MXR M133 Micro Amp Gain / Boost Pedal

The MXR M-133 Micro Amplifier Pedal is a versatile and practical tool for guitarists looking to add a simple yet effective gain boost to their rig. Its minimalist design, featuring just one control knob and a footswitch, makes it incredibly easy to use, but its functionality is far from basic. Whether you’re looking to enhance your lead work, balance the output between two different guitars, or maintain a consistent signal through a long effects chain, this pedal delivers.

One of the key benefits of the M-133 Micro Amp is its ability to add a preset amount of gain with the turn of a single knob. This allows for seamless transitions between rhythm and lead playing by simply engaging the pedal to boost your signal. The Gain knob controls the total output volume, giving you the flexibility to boost your signal for solos or when switching between guitars with different output levels, such as from a humbucker-equipped guitar to a single-coil guitar.

Another valuable feature of the Micro Amp is its ability to combat signal loss in a long effects chain. When multiple pedals are connected, signal degradation can occur, leading to a weaker tone. The Micro Amp resolves this issue by providing a clean and consistent signal boost, ensuring that your sound remains strong and clear throughout your effects chain, no matter how many pedals you use.

The pedal is powered by either a 9-volt battery or a Dunlop ECB-003 AC Adapter, making it easy to integrate into any pedalboard setup. The footswitch toggles between the amp being on or in bypass mode, with a red LED indicator to show when the Micro Amp is engaged. The simplicity of the controls makes it an ideal addition for any player who needs a quick and reliable volume boost without dealing with complicated settings.

In summary, the MXR M-133 Micro Amplifier Pedal is a compact yet powerful pedal designed to enhance your tone and keep your signal strong. Its straightforward design and versatile applications make it a must-have for guitarists who need reliable control over their volume and gain.
