Seymour Duncan SFX 04 Twin Tube Mayhem Distortion Pedal

Capitalizing on the success of their previous stompbox offerings, Seymour Duncan have released their latest pedal, the SFX-04 Twin Tube Mayhem, a high gain guitar preamp that uses a duet of subminiature 6205 vacuum tubes and is voiced to evoke the heaviest sounds that define metal. High-quality vacuum tubes are only part of the key to a great-sounding tube preamp. Too often, inexpensive tube gear runs in ''starved plate mode,'' where the tubes function like clipping diodes and do not actually amplify. The Twin Tube Mayhem employs a fully encapsulated, toroidal transformer to achieve the high plate voltage required for true tube amplification and maximum dynamic range. Additional gain is achieved with a high voltage, low noise, discrete Class A input stage. The solid state input stage increases the resistance of the stomp-box to microphonics. The result, say Seymour Duncan, is maximum dynamic range, the most gain, the smoothest tone, and the low-order harmonics one expects from a great tube preamp.
