Rotary Speaker Effects Pedal

It’s in that moment when you start playing. You hear the speaker start to rotate and you sense the moving air. With a little growl it becomes magic from that first moment. This is what rotary speaker is about and with VENTILATOR II, you enter a sonic world of absolute perfection - handy, light and absolutely reliable. The best rotary speaker sound you could wish for, now it’s yours!

Analog tradition in digital form
For purists, only the original has been considered, because the forefather of all rotary speakers is the measure of all things. With VENTILATOR II you now have the very best alternative to the real thing, emulating every nuance of the originals in the most minute detail. All the character and the stellar sound of the real thing in a handy format.

It's all about sound
You feel every nuance of your sound as VENTILATOR II offers enormous sonic depth emulating the sound of a Leslie 122 Rotary Speaker – picked up with 3 mics. Its 3D sound lets you immerse yourself in the loudspeaker experience, as you perceive every rotation, with a sense of spatial location and moving air just like having a Leslie in the room – no matter if you use it with organ or your guitar. Where other effects only pan the signal between left and right, VENTILATOR II ‘s exact emulation of mechanical movement provides a unique psychoacoustic experience. That's why VENTILATOR II not only sounds great in stereo, but also in mono.

Uncompromising in every aspect
To emulate the original, capturing its character with all its strengths and unique sound-forming "weaknesses" in detail, no compromise was made in the comprehensive design of the analog section. VENTILATOR II provides extensive headroom with unadulterated dynamics - of course, with the lowest background noise. The high-performance 32 Bit Sharc DSP focuses all its resources on just a single effect, ensuring unparalleled digital perfection with low latency.

Control on every detail
VENTILATOR II offers a wide range of adjustment options for reproducing the behaviour of the original down to the last detail. Whether on stage or in a recording studio, with the controls and footswitches, you can dial in your favorite sound in no time. In addition to rotary speed, you have easy access to many other parameters such as microphone distance, acceleration and deceleration, drive, and more.
