We Like Deals!


Adding a preset amount of gain with just a single control, the Micro Amp is a great way to boost your signal for lead work or adjust between two different guitars with unmatched output (i.e. humbuckers to single-coils). It can also provide a permanent boost in a long effects chain where signal drop off is a problem.

Features

  • Footswitch toggles amp on/bypass
  • Red LED indicates "on"
  • Gain knob adjusts total output volume when micro amp is engaged
  • Power: Single 9-volt battery or Dunlop ECB-003 AC adapter (sold separately)
  • Tough, compact metal enclosure
