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 Tru-Fi Scream to Eternity is a Tube Screamer-style overdrive pedal built around TS808 circuit heritage, offered in Tru-Fi compact modern enclosure. Its Mode switch selects between Scream and Eternity voicings, with Eternity running as an open, buffer-less circuit for a more transparent feel. A Gain switch chooses between a Brown circuit with roughly 30 percent more gain and the classic 808 voicing, while Level and Tone controls shape output and brightness, and a separate Clipping switch toggles between the original diode clipping and an asymmetrical option for a different breakup character. Together these switches let the pedal move between the familiar mid-hump, tube-amp-pushing overdrive that Tube Screamer circuits are known for and a more open, less colored drive voicing, without changing pedals.
The Wampler TCD (The Compulsion Drive) is Brian Wampler's reimagining of the Fulltone OCD distortion circuit, offering Gain, a 3-band EQ (Bass, Mids, Treble), and Level controls, plus a Mode switch selecting between a traditional gain structure and cascaded MOSFET gain stages for a harder-hitting, more tube-like sound. Hidden Fat and Diode switches add further tonal options: Fat adds deep low-end warmth, while Diode shifts the gain profile via an added clipping diode for tighter, more saturated distortion.
