I compared an early gold Centaur and the KTR extensively, as well as many of the usual Klones. I kept the OG gold. The KTR is very close, but it's a bit different. Maybe it's the fact that the Centaur is 20+ years old or just the variance in the tolerances of the individual components in that particular pedal. Whatever it is, it's the BEST Klon or Klon-type I've had (between 2 silver, 2 gold, and many Klones). It just adds a small amount of foundation to the bottom of my tone that I love.
