Croation pedal maker Dawner Prince Electronics have just released its new Pulse, a revolving speaker emulator. Dawner has aimed to put a Leslie speaker into a pedal – that’s somewhat lighter and more portable than the original! But a peek under the hood reveals: this isn’t actually a recreation of a Leslie cabinet at all!

Maestro Rover RO-1

The Dawner Prince Electronics Pulse pedal is all about those classic swirling, Leslie speaker-type tones we associate with Jimi Hendrix and David Gilmour, just in a manageable pedal format rather than a massive, incredibly heavy speaker cabinet. But this new Pulse pedal is actually not a Leslie speaker recreation at all. While everyone around the world still knows about the good old Leslie speaker, Gibson’s 1972 Maestro Rover R0-1 often gets left out of the picture. While the Leslie’s rotating speaker was housed in a sturdy wooden cabinet, the Rover looked almost like a UFO. It had some great features that were superior to Leslie’s. And it was perfectly tailored for guitarists. None other than David Gilmour used the Maestro Rover on 1994’s The Division Bell. He even took three specially made versions  with 100 Watts on tour, so-called Doppolas. You can find more information on

Dawner Prince says it took months of R&D to pack the hardware with real speakers as well as the electronics of the Doppola and Maestro Rover RO-1 into an effects unit. Emulating a rotating speaker with an open cabinet requires complex math, apparently. The Pulse Revolving Speaker Emulator, or Pulse for short, is intended to reproduce the complex sound image as a realistic three-dimensional sound and convey a feeling of actually moving air. Not an easy task. Since the device is clearly inspired by Pink Floyd’s legendary rotary speaker Doppola and Gibson’s Maestro Rover RO-1, and seeing as David Gilour is on Dawner Prince’s artist roster,  you’d be forgoven for thinking that Mr Gilmour initiated this project.

The Pulse includes a stereo output and an independent mix control that mixes the raw dry and the effects signal from the preamp. An expression pedal input lets you control the speed continuously. The rest of the controls are almost all self-explanatory: Slow Speed, Fast Speed, Distance and Mix. The ominously titled Inertia sets the amount of time it takes to switch from slow through to fast setting. The circuit is true bypass and the pedal is powered with a standard 9V DC input.

You can check it out in the demo videos below or follow the link to the company’s website for the full specification. It certainly sounds great and if you are chasing that Pink Floyd tone it could be for you.

RRP – USD 339.95
