The name makes it sound like it will be extreme… the green color makes it seem like another TS clone or derivative. It isn’t really either. I find this to be a hugely versatile boost/od/distortion. The second position gives a full open sound while 1 and 3 give different levels of compression and slightly different behavior to the tone knob. I was able to match tones w my Tumnus. And stacked with another boost, it makes a nice harmonic distortion or fuzz. This knocked the Wampler Pantheon and Rats Bane off my board. Realty great pedal. 3 knobs means a simple guy like me can remember how to get the sounds he likes, as he cycles through different options.
