The Origin Effects Revivaltrem is an strikingly interesting modulation and overdrive combo. Homing in on amp-like overdrive and tremolo effects housed in the same casing, the Revivaltrem is your vintage, analog-effect amplifier realized in pedal form. The Revivaltrem gives your playing that classic tremolo volume-shifting interaction your best vintage amp can. Intuitive speed and intensity controls drop players right in the action while Origin Effects' Post-Drive EQ controls give an element of compatibility not typically found in other pedals. The Revivaltrem brilliantly recreates an effect combo never to be forgotten.
