What's new with the mk3 Version:

• Our quietest ever true-bypass switching

The Sick As Overdrive is a diversion from the well-worn path, taking its basic structure from the Klon Centaur® but with some major improvements for the modern player. The gain control serves a dual purpose— as the gain is increased, the ratio of gain-to-clean tone increases as well. This ensures that when the gain is rolled off, the tone never becomes muddy and unpleasant. You can control the amount of headroom and the character of the drive with the toggle switch. Choose from a more compressed, mid-range focused tone or an open, transparent, rhythm tone.  The tone circuit is a powerful, two-band active EQ circuit capable of boosting or cutting the bass and treble frequencies up to 15dB for maximum versatility. The voltage is also boosted internally to 18V for increased clarity and headroom.

• Clean Boost, Overdrive or a blend of the two.

• Toggle switch controls the amount of headroom and character of the drive.
