MXR make some incredible pedals but oddly enough they have never really had many reverb pedals in their lineup. The M300 has 6 different reverbs available at your feet with three simple controls to get everything set up up nice and easy.

Six Models

Inside this compact pedal you have access to mericulously crafted Room, Epic, Plate, Spring, Mod and Pad reverbs that are all switchable with a push of the Tone control. Each of these models are controlled by a high quality digital chipset while the dry signal is 100% analogue not going anywhere near the digital tone path. This keeps your signal clean and clear.

Simple Controls

No one wants a pedal that takes ages to set up. Simplicity is key especially with things like reverb, that is why the MXR just has three simple controls. Mix which sets the dry/wet mix of the effect, Tone sets the feel of the effect rolling in more high end, the Decay control sets how long you want the reverb to last. Nice and simple to set up and get any tone you want.

Here’s what MXR say about the M300 Reverb Pedal

The MXR Reverb packs six distinct, exquisitely-crafted high end reverb styles into a Phase 90-sized box package with a simple three-knob setup, a hi-fi analog dry path, and an expression output so you can blend setting configurations.

  • Six meticulously crafted reverbs in one pedal

  • Dry path is 100% analog
  • Studio-grade low noise floor

Delay

A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.

From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.
