Power Attenuator

A Power Attenuator enables a player to obtain power-tube distortion independently of listening volume. A power attenuator is a dummy load placed between the guitar amplifier’s power tubes and the guitar speaker, or a power-supply based circuit to reduce the plate voltage on the power tubes. This is essentially a commercially packaged version of what Eddie Van Halen has done for years to achieve his famous “brown sound.”

Examples of power attenuators are:

  • Rockman Power Soak
  • THD Hot Plate
  • Marshall Power Brake
  • London Power Power Scaling circuit
  • Dr. Z Air Brake
