I borrowed a Klon and then ordered one 15 weeks ago. It came today. I played it for 4 hours, using 4 guitars, and in many stacking and solo settings. It's even better than I expected/remembered: - Buffer: Using a mini bypass looper, I brought the Klon in and out of the circuit while turned OFF, just to hear the buffer. I've seriously checked out (bought/returned/sold) about 8 boosts and/or buffers lately, and had bought the looper because I expected this buffer to sound bad. WRONG! This is the least noticeable buffer I know of. Note: I always have my Eventide Time Factor buffer in line (at the end), and I love it's full, warm sound. When I add a second buffer, it usually sounds bad (hi-fi, articifical, crispy, stinky). OK, the Klon buffer sounds a HAIR more clear and a HAIR less in the mids then when taken out entirely. But it is very subtle, more subtle than others which claim to be great and sound way too bright. I decided to use the looper anyway because I record a lot and I figured I'll keep it pure. But in a live setting, that mini-looper will be the first to go if I need room to squeeze in another pedal on the board. - Boost: Many people love the Klon as a boost. First I tried it totally clean, with the settings "flat" as recommended (gain off, treble at noon, level at 10:00). It was quite simply THE SINGLE MOST TRANSPARENT boost I have ever heard. NO coloration. This was a big surprise. I couldn't tell that it was on. Brining the level up made it bigger and louder, but never crispy or boomy or humpy. Great! - OD into clean amp: This is NOT recommended by the maker. As others have noted, the gain adds a lot of midrange (and the pedal doesn't offer much gain on its own). But I did find that I could get a nice dirty-clean rhythm sound; not as open as my red snapper for this, but it'll do in a pinch. - OD into dirty amp: well, my amp is always clean (Bruno Cowtipper with volume at 9:00), BUT my whole approach is to set one of many Menatone pedals to the edge of breakup (clean to decent crunch and sing based on picking dynamics, meaning gain at 12-1:00) and with output set noon which hits the amp HARD, so the input stage is working. I use the output on the menatone as my volume control, but I like it at noon when I can get away with it. SO, the Klon sounds amazing like this. Doing what it's meant to do. With gain at 10:00 and treble at 2:00, I guess the mids are there, but it doesn't have that mid hump sound. In fact it is much more open sounding than either my burst Eternity or Zendrive, less mid hump and less compression. -Stacked with Eternity or Zendrive into either Howie, KOTB, TBIAC etc: Fantastic. Really. I got into long sustain, harmonics, etc. in a way that isn't harsh, isn't boomy, and still feels TACTILE! Any three pedals stacked will RAWK, but the detail, control, openness and musicality here were something special. Keep in mind that the Klon has gain at 10:00, the Eternty or Zen after it has gain at 9-10:00, and the Howie or other menatone has gain at 1:00. This is an amazing sound and experience. Guitars: I liked it equally with all my guitars when used as above. Collings I-35 and 290, strat, tele. I have others but these were all I used. Again this was a surprise. I thought I wouldn't like it with humbuckers. One last thing, I waited a long time and paid big bucks because this pedal worked with my gear to do the best pushed strat neck pickup thing (SRV, Mayer trio)that I've encountered. More than any TS variant. I was willing to let it do only this; that was the plan. It still does this better than anything I know of, but much more. So when used as intended, judiciously, without over-relying upon the gain knob, it is one of the greatest pedals ever made, still. I sent three pedals back to the store last week. This one stays. If it was hype, I'd tell ya. I have no interest in starting a 20 page thread about the Klon, and I've read all the others here. I just want to give my honest assessment. I hope it helps.
