An original gold Klon Centaur from the master himself Mr. Bill Finnegan. This much talked about overdrive/booster has lit forums ablaze but the fact is once you plug your guitar and amp into this pedal the world goes away and you just want to play guitar. The Klon Centaur is perfectly at home boosting a clean signal or causing the signal to overdrive. It becomes more of an extension of your guitar sound and sounds so life like that you tend to forget that a pedal is on at all.   Oh, and one more thing... This pedal was owned by none other than "Big Al" Anderson of the legendary Americana/Roots Rock Band NRBQ! Serial number: 780
