A gorgeously realistic faux-Leslie swirl in a compact package.

Digitally simulating a rotary speaker is ambitious. Because while the fundamentals of the rotary speaker effect couldn’t be much simpler (put speaker on stick, spin, and repeat) the wobbly, swirling, pitch-shifting delights that result are paradoxically complex and hard to replicate. Neo Instruments’ last rotary simulator, the Ventilator, blew our minds. It simulated the sonic intricacies of a Leslie 122 with startling realism. But it also enabled users to fine-tune details like balance between treble and bass horns and virtual microphone placement. The latest version of the Ventilator, the Mini Vent, has fewer features, but its Leslie simulation is no less stunning. And apart from a few hidden programming features that can be a bit tricky, the simpler, smaller version is as convenient and user friendly as can be.

Rotating Speaker Writ Small The original Ventilator was a smart piece of design, and in it’s own modest and simple way the German-built Mini Vent lives up to its big brother’s high design standards. The super sturdy square enclosure looks uncannily like that of a vintage ProCo Rat 2 and is about the same dimensions. Crack it open and you behold an immaculately tidy and cleverly arranged two-tiered printed circuit array.

Germany (May 12, 2014) -- Neo Instruments has introduced the Ventilator II, an effects device that emulates and faithfully reproduces the famed Leslie Model 122 rotary speaker sound. The company, based in Fulda, Germany, is manufacturing the Ventilator ll as a second-generation version of its successful Ventilator and a companion to two existing “mini VENTs” designed for both guitar and keyboard.

The original Ventilator is used by many touring artists including Chuck Leavell (Rolling Stones) and Craig Frost (Bob Seger). Guitar greats Steve Miller and John Mayer also use the Ventilator in their rigs.
