Dawner Prince Eclipsa

The Dawner Prince Eclipsa, sold as the Eclipsa Triple Rotary, is a rotary cabinet emulator and preamp pedal that recreates the Yamaha RA-200 rotary speaker cabinet, a cabinet known from the late 1970s, and pairs it with an Alembic F-2B-style preamp built with FET technology¹². Where most rotary pedals chase the Leslie sound, Dawner Prince went after a different cabinet altogether: Guitar.com's reviewer called it "a tribute to the near-forgotten Yamaha RA-200"². Premier Guitar describes it as a rotary cabinet emulator inspired by the famous Yamaha RA-200 system, recreated through detailed DSP modeling that captures both the tonal response and the complex movement of the original³.

It is a digital pedal with a lot of performance control: 127 onboard presets plus a Live Mode, full MIDI, stereo outputs derived from three virtual microphones, and an expression input for continuous speed control¹. It lists at $589.95 USD¹, and as of late October 2026 the maker's product page shows it as Sold Out¹.

What it models: the Yamaha RA-200 and Alembic F-2B

Dawner Prince describes the rotary section as "a full rotary cabinet recreation of the iconic Yamaha RA-200"¹. Guitar.com's Richard Purvis frames it the same way, noting the pedal recreates the sound of the Yamaha cabs used at the end of the 1970s as well as the Alembic F-2B valve preamp². The preamp side is an Alembic F-2B-style circuit implemented with FET technology rather than tubes, which is what lets it fit in a pedal and run on 9V¹.

The RA-200 basis matters for players comparing rotary pedals. Guitar.com's reviewer found the Eclipsa delivers "rich rotary tones but with a distinctly non-Leslie voice"², which is the practical difference between this and Leslie-style emulators like the Boss RT-20 Rotary Ensemble, the Electro-Harmonix Lester G Deluxe or the Strymon Lex. It belongs to the wider family of speaker simulation pedals, but its job is the moving speaker, not a static cab.

The controls and footswitches

The Eclipsa carries two soft-touch footswitches and a set of knobs Dawner Prince lays out around the preamp and the virtual cabinet².

The Inertia control is the ramp-time control: it sets how quickly the virtual rotor accelerates and decelerates between fast and slow, the behavior a real rotary cabinet exhibits when you change speeds¹. The Distance control works with the three virtual microphones, changing where they sit relative to the cabinet and therefore how wide and close the effect feels¹.

Guitar.com's reviewer found the controls "cleverly laid-out" and praised the preamp as "easily set always-on", meaning the buffered Preamp-On mode lets the F-2B-style front end stay in your chain permanently while the rotary effect comes and goes²¹.

MIDI, presets and expression control

The Eclipsa has full MIDI implementation: Control Change messages adjust parameters, Program Change recalls presets, and the MIDI channel assignment is configurable¹. With 127 onboard presets plus Live Mode, complete performance setups can be stored and recalled¹. The rear panel carries MIDI In and MIDI Thru alongside the audio jacks⁴.

The EXT IN jack takes an expression pedal for continuous rotary speed control¹, so instead of toggling between fast and slow you can sweep the speed smoothly with your foot, the way a volume pedal or expression pedal works elsewhere on a board.

Stereo outputs and bypass

Outputs are mono and stereo: Left/Mono and Right, both derived from the three virtual microphone signals¹. Premier Guitar likewise describes stereo outputs via three virtual microphones³. Run in mono the pedal sums to a single output; in stereo the virtual mic placement gives the rotary movement its width.

For bypass, holding the footswitch toggles between True Bypass and buffered Preamp-On modes¹. Premier Guitar also notes a magnetic, contactless true bypass switching system³.

How it differs from the Dawner Prince Pulse

The Eclipsa is the successor to the Dawner Prince Pulse, but it models a different cabinet. The Pulse was based on the Maestro Rover RO-1, an open cabinet revolving speaker inspired by Pink Floyd's Doppola and the Maestro Rover RO-1⁴⁵. The Eclipsa instead emulates the Yamaha RA-200 and adds the F-2B-style preamp, which the Pulse did not have⁴¹.

The feature set also grew: the Pulse has stereo input and stereo outputs with an external input for an expression pedal or remote speed switch⁵, while the Eclipsa adds MIDI, 127 presets and the three-virtual-microphone output architecture¹. On Guitar Pedal X, Stefan Karlsson wrote that "there's no question the new unit is more capable and refined" than the Pulse⁴.

Build, maker and availability

The Eclipsa is made in Croatia, which Guitar.com's reviewer found was "to a reliably sky-high standard of workmanship"². It sits in a custom CNC-machined, anodized aluminum enclosure that Dawner Prince says provides long-term durability and mechanical stability¹. The design comes from Zoran at Dawner Prince, credited by Guitar Pedal X as "another fantastic creation"⁴.

Premier Guitar reported that the first batch was available exclusively through the Dawner Prince Electronics web store, with broader dealer availability worldwide from late May 2026³. As of late October 2026 the maker's page lists the pedal as Sold Out¹.

What reviewers said

Guitar.com's Richard Purvis reviewed it at £499/$589.85 and summed it up as rich rotary tones with a distinctly non-Leslie voice, cleverly laid-out controls, an easily set always-on preamp and a beautifully solid build overall². On practical playing, he found the slow mode sounds better on the bridge pickup with some overdrive, while the fast mode sounds better on the neck pickup for what he called sweet and shimmery wibblage².
