Vertex Effects Steel String Supreme (Light Return) Overdrive Pedal

PRE AMP PEDAL: Produces tube-like tone from 100% analog solid-state circuitry while providing a D-voiced guitar preamp. STEEL STRING: 3-way Bright/Deep switch brings treble boost in the up position, neutral in the middle position, and bass boost in the down position. SUPREME SRV PRE AMP: The output knob determines the first gain stage level and adjusts the saturation of your guitar amp's input.
