From the manufacturer:

A salute to the rare and highly collectible "Super Tube Screamer" from the 1980s, the Maxon ST-9 Pro+ Super Tube distortion pedal takes the basic design elements of the coveted vintage model and brings them into the 21st century.Loosely based on Maxon's classic "808" circuit, the ST-9 Pro+ distortion pedal offers a dedicated midrange control that varies the amount of midrange boost, creating powerful, fat, and heavy distortion sounds akin to a full-stack amplifier. A mode switch to select from two different diode types allows the user to fine-tune the Maxon ST-9 Pro+ effects pedal for use with single coils or humbuckers, while switchable 9V or 18V operation provides increased dynamic headroom and fuller frequency response.When you're ready to step beyond the standard overdrive, the Maxon ST-9 Pro+ Super Tube distortion pedal is the only choice for the discerning overdrive connoisseur.
