Dawner Prince Electronics has unveiled Pulse, a pedal that aims to accurately portray the experience of playing through revolving cabinets such as Pink Floyd’s legendary Doppola, and the Gibson Maestro Rover RO-1.

Pulse operates in two speed modes: fast or slow. Notably, toggling between these two doesn’t happen in clear-cut, A/B fashion. The effect ‘accelerates’ or ‘decelerates’ depending on how the Inertia control is set, lending to the overall experience of playing through a real revolving cabinet.

Both modes also feature their own speed control knobs, with slow’s ranging from 0.4 to four revolutions per second, and fast’s going from four to eight revolutions per second.

The Distance knob, which acts as a virtual microphone placement control, adds further realism to the effect by mimicking either close or room mic’ing. Other notable features on the Pulse include a mix knob, an expression input, and stereo outputs.

According to the brand, the development of Pulse was rather arduous, and involved the use of some heavy mathematics, all in the spirit of producing a believable emulation.

“We spent countless hours on R&D, measuring every detail on a real physical model and using advanced math to emulate its complex sound image along with all the physics and mechanics behind it,” the brand wrote. “And it’s all in there – a realistic three-dimensional sound that swirls as the speaker accelerates, exact spatial modulation and the feel of the air moving with every spin.”

Pulse is available now for $339.95.
