Still in the honeymoon with this pedal, but I'm loving it. Never had a Klon circuit before, but so far it's everything the circuit is known for. Adds a lot of sparkle and bass, just a hair of grit (seems to make my amp more dynamic), and really stacks well. Right now I'm really enjoying putting a tonebender into it. Takes the shrill top end out of the TB (in this case a Throbak Stonebender) while still keeping that pedal's feel in tact. Awesome pedal! Wish it had graphics to distinguish itself from a large grey box, but it sounds terrific. And the price is hard to beat!
