The Vertex Effects Steel String Supreme Slight Return Version expands on the company’s venerable Steel String MkII, arming you with a full-fledged, D-style preamp. Loaded with 100% analog solid-state circuitry, this clean drive stompbox builds upon its more-streamlined predecessor’s features with the addition of an independent EQ section and five extra tone-shaping controls. Park the SSS SR in front of your tube amp to inject it with D-style character, plug it into your mixer or audio interface for vintage-tinged DI-ed tones, or use it to infuse your digital modeling rig with tube-like warmth and transients. No matter how you use it, the Vertex SSS SR will deliver the coveted sound that top-tier players like Eric Johnson, John Mayer, and an iconic Texas bluesman made famous.

An amplifier’s worth of tone-shaping controls

The Steel String Supreme Slight Return Version was designed to function as a full-blown preamp. Thus, it includes all the tone-shaping controls you’d expect from a full-featured guitar amplifier. This pedal inherits the Level, Gain, Filter, and Jazz/Rock controls from the Steel String MkII, enabling you to adjust your master volume, saturation, mid-shaping, and overall character. The SSS Slight Return Version takes it further, however. An Output knob determines your first gain stage level, adjusting the saturation on your guitar amp’s input. Fat tailors your lower midrange for extra thickness and body. Clean offers a parallel blend of your clean and effected signal. A 3-way Bright/Deep switch yields a treble boost in the up position, is neutral in the middle position, and has a bass boost in the down position.
