High-quality vacuum tubes are only part of the key to a great-sounding tube preamp. Too often, inexpensive tube gear runs in â€œstarved plate mode,â€� 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.
The Twin Tube Mayhem also features a user-selectable 4dB or 8dB boost. This allows for lead and rhythm levels to be set independently. Voiced for heaviest rock tones, Seymour Duncan say that the Mayhem offers raw tube sound, thick distortion, and present low order harmonics. The Twin Tube Mayhem also features true bypass with gold relays, over 90 dB of gain, a silent switching circuit designed to eliminate pops and clicks, and a heavy-duty chassis with a nickel plated chassis and stylish â€˜chicken headâ€™ knobs. A 16-volt AC transformer is also included.
