A booster pedal to give you a little more oomph needed to overdrive your amp or boost your tone for a solo.

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

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Amp

An amp is an amplifier used to boost the signal from a guitar and shape its overall tone and volume. It plays a major role in how a guitar sounds, influencing everything from clean clarity to natural overdrive and distortion, and is a core part of any guitar setup for both practice and live performance.

Boost

Boost pedals give your signal that extra push — perfect for cutting through the mix or driving your amp into sweet natural overdrive. Whether you want a clean volume lift for solos or a touch of grit to wake up your tone, a good boost adds clarity, punch, and presence without changing your core sound. Simple, powerful, and essential on any board, a boost pedal can turn a good tone into a great one with just one stomp.

Gain

Gain controls the level of signal amplification within a circuit, determining how hard the signal is driven into the next stage. Increasing gain raises the input level and can introduce overdrive, distortion, or fuzz as the signal is pushed beyond clean headroom.

It plays a central role in shaping tone, affecting sustain, saturation, and overall feel. Low gain settings tend to preserve clarity and dynamics, while higher gain settings create thicker, more compressed sounds commonly used in rock, metal, and lead playing.

Micro

Micro describes compact, small-format music gear designed to deliver full functionality in a reduced physical size. Micro pedals, amps, and effects are built to save space while still providing practical controls and usable tone.

They are popular for pedalboards, travel rigs, and home setups where space and portability matter. Micro gear allows players to build flexible, lightweight systems without sacrificing essential sounds or performance.

Pedal

Pedals are the tools that let you shape, colour and transform your sound, from subtle tone enhancement to bold, creative effects. Whether you are adding grit, space, movement or control, a pedal becomes part of your playing rather than just an add-on. Exploring different pedals is about discovering what responds to your touch and helps your sound feel more like your own.
