• Dawner Prince Electronics Pulse review

    Rotating speaker cabinets has been an essential part of David Gilmour’s tone since the early 70s. There’s been many pedals over the years, trying to capture that elusive tone and some has indeed succeeded. The newest on the market is the Pulse from Dawner Prince Electronics. Here’s my review. 

    I’ve had the pleasure of playing through Leslie cabinets in the studio while recording and it’s quite the experience. Still, dragging a Leslie on tour is a real hassle, so enter the pedals. 

    I have no idea what it takes to create a pedal as far as the electronics go but what I do know is that a rotating speaker isn’t really an effect like a distortion or a delay. It’s more a physical phenomenon that occur when sound moves. Some rotary pedals sound like a chorus and are not very convincing. Others have manage to capture that physical 3 dimensional character. 

    The Pulse is, as the name implies, based on David Gilmour’s custom Doppola open speaker rotating cabinets that he used during the 1994 Division Bell tour. These had two 6 inch 100w speakers each and were based on the Gibson Maestro Rover that David used for recording Division Bell. Read more about the Doppolas here

    This strange looking satellite Maestro Rover sounded very different from a classic Leslie. While a Leslie has a rotating horn and a distinct tremolo-like modulation, the Doppolas and Rover had a much more airy, almost flange-like tone. David would blend in just a hint of that modulated character to his dry amps and pedals. Read more about the Maestro Rover here

    If you’re mostly used to hearing a Leslie or pedals like the Strymon Lex, you might need some time getting used to the Pulse. It sound very different but, spot on what it’s supposed to do. 

    The pedal is about the size of a MXR Flanger, with controls for controlling the fast and slow speeds individually, mic distance to the speakers, ramp up/down between slow and fast and a mix or effect volume. It can run in both stereo and mono and is powered on 9V adapter.

    It can be hard to notice the rotary modulation on David’s guitars on Division Bell and Pulse but’s definitely there. It’s not supposed to be an overly noticeable effect but rather something that adds character to his tones. The Endless River album is perhaps a better reference, where the original guitar tracks from 1993 are much more honest sounding compared to the fairly heavily produced Divison Bell. 

    The Pulse manages to capture that airy, almost 3D like tone. Even in mono, the pedal adds a huge complex texture to your tones, something between a Leslie and an Electric Mistress flanger. 

    The mix control allow you to blend in the right amount of the effect, whether you want just a hint of that slow rotary or a deep fast speed tremolo. It can handle high gain distortions and Big Muffs very well too. 

    I’m super impressed over the Pulse. It’s a bold pedal to make as it is so clearly modelled after a specific and rather obscure rotating speaker model. This is obviously not just another attempt at making a Leslie sounding pedal but a super accurate replication of a sound unique to David Gilmour.

    Hi Bjorn,
    Thanks a lot for this review. Which pedal would you say is best suited to replicate the Yamaha RA200 (Animals, The Wall tones): Boss RT20, Dawner Pulse, Ventilator?
    Thank you in advance for you advice.

    • Bjorn says:

      The Vent is closer to the Lex and that deep woody tremolo of the Leslie. The RT20 and Pulse are much closer to the Yamaha and Doppolas. As much as I love the RT20 and will still be using it for certain applications, I think the Pulse is a much more authentic recreation of the Doppolas and Maestro Rover in particular.

  2. Erwan says:

    Wonderful demo as always, I just ordered it!
    Do you think it’s possible to get a more vintage Gilmour tone like Dark Side with the Pulse? Thank you again Bjorn for your work

    • Bjorn says:

      Yes, although David used a Leslie back in the early days, he always used those in combination with his guitar amps so the result is much the same as how he did it with the Yamaha and Doppolas. It’s that slightly modulated character that’s added to the dry signal.

  3. Richard C Lynch says:

    It’s all about the details. Dawned Prince does get it and once again delivers. Great addition to the feel!

  4. Phil B says:

    Sounds awesome! Talked to a friend and he told me after seeing/hearing the Pulse he immediately put his Boss RT-20 on Ebay so there you go :D
    Wonder If David would use or at least try this, since he is already using the Boonar :P

  5. Michael Nagher says:

    Yet another great review. Thanks for all the work you do to keep us Gilmour fans up to date. Question is, is this pedal worth replacing my Boss RT20 ?

    • Bjorn says:

      They’re very similar in that they’re both much more chorusy and airy compared to a Lex or Vent, which has more of that dry, woody tremolo of a Leslie. As much as I like the RT20 and probably will continue to use it for certain applications, I must say that the Pulse blew my mind! Dead on David’s 90s tones.

  6. Ant Miller says:

    Excellent review again mate, thanks so much for this! I’m obsessed with the pulse tour tone. The rotary is a problem though and I have an RT20 which is hard to get the tone. I was about to push the button on the ventilator II until this review came along in the nick of time. I only want a rotary pedal for the subtle modulation for pulse tones. Would you say this is the best pedal to get please Bjorn?

  7. Bryan says:

    How would you say it compares to the Boss RT-20? Was about to buy the Boss and now I’m curious about this pedal.

    • Bjorn says:

      I like them both and have been using the Boss for years but this is no doubt a more authentic recreation of David’s 90s sounds, with the Doppoals and Maestro.

  8. Toftaky says:

    Like often I came to watch this review knowing I will probably not buy this pedal but just wanted to see and hear some Bjorn guitar impro, and like always I am never disappointed ! Thanks man ! ;)

    P.S. : even if I will not buy it, seems to be a really nice pedal though.

  9. Giovanni Grossetti says:

    Hi Bijorn,
    Thanks for the review and congratulation for the excellent work and service you do with your website.

    I have got the pedal last Friday. It’s amazing. The interesting thing is that I have used it on bass and works flawlessly. It also blends favorably with a Boss CE-2W and Effectrode fuzz.

    I am putting hope on their Boonar TUBE deluxe.
    Best regards
