I have been wanting an Archer after seeing a buddy of mine use his and after finding out Jonny Two Bags uses it with his Social D rig. Although not the silver they use, I was able to grab the gold Ikon at a good used price. Picked it up, brought it home, and messed with it. I can definitely say this is a bad muthafuckin' pedal. It is very transparent and does not color you tone at all; rather, it sweetens it. It is you having your cake, with sprinkles, and being able to eat it. All of it. With the output up and gain down, it serves as a clean boost to push your sound. And as soon as you turn up the gain, it can take you from a nice lil' crunch to a roaring overdrive (which surprised me considering most Klon/Klone users appear to play dad rock). The treble adds even more flavor to your tone as well, and add a nice little chime when used on the clean channel. Overall, the Ikon is fucking worth it - I don't see myself getting rid of this pedal at all. Get one. Do it. It's awesome.
Full disclosure; I've known one of the owners since HS, '82. Having said that, I read all the hype and so on, about this pedal, the history, and the Klon. Simply put, this pedal is a must have, as it handles a few chores very well; OD and Boost. Rock solid, quiet, smaller real estate, and most of all just fantastic sounding drive. Transparent? What's that. I'll this; now matter how high the gain, I can still hear my guitar and amp. Important? You decide. It's gritty and smooth, and pushes a slightly overdriven amp to nice breakup. My rig; Laney VC30 2X10, Fender Blues Jr. Squier J. Mascis JM, Fat Tele with BG Seymour stacked in the bridge and a Pearly Gates in the neck. Many pedals, I usually have my Archer on at all times, with gain at 9 o'clock, volume at 10 o'clock and tone at about o'clock.
Klon in a box type pedal. I use it just as a lead boost on my main board so the gain is pretty much all the way down. It does have more sounds that also sound great as I have messed around with it by itself.
