Opti-Vibe's great-granddaddy was introduced in the late 1960s as a rotary speaker emulator, but ended up being so totally unique that it was embraced by some of greatest players (Wooodstock '69, anyone? Or the Floyd circa '73?). Our design goes to great pains (and more math then you'd care for) to actually emulate the optical-sensor based design. In addition, we avoided the pitfalls in some recent reincarnations of this effect - some argue that modern versions were a bit harsh sounding. The result is that unmistakable and warm 'vibe' straight from the golden age. Also comes with a chorus/vibrato switch.


This is a very tweakable rotary speaker emulator: an effect that found a home with guitarists as well as organ players. Our design faithfully models the electro-mechanical Doppler effect and individually processes the drum and horn. The traditional Slow/Fast and Brake switches are also supplied. In addition, we have individually settable rotor acceleration for both the horn and the drum to get the perfect, interactive speed-up, slow-down effect. You can also specify the rotation rate for slow and fast modes, select among three drum rotor behaviors, and adjust the drum/horn balance as well as the mic separation for a mono or stereo rotation effect. Last but not least, RotaryBox includes three unique cabinet simulations as well as a DI mode if you are already using another cab.


A unique chorus/vibrato effect designed after the 'scanner' module found in certain famous mid 20th century organs, we expanded the design with stereo processing and a unique 'Chirp' feature that alters the tonality of the effect. Unlike standard chorus design, Scanner replicates a unique filter-based technology to achieve its effect. Comes with fully settable stereo spread and traditional C/V selector.
