Make major mayhem with this crunchy pedal voiced for metal.

The Seymour Duncan SFX-04 Twin Tube Mayhem is a distortion pedal with a high-quality guitar preamp that includes a built-in boost. Using a duo of premium, mil-spec, subminiature, USA-made Phillips-Sylvania 62051 pentode tubes, the Seymour Duncan Mayhem is a great effect pedal for old-school metal, nu metal, thrash, death, and doom.

The Twin Tube Mayhem pedal has a high-plate voltage and 100% vacuum tube signal path that allow the tubes to operate at their full potential and provide maximum dynamic range. The SFX-04 Mayhem pedal achieves additional gain with a high-voltage, low-noise, and discrete Class A input stage. The solid state input stage increases the resistance of the Mayhem stompbox to microphonic feedback, resulting in maximum dynamic range, the most gain, and the heavy tone you'd expect from a great tube preamp voiced for metal.

The Seymour Duncan Twin Tube Mayhem distortion pedal also features user-selectable 4dB or 8dB boost for pre-setting rhythm and lead levels. The Mayhem distortion pedal uses true bypass switching and has a fully encapsulated toroidal transformer for quiet operation. Its rugged, heavy-duty steel chassis provides exceptional durability.
