Analogue overdrive effect pedal for electric guitar that re-creates the circuitry of a Supro lamp amp and includes an actual output transformer because the real tone of a genuine Supro amp is based on the unique phase inverter design, Class A power amp section and the magnetic saturation that occurs via the old-school transformers found in these vintage tone machines. It offers a greater range of gain, dynamics and natural compression than the Tube Screamer, Klon or any of their many derivatives. The pedal sports a simple control layout with Volume, Gain and Tone knobs as well as a toggle switch to select between the different windings of the custom, multi-tapped output transformer – either for high-headroom BOLD sounds, or more compressed, high-gain RICH tones. It also offers a TRS port for expression pedal control of the GAIN knob for setting the maximum value, while a user-adjustable, internal trimmer sets the minimum gain setting. The pedal has an anodized, brushed-aluminium enclosure, 9V battery or AC powered operation (battery is included), rear-mounted metal jacks and studio-friendly, noiseless true-bypass switching. Dimensions: 80 x 80 x 125 mm. Weight: 0.5 kg.
