A Klon Centaur overdrive pedal and Dumble guitar amp are two pieces of gear that just about every electric guitar player would love to get their hands on, but for 99 percent of guitarists there are two pretty big obstacles in the way: they’re both incredibly expensive and very hard to come across.

Crazy Tube Circuits seeks to solve such issues with the Unobtanium – a two-sided overdrive that looks to obtain the unobtainable and cram both Klon and Dumble tones into one compact pedalboard-friendly unit.
