EMT® 250 Classic Electronic Reverb Plug-In.
Iconic lever-driven digital reverb & modulation
effects unit.

Still regarded as one of the best-sounding reverb units ever made, the EMT® 250 Classic Electronic Reverb plug-in for UAD-2 and Apollo interfaces is a faithful emulation of the first digital reverb/modulation effects unit introduced in 1976.

The EMT 250 continues to leave an immeasurable mark on record-making history in the hands of studio legends like George Massenburg, Bruce Swedien, Daniel Lanois, Brian Eno, and
Allen Sides.

Now You Can:
  • Track and mix with the only emulation of the EMT 250 reverb unit, fully endorsed by EMT Studiotechnik GmbH
  • Dial in lush delay, phasing, chorus, and echo effects
  • Add distinctive space and depth to drums, guitars, and vocals with the same algorithm found in the original hardware
  • Harness plug-in-only features including Dry/Wet Mix, Wet Solo, and Hard bypass

Used on Countless Classics
The EMT 250’s distinctive clear and open reverb sound has appeared on countless records, including Prince & The Revolution’s Purple Rain, Elvis Costello’s Spike, and modern classics like The Red Hot Chili Pepper’s Stadium Arcadium.

Exclusively endorsed by EMT Studiotechnik
Designed in conjunction with EMT 250 designer Dr. Barry Blesser, the UAD plug-in version uses the same algorithms found in the original, extremely rare hardware. The EMT 250 plug-in was modeled from Allen Sides’ “golden unit” EMT 250 that resides at the legendary United/Ocean Way Recording.
With Unison Technology

Added Versatility with New Features
The EMT 250 plug-in goes beyond the original hardware, adding modern, workflow enhancing features like Dry/Wet Mix, Wet Solo, and Hard bypass. With these useful additions, the EMT 250 plug-in is even more powerful than the iconic hardware.

    (James Bay, Kings of Leon, Tom Waits)

    The EMT 250 plug-in is amazing. It’s all over Norah Jones' record. I used it on every song, it's that good.

    Just Blaze

    (Jay-Z, Saigon, Kanye West)

    "The modeling [was] done so faithfully to the original unit ... I’m a really big fan of that [EMT 250] plug-in."

    Andrew Scheps

    (Adele, Red Hot Chili Peppers, The Duke Spirit)

    "I use the UAD EMT® 250 Classic Electronic Reverb Plug-In reverb because it's such a specific sound, and that plug-in really does capture it."

    Joe Chiccarelli

    (Jason Mraz, Beck, The Strokes, Morrissey)

    The EMT 250 works great on snares. Keep it short and tight to add some dimension, or use the four-second range with full pre-delay for ballad-type songs.

    Rik Simpson

    (Coldplay, Portishead, Jay Z)

    Forget any other plate emulation, the UAD EMT 250 could actually be the real thing. Deep, wide, and full of personality.

  • Ryan Hewitt

    (Red Hot Chili Peppers, The Avett Brothers)

    "The EMT 250 and EMT140 emulations [for UAD] are stunning. They're just absolutely phenomenal."

    Jeff Russo


    "The EMT 250 [plug-in] is the perfect reverb for vocals. Warm and perfect tails."

    Glenn Rosenstein

    (Ziggy Marley, U2)

    "One plug-in I’m particularly happy with is the EMT 250 reverb ... And UA got it right. I mean spot on."



    "When I first called this [EMT 250 plug-in] up, waves of nostalgia kicked in ... the EMT 250 does an outstanding job."



    "To take your reverb to the next level, [the EMT 250's] full, spacious sound adds an overlay of reality that many digital reverbs lack."

  • Reviewer


    "You can't go wrong with UA's plugs, and these three [EMT 250, FATSO and Trident A-Range EQ] are no exception."

    Jacquire King

    (Norah Jones, Tom Waits)

    "[The EMT 250] just puts this beautiful halo of space and sound around the voice"

    Ryan Hewitt

    (Red Hot Chili Peppers, The Avett Brothers)

    Now I have UAD on everything, and I'm using the EMT 140 and the EMT 250 as effects – It's so much easier.

    Paul White

    (Sound On Sound)

    "To my ears it [EMT 250] has a plate-like character but with noticeably less density ... very flattering to vocals ..."

    Paul White

    (Sound On Sound)

    "[Cooper Time Cube, EMT 250, or FATSO] ... for the real vintage character, I don't think UA have any rivals at the moment."

  • (Computer Music)

    "The [EMT 250's] sound is very lush, with some pleasant modulation going on and a dark tonality."

    (Computer Music)

    "[The EMT 250] only really has one sound. But what a fabulous sound it is! It has a 'magic' to it that few others can touch"

    (Computer Music)

    "[The EMT 250 is] easy to mix with & sounds 'right' on a variety of material — we tried drums, percussion, vocals, synths & guitars."

    (Computer Music)

    "When you factor in the EMT 250's five funky extra effects, it all adds up to one outstanding plug-in. Great Work, UA!"

    Charlie Clouser

    (NIN, "Saw" Soundtracks)

    "The EMT reverb [plug-in] instantly took me back 20 years. I'm so glad to have such musical-sounding tools."

    Reverb is the best thing about UAD for me
    by M. Kondracki(Sunday 28 August, 2016)

    The reverb plugins are really my favorite thing about UAD. They are so close to the real thing I feel like I'm in a world class studio using the original gear. A MUST BUY. Read More

    My Go-TO Reverb
    by B. Troxler(Tuesday 2 August, 2016)

    The EMT 250 quickly became my go-to reverb. I own other UAD reverbs including DreamVerb, RealVerb Pro, AMS RM16, Lexicon 224 and started out with a Waves convolution reverb. Not a bad one in the lot. However, the EMT 250 consistently delivers the quality of reverb to support the genera… Read More

    Look no further!
    by m. stephanson(Sunday 17 July, 2016)

    For pure, lush tails and a density that adds a flattering thickness, look no further! I have several heavy hitting verbs, but since I got this, it has been on EVERY session, and is a beautiful compliment to the sounds I am getting from Hofa, Altiverb, and etc. But pure magic on vox!

    I'm very happy.
    by R. Becerra(Sunday 17 July, 2016)

    Until now it was using realverb and not get that quality with other brands or plugins. I had doubts whether to add another reverb would not buy the same as already had. EMT250 sounds wonderful, perfectly heard through a dense mix with muchs instruments, creates a natural amplitude without… Read More

    This is the God of Reverbs. Don't you dare question me.
    by S. Householder(Thursday 23 June, 2016)

    This Reverb is magic. It makes vocals sound like echoey, gooey butter on soft toast with cinnamon sugar. Thats right I said it. soft toast. cinnamon sugar. Seriously. You put this motherf--er on your lead vocal, and BANG! Grammytime. Thats what it is. I put it on four lead… Read More
