Dawner Prince Electronics of Zmijavci, Croatia, released the Pulse revolving speaker emulator, the company announced on July 24, 2020¹. The pedal is an open cabinet rotary speaker emulator inspired by Pink Floyd's Doppola and Gibson's Maestro Rover RO-1²¹.

The Pulse uses a TRS stereo input, stereo outputs and an external input for an expression pedal or remote speed switch². The input accepts mono or TRS stereo signals, selectable via an internal jumper, but the rotary effect uses only the TIP IN (right) signal; in bypass, both TIP and RING inputs route to the corresponding outputs in stereo, and the pedal ships in mono mode². Stereo output comes from two virtual microphones placed on each side of the cabinet, and using only the OUT R mono output engages a single virtual microphone in front of the cabinet². The circuit is analog, per RockBoard's PedalPedia listing³.

Seven onboard controls cover slow speed (0.4 to 4 revolutions per second), fast speed (4 to 8 revolutions per second), distance (virtual microphone placement, furthest at minimum and closest at maximum), inertia (acceleration and deceleration time between slow and fast), mix (100 percent dry at minimum to 100 percent wet at maximum, with 50/50 at the 12 o'clock position), and separate output levels for OUT R and OUT L, with unity gain at 12 o'clock². A footswitch turns the effect on and off with a yellow status LED, and a second footswitch selects slow (yellow LED) or fast (blue LED) rotation². Switching is true bypass²¹.

Specifications from the maker's product page²; RockBoard lists the same 9V DC center-negative voltage and 70mA current³.

The Pulse carries a $339.95 USD price²¹. Premier Guitar reported at launch that the first run was available exclusively at the Dawner Prince web store, with worldwide dealers from mid-September¹. The maker's product page listed the pedal as sold out².
