Smooth, deep and rich, bias tremolo is considered by many to be the pinnacle of amp trem sounds. Bias tremolo works by varying the voltage at the amplifier’s power valves, where it interacts with your playing to give the effect its unique character and magical dynamic qualities. 

Optical and VCA tremolo designs impose themselves on top of your playing, while bias tremolo has the capacity to respond to it. As power amp gain increases, loud notes and chords 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 notes die away. 

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


RevivalTREM contains a complete valve amp-style signal path with dedicated class-A preamp, a long-tailed pair phase inverter, and a push-pull output stage. Painstakingly modelled on our 1961 brown Deluxe, RevivalTREM benefits from Origin Effects’ Reactive Drive technology, and is the only pedal to bring you the sound of power valve bias tremolo. 


With the Shape switch in the Sine setting, RevivalTREM recreates the sinusoidal LFO waveform that makes vintage amp trem so smooth.

The Full Wave setting features an asymmetrical shape and higher duty cycle. This waveform has a characteristic ‘hump’, with a longer ‘on’ phase and a shorter ‘off’ phase—especially useful at slower speeds to add movement without obscuring your playing.


RevivalTREM goes far beyond the limited Speed settings of vintage amps. Use the Multi switch to shift the range of the Speed control or set rhythmic subdivisions. See the speed flash in real time on the Jewel Indicator.

Shift gears mid-set by connecting a momentary switch to the rear panel footswitch jack for easy tap tempo control.


RevivalTREM’s no-compromise Post-Drive EQ lets you tailor the pedal’s output to suit your amp, ensuring your clean AND overdrive tones always sound their best. 

RevivalTREM even includes a touring-friendly Power Amp Mode for compatibility with flat-response power amplifiers, so you can keep the show on the road whatever happens. 


Designed with the touring musician in mind, RevivalTREM features effects switcher integration for convenient remote control. 

Housed in a hand polished, brushed stainless steel enclosure and furnished with aluminium controls, Neutrik jack sockets and heavy-duty footswitch, the RevivalTREM is at home on the road as it is in the studio.
