Description
The MXR M300 packs six distinct reverb voices into a compact, low-noise enclosure, giving pedalboard builders a single-slot solution for ambience that ranges from tight room slap to sprawling, wash-out shimmer. Stereo I/O means you can spread that reverb wide across two amps or a stereo rig, letting the tail breathe in a way mono pedals simply can’t.
Placement is flexible: run it late in the chain after gain and modulation for a conventional wet-signal-last setup, or experiment with it earlier if you’re chasing a more blended, saturated wash. Either way, the low-noise circuit keeps the effect from adding unwanted hiss even when you’re pushing longer decay settings.
Plug in an expression pedal and the M300 opens up a second dimension of control, letting you morph between two completely different reverb configurations in real time — think subtle plate for verses swelling into a cavernous hall for a solo, all under your foot. And when it’s time to switch off, the delay trails mode ensures the reverb tail fades out naturally rather than getting chopped mid-decay, which matters a lot live when an abrupt cutoff can break the spell of a held note.
- Six distinct reverb types in one compact pedal
- Low-noise, stereo-capable design
- Expression pedal input for blending two setting configurations
- Delay trails mode preserves natural reverb decay when bypassed
For players who want studio-caliber ambience without dedicating multiple slots on the board, the M300 delivers serious reverb depth in a footprint that won’t crowd out your other effects.
