Wagtail Trem (USB Rechargeable Optical Tremolo)


USB rechargeable ‘amp-style’ tremolo pedal for electric guitar



The Wagtail Trem is a Vactrol-based tremolo effects pedal for electric guitar. It recreates the legendary amp-style tremolo sound of the sixties that can be heard in songs like CCR’s ‘Born On The Bayou’ and ‘Gimme Shelter’ by The Rolling Stones to name two. Highest build quality and an innovative charging circuit make the Wagtail Trem the perfect choice for professional and semi-professional musicians as well as demanding hobby guitarists.


The pedal simply blew my mind. It behaves just like those old Super Reverb amps! The knobs react very sensitive. This vibrato is perfect for sound-surfing and it doesn’t overlay the output sound, instead it is perfectly placed underneath the sound. Absolute hit and recommendation!

No More Replacing Batteries!

The Wagtail Trem is rechargeable via USB, so you will never have to replace batteries again. Just plug it into your USB wall charger or your computer and in less than two hours it will be fully charged. The battery lasts more than 60 hours of playing time.
The charging circuit is designed to prolong the battery lifetime and ensure safe operation. It includes temperature monitoring, undervoltage and shortcircuit protection and CC-, CV- and Trickle-mode charging.


Vintage Sound – Noiseless

The analog circuit is a recreation of the famous optical tremolo that Fender built into their blackface and silverface amps in the ’60s. Furthermore the circuit has been optimized for lowest noise and distortion.


Never Run Out Of Battery!

Thanks to the new charge status indication you will never run out of battery: If the ON LED turns from green to red you will have at least five hours of remaining playing time.

Thanks to the included adaptor cable you can also charge the Wagtail Trem with a standard 9V DC power supply (Boss polarity).


Know Your Speed!

The ON LED also works as a speed indication.


No Mains Hum!
