Neo Instruments Micro Vent 122 Rotary Speaker Simulator

Classic Leslie in a Stompbox

Neo Instruments packed their renowned Ventilator rotary speaker simulation technology into a compact guitar pedal form factor. But while they shrank its size, they super-sized its sound quality. The micro Vent 122 is packing crazy powerful DSP just like its bigger siblings, Ventilator II and mini Vent II. Neo Instruments even added a new circuit — analog blend — which allows for latency-free parallel processing of the wet and dry signals. Delivering killer sound in an attractive, roadworthy housing, Neo Instruments’ micro Vent ups the ante for rotary emulation effects pedals.

Deriving its algorithm from the acclaimed Ventilator II (very popular here), the micro Vent 122 simulates the classic Leslie 122.

Two speeds

The micro Vent has two adjustable speeds. Controllable via a pot, Speed 1 ranges continuously from slow to fast, while Speed 2 is selected via a 3-way switch offering the standard speeds — slow, fast, and stop. There are special switch modes that allow flexible switching: for instance, from slow to fast, fast to slow, stop to fast, slow to stop, and more. The creative combinations on tap are mind-bending. The Ramp parameter determines the acceleration and deceleration between the two speeds. Take it from us: you’ll never tire of hearing the rotors spooling up and down, re-creating the legendary sounds that made the originals so magnificent.

Switch modes

The micro Vent’s Bypass switch is more than just a bypass switch. In addition to switching the effect on and off, you can select between the two speeds. It is either momentary or latching depending on the mode, and you can also use it to only select speeds while leaving the effect on. This is very useful for creative performances when the micro Vent is used with a switching looper.

Analog blend circuit

Legendary guitarists such as David Gilmour and Stevie Ray Vaughan achieved their distinctive sounds by miking rotary speaker cabinets and guitar amps and blending them together. To nail the essence of this effect with only one amp, micro Vent features an analog blend circuit that allows latency-free mixing of the dry and wet signals for that classic rotary sound we all crave.
