Immerse Reverberator Mk II

Studio Reverb · 8 Algorithms

Eight studio reverbs. One pedal. No manual required.

Reverb algorithms masterfully crafted by Brian Neunaber. Built by Quilter Labs.

Most reverb pedals make you choose: one great sound in a simple box, or a wall of options buried under menus and a manual you'll never read. The Immerse Mk II refuses the trade-off. Eight rich, studio-quality stereo reverbs — each one tuned by ear, dialed in with real knobs, ready the second you plug in. No screens. No scrolling. No homework.

This is the Mk II — completely redesigned circuitry and upgraded algorithms over the original. The dry signal stays fully analog for zero latency and dead-quiet operation, while a high-quality buffered output sits exactly where reverb belongs: at the end of your chain. Guitar, keys, bass, vocals — it makes anything sound bigger.

W3T (Wet v3)The flagship. Smooth, three-dimensional, with adjustable pre-delay — it enhances what you play without covering it.
HallThe lush, open sound of a concert hall, with adjustable modulation depth for deep, moving tones.
PlateBright and diffuse, like a classic studio plate.
SpringThe distinctive twerp of a tube-driven spring — push the modulation for a vibrato-spring sound.
SustainA new algorithm built on W3T. Configure it as a sustainer or an infinite reverb.
EchoThe W3T reverb combined with stereo echo for ambient, rhythmic space.
DetunePitch-shifted shimmer movement under the reverb tail for a wide, modulated wash.
ShimmerOctave-shifted reverb that rises into ethereal, cathedral-like texture.
Under the hood: The Immerse Mk II's algorithms were designed by Brian Neunaber, whose reverbs are celebrated in studios and on stages worldwide by artists including John Mayer and Joe Satriani. This is the same engineering behind the Wet Reverb and the Illumine — the W3T algorithm at the heart of this pedal also powers the reverb block inside the Quilter Elevate.
8 Stereo reverbs
Stereo In & out
0ms Dry latency
Analog Dry path

Run it in full stereo for a huge, immersive wash, or plug into a single amp and Immerse sums to mono automatically with only output 1 connected. Powers from any standard 9V or 12V pedal supply, or a 100mA brick output. Heavy-duty build, small footprint, and a sound that earns its spot on your board — whether it's your only reverb or the secret weapon at the end of the chain.

How Immerse Compares

Immerse Reverberator Mk II — $269

The Immerse isn't built to be the everything-box stuffed with menus and presets. It's the best-sounding, simplest, lightest pure-reverb pedal you can put at the end of your chain — studio-grade Neunaber algorithms, a true analog dry path, real stereo, and zero learning curve. Here's how it stacks up against the reverbs you're cross-shopping.

The Ventris and blueSky pack in presets and MIDI — and cost $100–160 more. The Oceans 12 matches the price with more modes, but trades simplicity for menus. If you want a wall of options to manage, buy one of those. If you want eight world-class reverbs you can dial in by ear, an analog dry path that never touches your tone, and the lightest box on the board — Immerse is the one.

Digital Reverb......Not for me?

In the last 30 years I have tried reverb pedals from various builders and found that the sound and tone of them caused me to shut them off more than wanting to use them. Then I learned of Nuenaber reverb pedals. I hesitated to buy the Immerse MK II because of my history with digital reverb pedals. I'm so happy I bought this pedal though and experienced Nuenaber technology! Fantastic reverbs that enhance and don't get in the way of my playing. The Wet3 reverb setting is amazing! The spring reverb setting authentic! I can't say enough! Buy one! You won't regret it! Seriously! Just do it!

Immerse Mk II impressions

Hand down the best sounding small format reverb on the market and the “no learning curve” design and affordability make it a no brainer for anyone. The way you have voiced the texture of the reverb is just the best no matter what mix setting is used. I have two other big name brand reverb pedals in my set up and the Immerse Mk II the pedal that’s always “on”. From Surf to Interstellar this gets it done. Thanks for a very musical product.

Shimmers!!

I chose this pedal to replace the big sky on my board that just took up too much room. I tried TC electronics shimmer and was dissatisfied but with Immerse MK11 you get so many choices from shimmer to echo and other great tones in between and your able to manipulate the sound on the fly which is important to me playing live shows. I also have the neuron gain intelligence as an overdrive pedal and its fantastic! So far very happy with Neunaber❤🎸🎶

Astounding

I love this pedal more than any other pedal I've got,it's that good..The sound is amazing, Easy to get good sounds quickly..It's got the classic reverbs covered..and at high Depth and Mix it turns into an Ambient players dream..Plus it has cool xtra features like Shimmer, Chorus and Delay.. Least we not forget 100% wet at the turn of the Mix knob..I can't recommend this gem of a pedal enough..If you want quality, variety and ease of use..the Immerse Mk 2 has it in spades....

Beautiful sound, design, & build quality

The Immerse Mk II is a little gem. At first blush I like it better than I expected to; and that was a lot, since I was considering this pedal for quite a while. Excellent work. Thank you.

Reverb out of this world.

Its been 2 years now since i bought my first Neunaber pedal, the Immerse MK 1(still have it and never going to sell it). And was instantly hooked. Pretty soon after came the MK2, the Seraphim V2, the WetV2 and an expanse pedal. Soon i will buy the Echelon, Iconoclast & Neuron to complete my collection. But just as i thought i had seen it all, the ILLUMINE Showed up. I counted the time on the website and bought one immediatly the second it became available, haha! I did a quick runthrough through the presets and algorithms. And i can say, by doing that only, you get your moneys worth with these otherwordly algorithms. As soon as i pressed it on and startes playing, this incredibly detailed, lush, atmospheric sound gently rubbed my ears. I will post another review later after i messed around with the parameters a bit. That being said, you simply owe it to yourself to try this one out. Dont let the price tag scare you off, as soon as you plug this pedal in, you'll be blown away by its potential. Simply put: Out.Of.This.World.

The most expressive reverb I've ever used

Expressive and reverb aren't terms I've ever linked before, but the Immerse has introduced me to a new world! All the classic styles are there to be dialed in - but the way you can control effects like Sustain with hand-damping is a total revelation to me! Add the classy chorus-style Detune and dream-like Shimmer and you've got multiple effects in one pedal that take it to new levels beyond traditional reverb. I'm still exploring its possibilities, but I can already say the Immerse Mk. II is in a different league to anything I've tried before. Put simply - it's just gorgeous!
