TRM1

OPTO TREMOLO

Noiseless analog tremolo

The tremolo sound of a vintage amp

TRM1 gives you both the warmth and square wave attack of old tube amplifiers and the jagged triangle waves of modern rock, but without any of the crackling noise or noticeable drops in volume often associated with vintage gear.

With TRM1, you can easily dial in your desired sound, and it is the very first time we offer this intuitive design and no-nonsense layout outside our Custom Shop.

The Speed control naturally sets the speed of the tremolo effect, while the Curve switch toggles between square or triangle waveforms. The Depth control sets the intensity of the tremolo, and if you turn it fully clockwise, the original signal is cut off completely.

When switched OFF (bypassed), TRM1 acts as a unity gain line driver, capable of driving even very long cables without tonal loss or unwanted coloration.

“The Caveman Audio Tremolo is simply the best Tremolo I ever played”

“I have always liked the sound of the tremolo you find in old vintage amps – but not the noise they added. TRM1 is my take on capturing the sound of this unique effect in a small box – without the noise issues.”
