The Vertex SSS SRV Steel String Supreme Slight Return Version is a professional-grade overdrive/preamp pedal inspired by the rare Dumble Steel String Singer #001, known for shaping the tones of legends like Stevie Ray Vaughan, John Mayer, and Eric Johnson. Housed in a rugged steel enclosure, this pedal offers a fully analog, two-channel preamp circuit with a versatile gain structure—ranging from clean boost to thick, harmonically rich lead tones. Designed as a true "amp in a box", it's suitable for use in front of a tube amp, with a cabinet simulator, or direct to a mixing board. Controls include Output (first gain stage saturation), Gain (drive level), Filter (midrange focus), Fat (adds low-mid presence), Clean (blend between clean and driven signal), and Level (master output), as well as Bright/Deep and Rock/Jazz switches for further tone shaping. The active EQ and voicing switches provide extra clarity, punch, and midrange definition compared to earlier versions. The aesthetics reflect SRV’s iconic amp styling, and each unit is crafted with precision in California. Though this exact version doesn't have direct notable users listed, its sonic DNA is deeply tied to the sounds of SRV, Mayer, and Johnson.
