For the countless gear pagers who say that the klon is only usable as clean boost, you obviously have not used it with a blackface fender. I used my klon as an overdrive for the first time tonight with my BF bassman cranked, and it just killed. i had the gain at about 3'oclock, the treble at about 2'oclock, and the output at about 10'oclock. I had gotten so used to using my klon as a clean boost and/or an always-on sweetener that i almost forgot how amazing this pedal sounds as an overdrive through a blackface fender. With the gain up, the klon just had so much more girth than all my other ODs...there really was no comparison...it made my strat sound HUUUGE. it even stacked surprisingly well with the gain up, providing that over-the-top sizzle for leads. People often complain about the klon's nasally mids or honkiness with the gain up, but the juicy mids are actually the perfect recipe for a mid-scooped BF fender...the klon really just makes your amp come alive especially in a band mix. ideally, it'd be great to have three klons on the board - one for OD, one for clean boost, and one to keep on at all times...if you haven't tried using a klon with a BF fender, i would highly recommend it!
