wow. what an insanely great pedal..... first off, i am not a big "pedal guy". the only effects i really ever run are reverb, trem, and overdrive for leads. i've got a handful of amps. some have reverb, some have trem. the only one i have that has both is a vox pathfinder 15 i use at home mainly for songwriting. this thing makes my cheap amps sound GREAT and my expensive amps sound GODLY. the spring 60s spring reverb is the main verb i use with it and it sounds great. very lush and "drippy". the other two sound awesome. i'm surprised how much fun i've had messing with the 80s reverb. really can get some creative juices flowing, playing with over the top sounds i would usually never get to try. the trem options are incredible for one pedal. it nails my favorite trem vibes like slim harpo and magic sam. can get all the classic fogerty/ccr and even gets the johnny marr how soon is now vibe. it's an expensive pedal, but gives you so many options. worth every penny. definitely the best pedal i've purchased in a long time. maybe ever.
