurations, including vintage LM308-chip variants, the Turbo RAT, and other notable RAT iterations. Each mode calibrates the clipping character, gain response, and filter behavior according to the specific circuit variant it reproduces. JHS designed the PackRat as a comprehensive RAT-based distortion reference for players who want access to the full range of RAT circuit history in a single pedal. It suits classic rock, alternative, post-punk, grunge, and hard rock where ProCo RAT distortion is central to the sound.
