TREMSTER - NATURAL ORGANIC TREMOLO EFFECT
Tremster's strength lies in the way the effect is modulated. In simple terms, this means that the waveform used to control the volume up and down (creating the tremolo effect) is quite special. Instead of a sine wave or a triangle wave, Tremster's waveform is smooth around the peaks, but otherwise relatively steep. It creates a very subtle effect that blends in with your playing – even at maximum depth. It's like it's breathing in a calm way instead of sounding like you're hyperventilating, so you can use MORE tremolo without losing anything, much like tube-tube tremolos on older amps.
Add a pulsing LED for visual indication of speed, true bypass and a mode switch for less/more pulse and you have a really nice and simple box that does what it's supposed to do, does it in a very musical way and without fuss. There are three dials, all analog, but the sound is what you pay for.
