harby pedals centauri Harby Centauri Modified – Angel City Guitars

Modernized

The original Centaur’s components were attached to the circuit board using “through-hole” techniques, with pins that go through the circuit board and are soldered on its underside. This process got the job done, but it was expensive and time-consuming. Eventually, Bill Finnegan began producing his pedals using surface-mount technology (SMT), attaching the components directly to the circuit board’s face. 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 it’s being used to create distortion.” As a tribute to his insight, the Centauri uses only 1N34A diodes, with an original forward voltage of 0.35v (±15%). It’s also built using the original Centaur circuit board layout and features its buffered bypass, rather than the more modern true bypass.

Technical

• Original Centaur circuit with some modifications.
• *Clean knob: achieve the perfect balance between the cleaner signal of the gain stage and the harmonically rich overdrive signal of the gain stage. The clean knob provides you with unparalleled tonal control, allowing you to dial in just the right amount of grit while retaining the clarity of your core sound.
• *Original/JB(Phat) switch: Jeff modded his original Klon Centaur to allow more guitar low-frequencies into the circuit. Whether you’re laying down a solid rhythm or letting your leads soar, this switch ensures your sound remains punchy and full-bodied. This mod is subtle, but allows more bass to travel through the circuit and makes the circuit a little less thin sounding.
• *Germanium/LED switch: tailor your overdrive texture to match your playing style using the Germanium/LED clipping diode switch. Toggle between the germanium diodes to keep it authentic to the original Klon Centaur/KTR or the added LED diodes for a more gritty, harmonically rich overdriven tone. From smooth and creamy to edgy and aggressive, this switch lets you sculpt your sound with precision.
