Deep, buttery, and seductive.

Designed to create vintage tube-amp tremolo, the Tremster uses a light-dependent resistor (LDR) to achieve its deep, buttery, and seductive sound. A flashing LED displays the current speed and permits a wide range from very slow to seizure-inducing head spinning. With the Mode knob in the normal position, the Tremster has an aggressive, sine-wave type effect. Depress the mode button and the effect is less aggressive with a square-wave quality. The volume knob delivers 3dB boost in maximum position. 9V operation. Handmade in Denmark, the Tremster includes a 2-year unconditional warranty.

    Comments about T-Rex Engineering Tremster Tremolo Pedal:

    I cant believe there are no customer reviews of this pedal- it's fantastic! I only wish everything else I've purchased over the last 20 years sounded so great! It's one of those magical pieces of gear that just sounds awesome no matter what! Good job Trex!
