Crazy Tube Circuits Unobtanium Raw Dual Overdrive (Limited Edition)

A rare sonic element with alternate refinement – meet the new Unobtanium RAW edition!

The composition has stayed the same as the standard version of the pedal: A recreation of the Klon Centaur overdrive true to the last detail finds its place at the right section of the pedal while the left section features two Dumble amplifier voicings, the most unobtainable tube amplifiers in the world.

For the RAW edition we have added a couple of magic ingredients to the clipping section of the Klon side: a set of hand selected New Old Stock Mullard/Valvo labelled OC45 germanium transistors. This is the first Klon-type circuit to feature germanium transistors in the clipping section. We have tried many germanium transistor types and found that the OC45 transistors added a supernatural feel with organic compression for increased gain and sustain. Fear not - the standard Klon sounds are still there in the stock setting where you listen to germanium diodes clipping like in the original unit. (Note: the sonic difference in clipping/voicing is most noticeable in higher gain settings. Volume knob might need to be readjusted when changing clipping setting).

The amp-in-a-box side of the RAW version is glassier and punchier than the standard version. Think of singing blues rock and classic rock sounds that cut through the mix, flawlessly performing with all kinds of different guitars/ pickups combinations. The sonic difference between the RAW and the normal version is similar to the effect of the onboard rock/jazz toggle switch found on Dumble amplifiers. The rock setting would be closer to the Raw version while the jazz setting would be closer to the jazz setting.

As with the standard version, Unobtanium Raw features a passive effects loop to give 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. Note that all pedals inserted in the passive effects loop are still in the signal chain when any or both sections of are in bypass mode.

Unobtanium Raw features a power-up bypass/engage pre-set function for the footswitches. That way you can select which state your pedal will go to when you plug the power supply. This function comes in especially handy to people that use remote pedal switchers/loopers as they only set the state of the pedal once and then operate from the controller.

Right side: faithful reproduction of the mythical overdrive circuit including the fabled germanium diodes

• Wide gain range control: from transparent boost to high headroom overdrive
• Treble control is an active circuit to boost or cut treble
• Volume knob sets overall output. Huge amount of dB boost available
• Toggle switch to select between the original buffer bypass to add clarity and run long cables or true bypass
• Toggle switch to select between stock clipping (germanium diodes) or enhanced compression, gain and sustain (NOS Mullard/Valvo OC45 germanium transistors)

Left side: D-style amp in a box overdrive

• Gain control: from clean boost to sweet singing overdrive
• Emphasis control is a pre-drive EQ to control presence and bottom end response
• Tone knob controls the amount of post overdrive high end frequencies
• Volume knob sets overall output. Match bypassed volume or use as a clean boost or preamp
• Toggle switch selects between 2 distinct D-style overdrive circuits
• SSS: clean and transparent overdrive with natural organic compression
• ODS: higher gain overdrive with enhanced mid frequencies and harmonic overtones
• External footswitch input to select amplifier voicing (bypasses on board toggle switch)
• Internal trimmers adjust EQ and volume boost of D-style overdrive voicings

Passive series effects loop to connect other pedals between the two sections or use them separately as independent effects. Runs internally at 18V DC for higher headroom and tube-like performance. Top mounted jacks. Click-less True Bypass design via high quality relays.
