The Jim Dunlop MXR M104 Distortion Plus guitar effects pedal is the easiest way to take your tone from flat to awesome. The setup couldn't be simpler to operate, with a tonal versatility on offer that will blow you away!

Classic MXR design

The MXR M104 first graced many top guitarist's pedalboards when it was first released in the '70s - most notably the legend that was Randy Rhoads - due to its simplistic layout and undeniably powerful output. This reissue is no different, with MXR going to great lengths to recreate the magic.

The two-control knob set up enables you to go from subtle overdrive to face-melting distortion. The Output knob controls the output level of the effect, giving you the option to create a gentle kick when activating the pedal or a bombastic smack in the face. The Distortion knob controls just how much bite you want to infuse the output tone with, anywhere from a gentle sizzle to outrageous wailing. Whether you're playing some stripped-back blues, cruising through some classic rock, or tearing down the walls with some heavy metal, all you need to do is dial it in and hammer down.

The pedal is equipped with True Bypass circuitry, so you can rest assured that when the pedal isn't engaged, your dry signal will remain pristine and free of colouration.

Robust chassis

As we've come to expect from the team at MXR, the M104 Distortion + is built like a tank, and ready for the stage or the road. Many will attest to the heavyweight prowess of their MXR pedals, and with one of these beauties in your arsenal, you can't go wrong. The pots respond smoothly, attenuating the signal cleanly and without unwanted pops or click, whilst the footswitch engages with a confident click. The stage-ready LED indicator guarantees maximum visibility in even the darkest of arenas. The pedal can be powered using a 9V battery, or a 9-volt AC adapter.

If you're looking to give your tone the boost it deserves, then follow in many a legend's footsteps and grab the Jim Dunlop MXR M104 Distortion Plus guitar effects pedal.
