Volume, boost & expression effect pedal
Made in the USA, the WALRUS AUDIO DEFCON4 Preamp EQ Boost is an effects pedal combining a preamp and an equalizer. When the Launch switch is activated, LED 1 lights up and a booster is added to the signal.
Use the rotary potentiometers of the Low (IV), Mid (III) and High (II) bands to attenuate or amplify frequencies (the switches activate or deactivate each band). Activating the Launch function engages a 10 dB MOSFET booster (indicator 1 lit).
