The MXR Custom Audio Electronics Boost/Line Driver is a simple yet highly effective pedal designed to address a range of mismatched line level and signal conditioning issues that can arise when combining multiple effects in a pedalboard setup. With its proven circuit design, the MC401 has been utilized by Custom Audio Electronics (CAE) for years in the rigs of some of the world's best guitarists to solve these problems and restore the sparkle, punch, and brilliance that may get lost in signal chains.

As a versatile tool, the Boost/Line Driver can function in two main ways. Firstly, it serves as a powerful line driver, ensuring that your signal remains consistent and clean when navigating through various effects pedals. This helps maintain the integrity of your tone, preventing any loss of clarity or brilliance that can sometimes occur in complex setups.

Secondly, the MC401 can be utilized as an ultra-clean boost, capable of providing up to +20dB of gain. This boost function can be applied to solos or used to drive other effects, adding dynamics and sensitivity to your playing. Whether you need a subtle volume increase or a significant boost for lead parts, the Boost/Line Driver delivers a transparent and pristine boost without adding any unwanted coloration to your sound.

With its straightforward design and high-quality components, the MXR Custom Audio Electronics Boost/Line Driver ensures a noise-free operation and seamless integration with other pedals on your pedalboard.

This pedal can be powered using a 9-volt battery, or alternatively, it is compatible with the Dunlop ECB003 9-volt adapter, as well as MXR's DC Brick, Iso-Brick, and Mini Iso-Brick power supplies (though these power supplies are not included with the pedal).

For guitarists seeking a reliable and efficient solution to maintain signal integrity and enhance their sound with a clean and powerful boost, the MXR Custom Audio Electronics Boost/Line Driver is an essential addition to any pedalboard setup. Its ability to solve signal conditioning problems and provide a transparent boost makes it a valuable tool for achieving a pristine and dynamic tone.
