Critic Reviews

Neo Instruments Ventilator

soundonsound.com

Neo Instruments' Ventilator is a standout Leslie speaker simulator, praised for its authentic vintage tone and robust build. Ideal for both guitarists and organists, it closely mimics the classic Leslie 122 sound with impressive overdrive and warmth. While lacking a built-in 'stop' function and requiring an external switch, its performance outweighs these minor drawbacks. At a higher price point, the Ventilator justifies its cost by delivering unparalleled realism and convenience in live settings, making it a must-have for those seeking the quintessential Leslie experience without the bulk.

Replaced my 147 with the Vent

This will be a very short review of the Neo Ventilator.

For live use, I replaced my 147 Leslie with the Ventilator and have never looked back. Done, end of review! Now, you go get one.

Okay, one inherent feature I really do like is that the unit produces the 'swishing/swirling' sound a real Leslie makes. Even when there is no signal passing thru the Vent, the Vent sounds like a mic'ed cabinet. Without looking at the fast/slow LED meter, you can easily hear if the Vent is ready in slow or fast position before you play a chord.

Though, here is my wish list for improvements: -- need a rack-mount version -- needs separate L/R outputs for both Horn and Rotor. Hmmm, why separate? Because when using a real Leslie, I often like to put verb/ddl only on the horn and not the rotor. Also, I often like to pan the horn a left and the rotor a right...this creates a very wide stereo effect...with different speeds of motion going on in each speaker.....try it sometimes...you'll like it. -- needs separate acceleration/deceleration speeds for horn and rotor. -- remote fast/slow footswitch needs to have led-light that shows if unit is in Fast or Slow position.

I've been thinking about trying one of these or the destination rotation... haven't had a leslie in ages and I can't remember the last time my tube rotosphere was functioning.Probably since before I bought, modified and sold that leslie.
