Maxon ST-9 Pro+ Super Tube Distortio n Guitar Effects Pedal

A salute to the rare and highly collectible "Super Tube Screamer" from the 1980's, the Maxon ST-9 Pro+ Super Tube takes the basic design elements of that coveted vintage model and brings them into the 21st century.

Loosely based on Maxon’s classic 808 circuit, the ST-9 Pro+ 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 ST-9 Pro+ for use with single coils or humbuckers, while switchable 9- or 18-volt operation provides increased dynamic headroom and fuller frequency response.

When you're ready to step beyond the standard overdrive, the ST-9 Pro+ Super Tube is the only choice for the discerning overdrive connoisseur.

Maxon ST-9 Pro+ main features include:

• Versatile overdrive based on the Super Tube Screamer
• Powerful, fat and heavy distortion sounds
• Two different diode types for versatility
• Switchable 9- or 18-volt operation for more headroom
