Great Leslie sound

Martin3471, 05.08.2014

Very impressed with the sound, in mono or stereo. I am using with a Hammond XB1, and the results sound very realistically like a Hammond + Leslie. The XB1 has a built-in Leslie simulator, but its effect is very weak in comparison. I had been using the XB1 with a MotionSound Pro3, which has a good sound itself, but the Neo Ventilator II is much closer to the Leslie sound. A real rotating speaker like the Pro3's horn has a richer spatial effect when you're next to it, but for mic'ed use, there's no advantage (and the Pro 3 only has a mono mic whereas the Ventilator simulates a stereo mic on the rotating horn.)

The Ventilator II sound is a combination of effects: rotating speaker effect, Leslie tone (frequency response of Leslie amp/cabinet) and Leslie amp overdrive. All of these are done well, and the combination is very convincing.

The Ventilator II provides a lot of control over the sound; the set of controls seems well thought out, and the ranges of adjustment are sensible. The second set of functions is a bit confusing at first - it means that the knob position may not always represent the actual setting. (E.g. if you moved to the second set of functions, changed the knob position for the second function, and then return to the main set of functions. The unit does the right thing, as it retains the setting you previously had for the main function of the knob, but now the knob is in a different position from that.) In practice the second set is unlikely to be changed regularly, so this slightly confusing behavior is unlikely to be a problem beyond the initial set up.

The unit has a sturdy steel case, and feels like it should last well. The "wall wart" power supply with plastic case could be a potential weak point. At least this comes with various pins to suit different countries.
