Simple but fantastic!

Simple to use but fantastic audio quality. Plenty of options without being overwhelming. 4 different types of Tremolo; tap-tempo; hold Tap switch to double the speed; singlet/doublet/triplet setting; rudimentary rhythm setting; momentary "On" mode. Very good build quality - solid-shaft potentiometers, metal-collared knobs with set screws, solid enclosure. Battery or adapter powered.

Clever pedal

There is a bit of a learning curve to this pedal, but it's very useful once you get the hang of it. The "Chaos" mode and "Momentary" mode are a blast to putz around with. Aside from the usual hard-cutting tremolo/fuzz combo thing I do, use it for things along the lines of "How Soon Is Now," "Born To Run," "Evil" by Interpol, "You Should've Hung Out" by Rival Schools.

Shine on like TRM1

Awesome pedal, very warm and versatile tremolo with a tap-tempo function (wich is important to me). Great pedal. Great creative tool. One of the best tremolos i've ever played (and i tried a bunch). A must have !
