General

Loaded with NOS Mullard/Valvo OC45 germanium transistors, the Crazy Tube Circuits Unobtanium Raw puts an original spin on the sound of the Klon and Dumble — two truly legendary pedals. This dual-channel amp-in-a-box/overdrive effect pedal shapes slightly rockier sound than the non-Raw edition and lets you use both channels independently or in series. You also get a passive effects loop for integrating your favourite stompboxes and, since this box of sonic tricks runs on 18 Volts, you can count on masses of headroom and an outstanding response. Each unit is painstakingly put together in Greece.

The Unobtanium Raw: From a Transparent Boost to Obscene Overdrive

The right half of the Unobtanium Raw is home to a K-style overdrive circuit with OC45 transistors for surprisingly versatile sound that can be accessed by flipping the stock/OC45 switch. The broad range of the gain control ranges from a transparent boost up to a rough-edged overdrive with lots of headroom and extra sustain, and you also get a mini-switch for toggling between true and buffered bypass. Over on the left, you'll find the D-style amp-in-a-box, which sets you up with a subtle clean boost that can be pushed all the way to lilting, tightened-up overdrive. Here, the Emphasis pot lets you tweak the presence and bass response in great detail, while the mini-switch can be engaged to select SSS mode for organic compression or ODS mode for more gain and more harmonics.

Wrote the following about Crazy Tube Circuits Unobtanium Raw Dual Channel Amp-in-a-Box/Overdrive Pedal

Tja, ik heb al een aantal pedaltjes met de zogenaamde Dumbele soud, maar deze dubbeldekker heeft nu precies het geluid die ik in mijn hoofd heb!! Voor een stratocaster is het een must. Ik gebruik dit met een Blackstar st-james 6L6 als en dat is een match made in heaven!!!Als het echt vetter moet met een Epiphone LP En een beetje gain staging bv. Unobtanium>Nobels Or-1X>greer amps lightspeed kan ik een heel breed scala van light gain tot vet oversturde lead tone uit mij versterker krijgen. Kortom deze krijg zeker een 12😉
