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.

The Boss SD-1 Super Overdrive is a long-running and affordable overdrive introduced in 1981, built around an asymmetrical clipping circuit that distinguishes it from the symmetrical Tube Screamer family. The asymmetrical diodes clip each half of the waveform differently, adding even-order along with odd-order harmonics for a slightly grainier, more aggressive, and harmonically rich voice with a touch more body and output. It shares the mid-pushed character that helps notes cut through a band, but feels closer to real tube-amp breakup, especially when pushing an already clean amp. Players use it as a low to medium gain drive or as a boost stacked into a dirty amp or another pedal. Used by Zakk Wylde, Josh Homme, and countless others, it suits blues, rock, and metal rhythm and lead work.
The JHS Angry Charlie is a Marshall JCM800-voiced overdrive built around a 3-band tone stack just like the amp it emulates, convincingly reproducing that amp's warm yet searing character and boundless sustain into any rig. With the gain rolled back it turns surprisingly bluesy and vintage-sounding, and as gain increases it covers everything from Hendrix-style crunch through AC/DC-style rock grind to Van Halen-esque heavy saturation, staying full and defined throughout the frequency spectrum. It ranges from edge-of-breakup tones to alt-rock and grunge-approved heavier gain, retaining clarity and touch sensitivity even at aggressive settings. It suits rock, blues, and hard rock players wanting a genuinely amp-like, JCM800-in-a-box overdrive.
