• This device adds a preset amount of gain, using a single control.
• With a guitar, this lets you boost your signal for lead work, adjust between two different guitars with unmatched output (i.e., humbucker to single coils), or it can supply a permanent boost in a long effects chain where signal drop off is a problem.
• Power: Single 9 volt battery or Dunlop ECB-003 AC adapter.
• Footswitch toggles amp on/bypass (red LED indicates on)
• Gain knob adjusts total output volume when micro amp is engaged.
