The Neo Ventilator 2 is the latest in Neo’s highly regarded Leslie rotary speaker simulations. Leslie rotary speakers create one of the most sought after effects for keyboard and guitar players but the actual things are very expensive, very large, and very heavy; this pedal is neither of those things but it does give you an amazing simulation of the Leslie Rotary 122 Speaker in pedal form.

This pedal gives you complete control over the simulation so you can modify it to your preference with speed, acceleration and balance control allowing you to set up not only the speed of the rotors but also the acceleration and deceleration of the low and high rotors while the Balance control lets you control the mix of high and low rotors. The drive and distance controls allow you to control the simulation of the tube overdrive that is commonly found used with a Hammond.

Here’s what Neo Instruments say about the Ventilator 2 pedal

VENTILATOR simulates a 122 model rotary cabinet, mic’ed up with a stereo pair on top for the treble rotor and a single mono mic below for the drum holding the woofer. The Distance knob lets you move the virtual microphones closer in for lots of amplitude modulation with an intense stereo effect and further out to conjure more diffuse sounds with gentle modulation.

Individually Adjustable Rotors

The Speed knob adjusts the two rotors’ velocities, and the Acceleration knob determines acceleration and deceleration time. As on the original, the bass and treble rotors run out of sync at slightly different speeds. Acceleration and deceleration times also differ, with the bass rotor taking much longer to speed up and slow down. The Balance knob adjusts the relative levels of the two rotary speakers.

Tube Simulation

The Drive section is another awesome sound-sculpting tool in VENTILATOR’s kit. Don’t expect the buzz-saw rasp of a transistor-powered fuzz because it delivers all the warmth of bona fide tube-flavoured overdrive. The Drive knob dials in everything from a touch of grit to a real rock roar, all of which can be controlled extremely dynamically via an organ’s volume pedal.

Versatile Input & Outputs

VENTILATOR comes with a mono input and a stereo output. The Lo / Hi switch matches input gain to the signal source. You can insert VENTILATOR between your instrument and an amp or mixing console as well as into an FX loop.

Remote Control

VENTILATOR is a stompbox by design, but you can set it on an organ or keyboard for easier access to the knobs. Switching speeds is simple enough, either directly via the Slow / Fast stomp-switch on the device or remotely via a half-moon or external footswitch. If you are controlling the device remotely, you can also use a kill switch to stop the rotors. One LED each indicates the respective rotor’s current speed.

Speaker Simulation

An elaborate filter circuit emulates the frequency response of a tube-driven cabinet with exacting precision. When using a guitar amp, simply set the switch to GIT to defeat the speaker simulation and obtain practically linear frequency response.

True Bypass

VENTILATOR comes with a true bypass designed especially for use with guitars. This relay circuit patches the input signal through to the two outputs with no loss of tone or level.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Rotary

Rotary pedals recreate the swirling, moving sound of a rotating speaker cabinet, adding rich modulation and a sense of motion to guitar tones. They typically simulate the changing pitch and volume caused by spinning speakers, producing anything from subtle shimmer to deep, pulsating swirl. Rotary effects are often used for clean and lightly driven sounds to add depth, movement, and a classic, organ-inspired character.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
