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.

  • Adds a preset amount of gain with a single control.
  • Boost your signal for lead work.
  • Perfect for switching between guitars with unmatched output.

Power: Single 9 volt battery or Dunlop ECB-003 AC adapter (Not included)
