"The SBF has 5 modes appropriately named “Flanger I”, “Flanger II”, “Flanger III”, and a Chorus mode that is part-for-part the closest thing you can get to the famous Juno choruses.

It has cool front and back panel inputs for both channels, it has phase invert for both channels (to get some nice swirly action going) and a CV in to control the frequency of the pitch externally (great for Eurorack modular setups!). This external control is another of those unique and creative features that make this box rock.

Flanger I is summed mono and sounds great. Flanger II is the stereo flange and sounds better, and Flanger III is a cross-feed flanger that sounds even better. You can run one sound in/out in stereo, or run two separate in's to get two different output signals. It's like having two flangers or two choruses in one box."
