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.36% — somewhat different

The Vertex Steel String Supreme SRV (Slight Return Edition) is a variant of Vertex's Steel String Supreme preamp/overdrive, itself based on serial number 001 of a Dumble Steel String Singer amplifier, with an EQ voiced toward a bigger low-end snap and brighter top-end chime associated with Stevie Ray Vaughan's playing. Active EQ plus Bright/Deep and Rock/Jazz switches add tone-shaping range beyond the standard Steel String Supreme. It covers everything from subtle clean fattening and compression to full overdrive, works equally into a tube amp or direct into a cab-sim/IR loader, and uses true bypass switching in a rugged steel housing. The black-and-white colorway and vintage chicken-head knobs echo SRV's actual Dumble amplifier.
The Vox CT-03BT Cooltron Brit Boost is a battery-powered boost pedal built around Cooltron technology, running a real 12AU7 preamp tube at safe low voltages to preserve authentic tube dynamics and harmonics without external power. Controls include a Treble Boost/Full Range Boost switch, Gain, Tone, and Volume, with true bypass switching. Treble Boost mode emphasizes upper-midrange and treble frequencies for a classic British chime, while Full Range Boost adds low-mid and bottom-end content, useful for pushing an already-driven amp into heavier overdrive.
