Union Tube & Transistor’s first foray into digital is a reverb with two engines. The knob on the right blends in what you might think of as a large reverb that gets into almost infinite territory as you max out. The knob on the left is a reverse modulated reverb. The centre knob is a pitch for the reverse modulated which at noon does not change the sound but goes down (to the left) or up (to the right).
