Overdrive / Boost / Buffer
Modified, but faithful to the original.*
Features
Modernized
The original Centaur's components were attached to the circuit board using "through-hole" techniques, with pins passing through the circuit board and soldered to its underside. This process got the job done, but it was costly and time consuming. Eventually, Bill Finnegan began producing his pedals using surface mount technology (SMT), attaching components directly to the face of the circuit board. This is the method we used to design the Harby Centauri.
True to the original
Bill Finnegan once said of his 1N34A germanium clipping diodes that they are "...the most important factor in how the circuit sounds when used to create distortion." As a tribute to its insight, the Centauri uses only 1N34A diodes, with a stock forward voltage of 0.35V (±15%). It is also built using the original Centaur PCB layout and features its buffered bypass, rather than the more modern true bypass.
Technical
Original Centaur circuit with some modifications.
* Clean Blend Knob: Achieve the perfect balance between your original signal and harmonic-rich overdrive. The Clean Blend knob gives you unparalleled tonal control, allowing you to dial in just the right amount of grit while maintaining the clarity of your lead sound.
*Which Bass Boost Switch: Do you want a thicker, more powerful bass response? Engage the bass boost switch to inject your sound with an extra dose of low-frequency goodness. Whether you're establishing a solid rhythm or letting your leads soar, this feature ensures your sound remains punchy and full-bodied.
*LED Clipping Diode Switch: Adapt your overdrive texture to your playing style using the LED clipping diode switch. Switch between germanium diodes to keep it authentic to the original Klon Centaur or added LED diodes for a more grainy, harmonic-rich overdriven sound. From smooth and creamy to edgy and aggressive, this switch lets you sculpt your sound with precision.
