With a circuit inspired by the Klon Centaur, the Bondi Effects Sick As Mk3 is one of the most popular overdrive pedals in its category.

It features a toggle switch that controls the amount of headroom and character of the drive, and an extra Bass knob for added versatility. Both EQ knobs allow 15dB of boost or cut.

Mk3 keeps the same tone and look as the previous versions but features several improvements, including 18v internal voltage for extra headroom, better input protection, optimized power delivery network, reduced noise floor and quieter true-bypass switching.

Dynamic and natural sounding, like all Klones, the Sick As can do all sorts of things in the low-gain environment, acting as boost, overdrive or a blend of the two.

Here’s the first video of it, we added it to our comprehensive article about the best Klon clones.

Bondi Effects Sick As Mk3, Builder’s Notes

What’s new with the Mk3 Version:

• Same classic Sick As sound
• Robust power input protection
• Optimised power delivery network
• Reduced noise floor
• 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.
