The RevivalTREM is the first ever pedal to faithfully recreate power tube bias tremolo, the sought-after effect found in a handful of classic amps from the late ‘50s and early ‘60s.

More than just a tremolo pedal, the RevivalTREM also delivers a deliciously chewy and rich Brown Fender-style overdrive tone that interact with the bias tremolo effect just like the real thing.

True power tube bias tremolo, in a pedal!

Based on the RevivalDRIVE platform, the RevivalTREM houses a complete valve amp-style signal path recreated in all-analogue electronics.

This allows it to recreate the uniquely musical and dynamically responsive bias tremolo effect at circuit level, while also offering a broad palette of stunning clean and overdriven amp tones voiced after the Brown Fender Deluxe.

A range of modern features, including switchable wave shapes, tap tempo, rhythmic subdivisions and effects switcher integration, bring modern convenience to the RevivalTREM’s authentic vintage tones.

Dynamically responsive tremolo

Smooth, deep and rich, bias tremolo is considered by many to be the pinnacle of built-in amp trem. In contrast to optical and VCA-based tremolo designs, which attenuate the signal itself, bias tremolo works by varying the bias voltage fed to the amp’s power tubes, giving the effect its unique character and almost magical dynamic qualities.

While other tremolos impose themselves on top of your playing, bias tremolo has the capacity to respond to it. As power amp gain increases, loud notes and chords are able to rise above the effects of bias modulation. Digging in harder allows you to “play over” the tremolo effect, before letting it fade back in as the note dies away or you soften your pick attack.

The RevivalTREM’s amp-like circuitry reproduces this effect exactly, right down to the complex interaction between gain, bias voltage, playing dynamics and harmonic content.

Authentic Deluxe tones, from clean to mean

Voiced after our treasured 1962 Brown Deluxe, the RevivalTREM serves up a range of rich and complex valve amp tones with stunning authenticity.

From gritty cleans through throaty and articulate break-up to growling Tweed-style distortion, the RevivalTREM’s repertoire of elusive Brown Fender tones is at your disposal, with or without the independently switchable bias tremolo effect.

Meanwhile, the powerful Post-Drive EQ section, as seen on the RevivalDRIVE Compact, tailors the output of the pedal to suit the voicing of the amp you’re plugging into, as well as flat-response power amps, mixers and recording interfaces.

Vintage tremolo meets modern features

As well as a wider range of Speed and Intensity settings, we’ve provided two different LFO wave shapes – a smooth, Deluxe-style sine wave and a less symmetrical, Magnatone-style rectified sine wave.

Attaching an external footswitch enables tap tempo and remote tremolo on/off switching, while the same footswitch input allows direct integration with effects switching systems like the Boss ES series or TheGigRig G2. The RevivalTREM’s speed multiplier switch offers quarter-note, eighth-note and triplet tempo subdivisions while also shifting the range of the pedal’s Speed knob.

With high-quality components throughout, the RevivalTREM is designed and built for professional performance and rock-solid reliability.

Please note: the RevivalTREM is powered by a mains adaptor only (not included). We’ve dispensed with the usual 9V battery option, both to save space and to allow us to adopt a high-current approach, yielding lower noise levels and superior tone.
