Crazy Tube Circuits Unobtainium RAW Dual Channel Amplifier Overdrive Pedal

The Unobtanium RAW is a dual overdrive pedal an all-analogue faithful reproduction of the legendary Klon Centaur overdrive voicing on the right, and two unobtainable tube amplifier voicings on the left.

Key Features

• Legendary Tone – The faithful K-style tone that comes from this pedal is designed to inspire.
• Pure Dumble Overdrive – With the help of the ‘60s NOS Mullard/Valvo OC45 Germanium Transistors, you can be sure that this pedal delivers authentic Dumble!
• Passive Effects Loop - The passive effects loop gives you the option to connect your beloved pedals between your booster/overdrive and amp in a box or use the two sections as separate and independent effects when using an external bypass switcher/looper.
• Power Up Bypass/Engage - This is a preset function for footswitches. That way you can select which state your pedal will go to when you plug in the power supply.
• True Bypass/Buffered - Buffered or True Bypass Operation means you can fit this pedal in your signal chain easily.

K-Style

On the K-style side of the pedal, Crazy Tube Circuits has added an authentic voicing to the clipping section. This is a set of hand-selected Mullard/Valvo labelled OC45 germanium transistors from the ‘60s. This adds a supernatural feel with organic compression for increased gain and sustain. This is the first Klon-type circuit to feature germanium transistors in its clipping section!

Dumble Overdrive

The amp-in-a-box side of the RAW version is 2 Dumble voiced overdrive circuits and is glassier and punchier than the standard version of this pedal. Think of singing blues rock and classic rock sounds that cut through the mix, flawlessly performing with all kinds of different guitar/pickup combinations.
