The unmistakable sound of the Leslie! With the Viscount Vortex 315 Red Walnut, the traditional Italian manufacturer gives us a modern Leslie for all friends of the organ and the associated well-known effect of the Leslie. This product was developed and built with the help of Silvio Della Mattia, an esteemed and well-known connoisseur. Classic in function and technology, the Leslie works with rotating sound emitters and uses the Doppler effect to modulate the pitch. The Vortex 315 is completed with modern features such as presets, equalizer, MIDI/footswitch and an editor for Windows and MACOS/iOs.
