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.

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.

Description
The MXR Reverb delivers six distinct high end reverb styles, each exquisitely crafted and tuned by the award-winning MXR design team. It all comes in a standard-sized MXR box with a simple three-knob setup and a hi-fi analog dry path with a massive 20 volts of headroom thanks to Constant Headroom Technology™. Each reverb style is as richly detailed as any found in the highest-end rack units and plug-ins, and all you have to do to step through them is push the Tone knob.
The PLATE setting provides a shimmering smooth wash of space that’s a go-to choice from the studio recording world. SPRING sets a new standard for truly authentic sounding reverb without coiled metal—a perfect recreation of the classic amp-based effect, with the Tone control taking you from dark vintage amp spring, through classic jangle, to bright surfy splatter. EPIC is a unique combination of multiple interwoven analog-tone delay lines and complex modulation—perfect for solos from that more shaded part of the lunar landscape. MOD throws down a plate-flavored spaciousness with richly organic modulation in the feedback path. The ROOM style adds subtle body and projection to your guitar tone at shorter decay times while longer decay times yield rich organic space that doesn’t wash out. PAD closes out the line-up with a unique combination of sub-octave + octave-up with echoes + "shimmer" + synth/organ modulation + reverb.
Connect a Dunlop DVP series volume/expression pedal to the expression jack to toggle and blend between two different knob setting configurations. The Reverb includes 100% wet mode, stereo input and output capability, and true relay or trails bypass.

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.
