Super cool gritty grungy fuzzy distortion / spring reverb with a TON of character. Has an fx loop where you can set it to ignore the fuzz circuit and put your own gain pedal in it. I bought it brand new from holyisland audio but the "swell" footswitch didnt work and it had a bit less gain when set to max. Otherwise everything else works perfectly and sounds awesome. He sent me a replacement so this one has hardly been touched.
