In Zebra, what is SB3?

What is "SB3" in the Zebra effects list? To my uneducated ears it sounds like a Leslie simulator. Could someone explain what the SB3 is and what the Range, Freq, and Offset parameters do? Thanks.

They're called Sideband modules, the new beta Zebra2 manual discusses them:

The Sideband module is a stereo frequency shifter, the origins of which go back to the early days of radio. Related to ring modulation in which two signals are multiplied, resulting in two 'sidebands'. The Sideband module can also lend the signal a metallic character, as frequencies are shifted by a constant (e.g. 100Hz) instead of a factor (e.g. 2.00 times). While the 'beating' effect of mild oscillator detuning can become irritatingly fast when you play higher up the keyboard, frequency shifting keeps this effect constant.

You can download the manual and instructions for what each knob does in this thread:

A really good example usage of these modules is the preset HS Bell Bulder+ found in Zebra Factory -> 0 Two Point Five

Thanks! I looked in the new manual for SB3, not sideband.
