The MC401 Boost/Line Driver from MXR is a potent volume pusher, taking your guitar's signal up by a significant notch! With up to 20dB of boost on tap, this powerful pedal raises the overall output of your rig, serving as the perfect driver for solos.

However, it's not just a one-trick-pony. While it may only boast one control, the MC401 also adds some crisp top-end to your tone as well as more mid-range punch. This offers a sound with far more definition and brilliance, which can help to compensate for the signal loss caused by large and complex rigs.

Place this pedal in your effects loop and you'll achieve a pure, unbridled kick of extra volume. However, this unit can also shine when used in conjunction with overdrive or distortion pedals, and when placed before them you can achieve a more saturated and harmonically-rich tone. Whichever way you decide to route the MC401, you'll always find it useful!

MXR

MXR’s first product was the Phase 90, released in 1972. Dunlop’s official MXR history traces the early line from that compact phaser to the Distortion+, Dyna Comp compressor and Blue Box octave fuzz—circuits that remain central reference points for the brand. JustPedals carries those classic families alongside the Carbon Copy analog delay, Micro Amp, Talk Box and bass effects. MXR’s range is deliberately broader than one effect category: compare the model number and version, especially where a classic circuit has later reissues, mini enclosures or expanded controls.

Boost Pedals

A boost raises signal level without deliberately creating a new effect waveform. Clean boosts emphasise level and headroom, while coloured boosts reshape bass, midrange or treble and may add mild clipping at higher settings. Placed before a gain stage, the extra level changes how that stage distorts; placed later, it can provide a volume lift if sufficient headroom remains.
