Spring – The distinctive twerp of a tube-driven spring reverb. Now with adjustable modulation speed, it can achieve a vibrato-spring sound. Over the past few years his company has built a strong reputation for their multi-mode digital effects, in particular for their lush reverb and delay pedals, receiving especially high marks for their shimmer reverbs.

An absolute monster of a reverb. Will take you to places you've never played. I've played it for nearly 3 months and it has changed everything for me. Brian Neunaber of Neunaber Audio might be based in Orange, California, but the rigor he puts into his pedal designs betrays the mitteleuropean origins of his last name (for the unaware, Germans seem to have a special gene for engineering). The Immerse Mk II houses eight stellar stereo reverbs — W3T (new Wet version 3), Hall, Plate & Spring Reverb, Shimmer, Wet+Sustain, Wet+Echo, and Wet+Detune. Each effect has been painstakingly crafted: there are no fillers here. Delivering unrivaled sound quality and no-nonsense flexibility in a compact footprint, the Immerse Mk II can be used with instruments of all stripes. While other members of the Neunaber family give you one setting on board that be changed using either a computer or the optional EXP pedal the Immerse Reverberator has much more tweakability on the go. With 8 different reverb options including wet, hall, plate, spring, two types of shimmer, +echo and +detune you have a lot available here. Shimmer– Reminiscent of a synth pad that follows what your instrument plays, this effect combines the best qualities of our previous shimmers.As in the pedal’s previous incarnation, each mode can be tweaked through five knobs: Effect Selection, Mix, Depth, and two multi-function controls. In addition, external Kill Dry and Trails switches and stereo in/outs that can be used in mono or stereo contribute to make this stompbox also extremely flexible. The Immerse can do full wet which when used with something like the hall setting can be perfect for ambient soundscapes. There are a couple of switches on the top for trails, when engaged this will keep the trails of the reverb going when the pedal is turned off until they fade out. And a kill dry for if running it in a parallel effects loop. I don’t so I haven’t turned this one on. I have trails turned on but I very rarely turn the pedal off so I haven’t really used this feature. W3T (Wet version 3)— exclusive to the Mk II, our new flagship reverb is smoother and more three-dimensional sounding than ever before. Now with adjustable pre-delay, it enhances what you play without covering it.

Negatives: no presets, it’s on the pricey side especially when you consider that it doesn’t have presets and a lot of reverbs in this price range have them. An option for a favourites switch like strymon have would be nice even if it meant the pedal was wider or taller as it’s already very compact. This is quite a minor gripe, but hopefully something that might be remedied in a later version.This week Neunaber unveiled a new version of their flagship multi-mode stereo reverb, the Immerse MkII, which features new circuitry, and upgraded algorithms that were fully redesigned from the ground up “they are certainly the best I’ve created to date” – says Brian. Detune– Adds a detuned double of the dry signal with reverb, now with true blend control between detune and detuned reverb.
