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. Shown only within a gear class, and only where there's enough evidence to be meaningful.35% — somewhat different

The Mad Professor Ruby Red Booster is a clean boost and treble booster pedal with Master, Boost, and Treble controls, plus an internal switch for a high-quality buffer in bypass mode. Boost sets the gain of the booster from unity up to roughly 40dB, high enough that the pedal begins to distort internally when cranked, letting it double as a light overdrive. Treble adds up to about 15dB of carefully tuned high-end boost with an optimized bass slope, and Master sets the final output level after the booster stage. It is a versatile utility pedal that functions as a regular boost, a treble booster, or a light overdrive depending on how the Boost control is set.
The Spaceman Effects Atlas IV is a boutique preamp and boost pedal, the fourth revision of Spaceman's Atlas design. It delivers a warm, harmonically rich clean boost that thickens the midrange and adds weight without markedly altering the underlying tone, and pushes a valve amp into natural breakup as the level is raised. It is built as an always-on preamp stage as much as a solo boost, hand-built in Portland, Oregon in Spaceman's limited-run format.
