very, very good

the only thing keeping this pedal from being 5 stars is that there are cheaper pedals out there that offer more versatility, but this pedal is very good at what it does. I bought this in 2021 when it costed only $200 and it is still the most expensive pedal on my board, and it is worth the price even if I don't use it too too often. nevertheless, the tones that this pedal has, and the way that it works so well with any setup is a real testament to the dedication MXR put into this verb.

Great sounding reverbs

Love the sound of the reverb, you have tons to chose from. And the fact that it has buffer makes it even better.

Simple and great sounding

I wanted a good sounding plate and shimmer reverb with a simple interface, Reverb is one of those effects I like to keep simple and not have to many knobs or options. Went to my local music store and tried some pedals. This was it. All of the modes sound really good, especially the plate, which I think is the best sounding of them all. I really like the Epic and Mod mode as well, although I wished the Tone knob would change the speed and depth of the modulation (as it changes the octave up/octave down in Pad mode), but it's in a nice sweet spot of slow rate and medium depth of modulation and sounds great with volume swells, sending your trails into a warped region of space past by a small black hole. Analog Dry-through, buffered bypass for huge trails and those 20 Volts of constant headroom are the cherry on top of an instant classic by MXR, even with my Brothers Gainstage throwing it a huge boosted signal this guy keeps it clean and shiny. The only negative things I could point out are the lack of dedicated stereo outputs (i cant find angled Y cables to accommodate it in my pedalboard), the tone knob feels loose and rusty (c'mon MXR this is not a cheap unit...), and what I believe to be a design flaw by MXR - the power input is right next to the audio input so I cant use my flat right-angled patch cables because it obstructs the power input. I also would have liked preferred two switches to toggle between true-bypass/buffered trails and Wet+Dry/Kill Dry instead of having to do the whole number of unplugging the power to enter startup mode. But anyway i'm not messing around with those that much. Overall I'm pretty happy with it.

So good, I own TWO...

That's right, I loved the first MXR M300 Reverb I purchased so much, I bought another. Why? Because running a stereo setup and being able to dial in two different types of reverb that compliment the amp-cab combos they run on allowed me to sculpt dreamy sonic soundscapes. Being able to blend the dry signal (like in some on-amp reverbs) allows you to help pull back on the leash a bit when you're trying to maintain control over the base signal. However, if you're into the whole "lost at sea" thing with really washy reverbs, there are settings you can dial in with this pedal that can create other-worldly sounds. The more conventional plate and spring settings are absolute gold, MXR did an excellent job at capturing the nuances of these tried and true reverb modes. If you're looking for more synth-like sounds, you can leap across the divide and obtain a totally unreal effects that can hardly still be considered "reverb".

If I bought two, you should buy at least one.

It was my dream reverb. The main reason to change my multieffect to dedicated effect pedals 🥹

Since I saw the official commercial video on youtube and heard the pad setting I wanted one. It is top quality and easy to use. For me there is no better reverb pedal.

A must have

Definitely a must have. All digital, but gives the feel of analog. Spring setting feels 100% authentic. Pad setting is particularly cool; it gives really cool shimmery tail effect. I've mainly been using the Plate setting, and I couldn't be happier with the results. Truly authentic analog sound, extremely user friendly, and very versatile. Definitely love this one.

Great!

Controls are simple and great tones.

Awesome pedal. Until noise issue started

Bought this brand new in 2016. Sounded great with acoustic and electric guitar. Only gripe is the noise that this gadget started creating in my effects chain this year. I tried running this using an isolated power supply, separate power adapter etc but those aren't working. Any suggestions?

Awesome pedal with lots of choices.

The amount of versatility this pedal has is incredible, and all of the settings sound awesome. Works fantastically well through an FX loop and sounds killer.

Beautiful

Endless etheral pleasure in a guitar pedal. If you're looking for a david gilmour, spacey styled reverb, look no further. Comes with 6 different styles of reverb, all adjustable through the knobs.
