Overview

The MXR Distortion+ is one of the original distortion pedals, a simple two-knob design that has been shaping guitar tone since 1979 and continues to deliver a distinctive, musical distortion character. The Output and Distortion controls are all that is needed to dial in a range of tones from a gritty, low-gain crunch to a thick, compressed sustain with plenty of bite. The circuit uses a single op-amp into germanium clipping diodes, producing a soft-clipping distortion that is smoother and more dynamic than many modern hard-clipping designs. At lower distortion settings, the pedal produces a warm, slightly compressed crunch that retains excellent note definition and responds well to picking dynamics. As the distortion is increased, the sound becomes thicker and more saturated while maintaining a characteristic brightness and edge that helps the guitar cut through a band mix. The midrange emphasis in the voicing ensures that the signal remains present and focused even at higher gain settings. The compact MXR enclosure is road-proven and takes up minimal pedalboard space, and the pedal's simplicity means there is virtually nothing to go wrong. The Distortion+ is a classic choice for rock, punk, and alternative players who appreciate a raw, unprocessed distortion sound with genuine vintage character. The two-knob design means there is no tone control for fine-tuning the frequency response, which limits the ability to adapt the pedal to different amplifier and guitar combinations.

The MXR M104 Distortion+ is a pillar of pedalboard history, and for good reason. Its signature sound"defined by germanium clipping diodes"occupies a unique space between a fuzzy overdrive and a hard-clipping distortion. Unlike modern high-gain units, the 'D+' offers a grainy, vintage texture that feels organic and highly responsive to your guitar's volume pot. The build is classic MXR: a rugged, compact enclosure that can withstand decades of abuse. However, players should be aware of its quirks. The output level is notoriously low; you'll often find yourself cranking the Output knob past 3 o'clock just to hit unity gain. Additionally, the lack of a dedicated tone control means your EQ is at the mercy of the pedal's inherent mid-forward, slightly rolled-off top end. While it might lack the versatility of a boutique multi-stage drive, its simplicity is its strength. It excels at pushing a tube amp into classic 80s hard rock territory or providing the foundation for a gritty punk tone. For its price point, it's an essential 'flavor' pedal that every serious player should experience. It isn't a 'do-it-all' distortion, but what it does"that warm, compressed, vintage crunch"it does with undeniable soul.
