From the manufacturer:
Have you ever wanted your tone to soar like a majestic eagle in a vast canyon? Perhaps you are a simpler mortal and just want your tone to echo like the cries of a sparrow in a small room... Now you can do both like a champ plus a whole lot more! Welcome to the Levitation™ reverberation machine! This Levitation device is a vintage-voiced reverb that aims to fit somewhere between dirty sixties chambers, classic spring and the big, ringing plate reverbs of days gone by. Four knobs and one switch control quite a bit more than you’d expect. Want a slap back small room sound? Set all of your controls to the minimum and use the mix to dial in the sound of room devoid of any thing but a guitar and amp. Want to revel in infinite spatial oscillations? Flip the toggle to Long, turn up the Atmosphere and Decay then tune out. Dial in a bright chiming slap back by turning the Tone all the way counterclockwise and reducing the Decay. Dime everything for a rattling, full-bandwidth assault. You are only limited by your imagination!
