This is the tiny pedal which dethroned a giant. The Klon is famously a great "transparent" drive which is so rare they go for huge figures on the second-hand market. Yet Brian Wampler made his "klone" less transparent by adding extra chewiness (that tone you feel at the back of your teeth) and in blindfold tests this has proven to be the best sounding of the all the Klones on the market.
The best way for you to decide this for yourself is to compare it against all the other Klones we have on TonePedia which include an original Klon KTR!
