Critic Reviews

Neo Instruments Ventilator II & Mini Vent

soundonsound.com

Neo Instruments Ventilator II is a triumph in Leslie speaker emulation, offering convincing and authentic sound in a compact format. The Ventilator II excels with adjustable parameters for artists seeking precision, while the Mini Vent provides simplicity and portability. Both models deliver a rich, authentic rotary sound that enhances guitars, synths, and organs alike. While the Mini Vent’s preset values slightly deviate from a real Leslie, they still provide a satisfying experience. The need for a 12V power supply might inconvenience pedalboard users, but the overall performance makes it a worthwhile adjustment.

Neo Ventilator II review | MusicRadar

musicradar.com

The Neo Instruments Ventilator II offers a stunningly realistic emulation of the iconic Leslie 122 rotary speaker, with a user-friendly footswitch setup and detailed control options. Its sonic fidelity and multi-functionality make it a top choice for serious musicians seeking authentic rotary sounds. However, its high price tag makes it one of the more expensive options on the market. If you're after a smaller and more affordable alternative, the Neo Vent could be a better fit, sacrificing some controls for a lower cost.
