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

Boost

A boost pedal does one simple thing brilliantly — it makes your signal louder, stronger, and more alive. Whether you’re pushing a valve amp into natural breakup, lifting a solo above the band, or adding a touch more presence to your core tone, a clean boost gives you extra headroom without changing your character.

Use it at the front of your chain to drive other pedals harder, or after your gain stages to raise volume without adding distortion. Subtle or powerful, transparent or slightly coloured, a boost is one of the most useful tools on any pedalboard — small box, big difference.
