After finally being able to find the same magic diodes used in the original Klon Centaur, Rockett have been fine tuning the circuit so that it matches the source material: a real gold Klon Centaur. Rockett tuned the Ikon to its Centaur until the differences were 100 percent indistinguishable. The sound is a hair more compressed than the silver Archer and fuller sounding with the Gain knob dialed back-or "boost" mode-which is how a majority of players use their klones. When set to full gain-or "drive" mode-the Ikon exhibits a smoother, gently compressed clipping section, indicative of the original Centaur tone but sorely lacking from the abundance of klones on the market. The Treble knob keeps all the frequencies in check, and is a godsend for players using a Les Paul or other humbucker-equipped axe. Just like the original Centaur, a charge pump circuit is utilized to internally bump the voltage from the nine-volt input up to 18 volts. This helps create the legendary headroom for which the Klon is renowned, and it is also why the Klon stacks so well with other pedals.
