The Klon Centaur may be the most heavily sought after pedal in the history of rock and roll — and with good reason. It was developed in the early 1990s by Bill Finnegan, and a few thousand units were produced in that decade before production ceased. Guitarists adored this pedal for what they described as “transparent” overdrive — a gain boost that didn’t color the original signal of the guitar.
When production ended, the hype began. Finnegan was so protective of his proprietary design that he covered his circuit boards in black goop so the pedal could not be reverse-engineered. So when he stopped making them, they became very scarce, and prices skyrocketed. While many reissues attempted to capture the magic of the original unit, true believers still seek out the mojo of those 90s circuits, and original versions can fetch up to $3,000. The hype around these pedals was so profound that it apparently caused Finnegan some heartburn — when he finally reissued the pedal he had each unit prominently inscribed with a poem of sorts:
Kindly remember:
That the ridiculous hype
That offends so many
Is not of my making.
Because of this history, true guitar gearheads celebrated when Trey added an original Klon to his rig during the major overhaul that led up to the 2016-2017 New Year’s Run. It appeared to be there as a replacement to the H&K Tube Factor, a tube-based pre-amp pedal that had been in the rig since Fare Thee Well.
For the Colorado 2019 Tab run, Trey used the J Rockett Archer Ikon in place of his Klon. He had previously used this pedal as a backup and off-stage. It’s an excellent Klon substitute.
