Blended 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.

Citation/mention fame — how often this gear is cited across artist rigs and gear discussion.The JHS Brand New Overdrive Preamp (JHS 3 Series Overdrive) is a warm, rich-sounding overdrive with a focus on extra gain and distinctive low-mid frequency character, sitting warmer and less harsh than a Boss DS-1 or a classic Tube Screamer. A diode-clipping slider switch offers two distinct voices: a germanium setting that clips more of the signal for a softer, smoother, richer saturation at slightly lower output, and an alternate setting for a louder, clearer, more open tone. Dedicated Level and Gain controls dial in everything from a clean boost to a moderate, vintage-flavored saturation, working well as a foundation gain stage or stacked with more aggressive drives. It suits vintage rock, blues, and country players wanting warm, preamp-style gain rather than aggressive transistor distortion.
The ThorpyFX Heavy Water is a dual high-headroom boost, built after requests to release the boost side of the Dane as a standalone pedal. The right-hand side is that Dane-derived clean boost, with Output and Lows controls that thin the signal out or fatten it up while otherwise leaving the amp's character alone -- at modest settings a subtle always-on lift that simply makes an amp sound better. The left side shares the same controls but clips through germanium diodes for a grittier, warmer, more textured boost with a touch of natural compression. Each half works independently, and stacking both will smash the front end of a valve amp into full overdriven submission. Reviewers rate it among the most versatile boosts available, running from transparent tone enhancement to an outright lead screamfest, in ThorpyFX's exemplary aircraft-aluminium build.
