Seymour Duncan SFX-04 Twin Tube Mayhem

application

High-quality guitar preamp with built in boost. Uses a duet of premium, mil-spec, subminiature, USA-made Phillips-Sylvania 62051 pentode tubes. Great for old school metal, new metal, thrash, death and doom.

description

The high plate voltage and 100% vacuum tube signal path allow the tubes to operate at their fullest potential and provide 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 is maximum dynamic range, the most gain, and the heaviest tone your expect from a great tube preamp voiced for metal. Also features user-selectable 4dB or 8dB boost for pre-setting rhythm and lead levels. True bypass. Fully encapsulated toroidal transformer for quiet operation. Heavy duty steel chassis.
