From Premier Guitar:
Stone Deaf earns our infinite respect for packing this much tremolo-sculpting power into a relatively compact enclosure. It can be a powerful and ultimately very streamlined way to craft complex and bizarre tremolo textures. The additional functionality that you get with the expression pedal and MIDI controls is considerable, and for players willing to leverage the whole of the Tremotron's potency, the pedal could become a powerful stage and studio fixture. That said, more casual players that love meandering explorations of a pedal’s capabilities will find treasure lurking at every turn in the Tremotron. And I won’t be surprised if a classic riff—or many—are born from the unique, unexpected modulations it can manufacture and the satisfying manner in which it rewards the curious.

So versatile, it inspired Andy to make TWO ProGuitar demo videos! That, in itself, is quite a testimonial.
