Farfisa Sferasound

Farfisa Sferasound rotary speaker effect pedal for sale.

Not the first effect designed to simulate a Leslie that uses an interesting design to get there – this uses an eight stage FET-based phaser (see the internal shots – it’s wild) and the obvious parallel in terms of idiosyncratic approach is the Schaller Rotor Sound with it’s 18 inductors. Information about them is relatively sparse but we’ve included detailed internal shots for those who are curious.

‘Idiosyncratic’ is also – perhaps unsurprisingly – a good description of the sound and other aspects of the design/controls. See below for a couple of youtube videos that give an idea of what it can do. You can get some passable rotary speaker effects in some cases, as well as ‘swirly’ vibrato and tremolo sounds, but things get interesting at more extreme settings. The controls on the bottom are obviously designed as set and forget – not ideal for those of us who like to fiddle with such things, and note that due to their design and age they may be little noisy as you adjust them.

Very rare in any condition; this one is now serviced and working as it should. Did you know they made a stereo rack version as well? That’s a story for another time though…
