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.
Chase Bliss Automatone Preamp MKII is a fully analog preamp and overdrive pedal built in collaboration with Chris Benson of Benson Amps, combining the touch-sensitive character of the Benson Chimera preamp with variable diode clipping, switchable open or gated fuzz, and three mid-resonance voicings that can be routed before or after the preamp stage. As the first Automatone-series pedal, it pairs that analog tone generation with motorized faders that physically move to recall any of thirty stored presets across three banks. The result ranges from transparent boosts and edge-of-breakup tones to aggressive distortion and gated fuzz, with the rich harmonics and musical EQ Benson amplifiers are known for. It suits players wanting deep, amp-like preamp voicing with studio-grade recall.
