You missed it!



This is the Starla – a clever and well-featured tap tremolo in a compact box. Analogue tremolo with digital control.

Dawner Prince in Croatia got our attention because they made another Binson pedal – the “Boonar” – and naturally we needed to try one. The result of that was that we had to have it. Boonar pedals are now in stock. From talking to them and looking at their gear we really like how these guys think and so we’re taking on some other interesting pedals that they do – as well as this pedal we’ve also taken on their excellent Viberator – a stereo Uni-vibe-type phase shifter

We’ll post more info and our own demo once we’ve had a proper play with it, but in the meantime here below is what Zoran at Dawner Prince has to say about it and a video demo. If you have any questions please get in touch.


Starla is a synthesis of two precisely combined electronics. It is a superb sound quality analog tremolo controlled by a versatile digital tap tempo microprocessor via optical technology – a light source and photocell.


On minimum settings, Starla can be used as a signal booster. Increasing the depth control, increases the tremolo effect in your signal; from light shimmering, through mild transparent-traditional, all the way to a deep swings and ‘machine gun-like’ sounds. Thanks to a huge depth range, this tremolo is able to chop up any signal sent in or out of it. It is very useful when put in front of high gain amps or pedals as it can cut the sound down to a dead silence.

There are 3 ways to set the speed of the tremolo effect: by using a speed knob, tap tempo footswitch or control voltage/remote tap switch via Sync port. Speed is affected by the position of the Multiplier (1/3/2) toggle switch. If the Multiplier switch is set at a higher rate, speed knobs sweep will change as well.

Starla utilizes eight different waveforms, including a random one. Combining every waveform with Duty trim potentiometer produces numerous wave shapes for you to explore. Duty trimmer pot modifies the duty cycle of all waveforms except Random.

We added volume control for two reasons: first to avoid a noticeable drop in volume when effect is engaged, which is a problem most tremolos have, and second to be able to use Starla as an excellent volume booster without adding any distortion to the signal when Depth control is on minimum setting.

Sync port
This port allows Starla to communicate with other devices. Depending on how the internal jumper is set up (remove the backplate to reach the jumper), Starla can send control signal to synchronize other devices to its’ LFO rate or it can accept control signal to be synchronized by other devices. It can also accept remote tap foot switch.

Tap tempo
Starla’s tap tempo microprocessor calculates tempo by taking the last two user taps so it plays in sync with your music. You can also choose different tap to tremolo rate ratios using 1/3/2 Multiplier switch: 1:1, 1:2 and 1:3. Once a tempo has been tapped in, Multiplier switch serves as an in-time speed control.

True bypass
Starla Tap Tempo Tremolo is equipped with microprocessor driven true bypass relay switching system. Holding down Status footswitch during the power up allows you to preset whether the effect powers up in effect-on or effect-bypass mode.

We are very proud of our Starla™ Tap Tempo Tremolo effect pedal and we believe it will inspire you to be even more creative in making music! Enjoy!
