The Black Sun from Thermion might be the most detailed mono rotary speaker effect this side of lugging an actual Leslie to your next gig. The true-bypass circuit is all analog with controls over every parameter including Depth, Cycle, Subdivision, Horn cycle, Waveform, Speed, and Shift. The EQ is set with 2 bands – Horn for treble and Drum for bass. The Speed switch selects between 2 settings (Green/Red) controlling the amount of speed and shift of the effect. It can conjure the rotary speaker and phaser sounds of your favorite artists while giving you enough options to create your own sound entirely.
