Marshall Vibratrem VT1

 The VibraTrem. Authentic vibrato and tremolo effect pedal. Take a step back in time to the British amps of the early sixties thanks to the Vibratrem's authentic vintage effects. From groovy, trembling tremolos to psychedelic quasi-vibratos, the VT-1 is as authentically retro as you can get. And, its passive bypass ensures that your all-important guitar tone remains unaffected when you are not taking a vibratrem trip.
