MXR CAE Boost/Line Driver
MC401
The Boost/Line Driver provides up to +20dB of ultra-clean boost to rejuvenate the sparkle, punch, and brilliance of your sound.
This pedal can be powered by a 9-volt battery, a Dunlop ECB003 9-volt adapter, or the DC Brick, Iso-Brick, and Mini Iso-Brick power supplies (not included).
The Boost/Line Driver is simple in design but superbly effective in solving a variety of mismatched line level and signal conditioning problems that can occur when combining effects. The MC401's circuit design has been used for years by CAE in the world's best guitarist's rigs to remedy these problems and rejuvenate the sparkle, punch, and brilliance that can be lost. It can also be used as an ultra-clean boost (up to +20dB) for solos or to drive effects for more dynamics and sensitivity.
