The UVM is a compact amp-like sine wave tremolo, with a vintage modern spirit. It has Speed and Depth knobs to control the intensity and speed of the volume modulation. There is a super useful Boost control for perceived volume loss. There are also 2 toggle switches, one for Hard/Soft to give the Depth switch more intensity and the other for changing the Speed by Half/Double.
Product information
Tremolo pedals- volume modulators- can, on high depth settings or very fast speeds, play a trick on your ears. You hear an overall volume loss during the peaks and troughs so post volume modulation amplification is needed to make up for the loss. The UVM boost circuit is very clean and doesn't color your signal.
The UVM can also be used as a stand alone boost with the depth knob all the way down and the depth toggle set to Soft. It's a full range boost with no coloration of your tone. All the way counter clockwise is unity gain, the volume only goes up.
There is a useful LED that flashes with the tempo even when the pedal is off.
