Its
that awesome! i love it! I didnt like any of the video demos of it, but i was really interested in a ring mod. Its a very different kind of ringmod than the moog(which is the only other ringmod i can compare it with), its alot "dirtier"? Its more unpredictable and it stacks way better with other effects(i think). I think it really shines when you use it with distortion pedals.
Im not a fan at all of the regular trem function on it, because its way to noisy for post rock or other semi clean playing, and the range is a bit isnt all that great. with that said, the tremolo function is awesome if you dont think of it as a tremolo and try to tune it to the base note of the riff your playing. Then it adds alot of character to chords etc. I hope that helps, if i were you id go for it.
It has a bit of a learning curve though, i didnt like it very much for the first two months, but then one day it just clicked, and now its my favourite pedal!
