A booster pedal to give you a little more oomph needed to overdrive your amp, or boost your tone for a solo. The MXR Microamp can also compensate for differences in output between guitars without having to fiddle with amps settings, or simply act as an always-on booster that supplements your amp’s tone.

Here’s what MXR say about the Microamp M-133

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

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.

Power: Dunlop ECB003 AC Adapter or Single 9 volt battery
