The T-Rex Tremster is a humble, yet fantastic sounding tremolo pedal that imitates the lush tones of a vintage tube amp’s tremolo.

The tremolo has been one of the oldest effects for guitars dating back to the 1950s, and was first used in surf music. Combining simplicity with effectiveness, the Tremster features three simple controls to sound great on any setting. The Mode knob gives the Tremster a more aggressive and harsher effect when engaged. The vintage-inspired tones sound very natural when the pedal is engaged and will bring out the best in your tone.

Tremolo Made Simple
With only three controls for the Tremster including Depth, Speed, and Volume, easily craft your dream tremolo tone with precision. The depth controls the depth of the volume and oscillation while the speed controls the oscillation speed of the effect. The volume control sets the overall volume of the wet input but when the volume control is turned all the way up, there is 15dB input signal boost. The LED will flash in-time with the speed of the tremolo effect.

Aggressive Mode Switch
Engage the mode switch to boost your overall volume level and add some extra grit to the Tremster's tone. The switch allows you to switch between the original tremolo effect and vibrato effect. The tremolo effect works like a repeatedly radical change in volume. The vibrato effect has a subtler volume change.

Vintage Tones
The Tremster gives off those authentic warm and thick tremolo tones from the '50s. The rich and lavish tones add plenty of color to your sound while keeping your natural guitar tone transparent.
