Dawner Prince Electronics Unveils the Pulse

Croatian pedal maker Dawner Prince Electronics announced the Pulse, a revolving speaker emulator pedal aimed at the classic swirling, Leslie speaker-type tones players associate with Jimi Hendrix and David Gilmour¹. The company said the pedal was intended to reproduce the complex sound image of a real rotating speaker as a realistic three-dimensional sound and to convey a feeling of actually moving air¹.

Dawner Prince said it took months of research and development to pack the hardware with real speakers as well as the electronics, and that the design was inspired by Pink Floyd's legendary rotary speaker Doppola and Gibson's Maestro Rover RO-1¹.

The Pulse's launch features included:

• Stereo output, with an independent mix control that blends the raw dry signal with the effects signal¹
• An expression pedal input for continuous control of the rotation speed¹
• An Inertia control that sets how long the pedal takes to ramp from its slow setting through to fast¹
• True bypass switching¹
• Power from a standard 9V DC input¹

The maker later specified that the Pulse accepts 9V DC only, and warned that using more than 9V will damage the unit². It also handles input signals up to 2.5V, covering line levels². Almost any expression pedal works with it, with the Roland EV-5 suggested, and it accepts any SPDT (ON/ON) remote switch wired tip to the center lug, ring to the outer lug and sleeve to the second outer lug².

Units with a serial number higher than 00306-20 carry an updated design with an internal jumper allowing selectable TRS stereo input; the jumper sits on the lower left of the circuit board, with the upper two pins marked STEREO IN for TRS stereo input and the lower two marked MONO IN for mono input². Stereo signals require a stereo to mono Y cable adapter².

The Pulse carried a launch price of USD 339.95 RRP¹.

Guitar World later reviewed the Pulse, listing it as a revolving speaker emulator from Dawner Prince³.
