Description

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

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

For the RAW edition, Crazy Tube Circuits has added a couple of magic ingredients to the clipping section of the K side: a set of hand-selected New Old Stock Mullard/Valvo labelled OC45 germanium transistors from the 60s. The engineers at Crazy Tube Circuits 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 sounds are still there in the stock setting where you listen to germanium diodes clipping like in the original unit.

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 guitar/pickup combinations. Think of having the rock/jazz toggle switch set in the rock 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 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 in the power supply. This function comes in especially handy for people that use remote pedal switchers/loopers, as they only set the state of the pedal once and then operate from the controller.

The RAW version will not replace the standard one, which will continue to thrive. It will be built in limited quantities and stay out there for as long as Crazy Tube Circuits has stock of the beautiful NOS Mullard/Valvo OC45.
