Acoustode - Vacuum Tube Preamp

The 'Acoustode' is an audiophile quality, vacuum tube preamp, pickup booster and buffer in a compact and easy-to-use pedal format. This tough little black box is specially designed to add warmth, clarity and richness to enhance the tone of acoustic guitar piezo pickups and microphones. It's transparency and musical sound quality also make it ideal for use with NS Stick, upright or electric bass, mandolin, fiddle, Rhodes or Wurlitzer electric piano, drum machines, lap steel guitar, in fact any recorded instrument signal will be benefit from being enriched with this preamp. The Acoustode is equally at home on tour or in the studio where can be used breathe life and add warmth to the sterile, clinical sound of digital recordings or sound cards.

The signal-path is based on a NOS subminiature triode 6111 tube - tube notch/lowpass filter and tube phase inverter to achieve optimum gain and tonal balance when connecting acoustic instruments to guitar combos or PA. These tubes were manufactured to meet the stringent MIL-E-1 specification for reliability and designed for long service life under conditions of severe shock, vibration (20,000G!), high temperature and high altitude. The subminiature tubes represent the pinnacle of tube technology and offer more consistent musical performance than the early NOS germanium transistors.
