Featuring rare NOS Mullard/Valvo OC45 germanium transistors for organic compression, increased gain, and sustain.
"The main composition has stayed the same as the standard version of Unobtanium that we released back in December 2022. A recreation of the Klon style overdrive true to the last detail finds its place at the right section of the pedal while the left section features two Dumble style amplifier voicings, the most unobtainable tube amplifiers in the world."
For the RAW edition, Crazy Tube Circuits added a couple of ingredients to the clipping section of the K side: a set of hand-selected New Old StockMullard/Valvo labeled OC45 germanium transistors from the 60s. They tested many germanium transistor types and found that the OC45 transistors added a supernatural feel with organic compression for increased gain and sustain. The standard sounds are still there in the stock setting where you listen to germanium diodes clipping like in the original unit.
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.
The RAW version will be built in limited quantities and stay out there for as long as we have stock of the NOS Mullard/Valvo OC45 germanium transistor. It is now available through our online direct store and dealer network.
Street price: 339 Euro, 349 USD

HI POWER is inspired by the two British tone machines that helped shape the sound of Pink Floyd’s Wish You Were Here.
On the right side of the pedal, you will find a recreation of the Colorsound Power Boost featuring the true-to-the-original spec BC184 transistors running on 18V DC (via an internal voltage booster circuit) and the ultra-flexible 2-band Baxandall EQ circuit. We’ve added extra modern features, like a bypassable master volume control, a reverse-log gain control to ensure better sweep and transition from clean to mean(compared to the original’s linear taper), and a toggle switch the engage the latter higher gain / lower headroom version of the original boost circuit called Overdriver.
On the left side of the HI POWER you will find an all-analog circuit set out to emulate the sound and feel of a Hiwatt amp. Following the path of the famed British tube amplifier, our circuit offers an authentic amp tone and feel. From the big bold high-headroom clean sounds to the face-melting crunchy tones.
True to the last detail we have included the full EQ section along with a presence control located at the negative feedback of the power amp simulation circuit. A headroom toggle switch selects between the high headroom 100w power section provided by a quartet of EL34s or the lower headroom and compression provided by a 50W power section with a pair of EL34s when hit hard. Similar in operation to the originalamp design the master volume control was designed to produce more gain at higher settings.
Key Features
- All-analog dual booster/overdrive – amp in a box
- Recreates the overdrive tones of the legendary setup used by David Gilmour in the recordings of Pink Floyd’s Wish You Were Here album.
- Right side: faithful reproduction of Colorsound Power Boost / Overdriver circuits
- Left side: 100W and 50W Hiwatt voiced clean / overdrive circuit.
- Passive series effects loop to connect pedals between the two sections or use them separately as independent effects.
- Independent operation of the BOOST/OVERDRIVE and AMP sections
- Click-less true bypass design via high-quality relays for each section.
- 2 Footswitches / 2 Status LEDs - one for each effect section.
- Power-up bypass/engage preset function for the footswitches.
- Top mounted jacks
- Power Supply: 9V DC, center negative power supply (not included)
- Made in Greece
We’ve taken our design a step further by adding a switch to select between input channels. You can select between the full frequency response of the normal channel of the amplifier, the increased presence and tight low end of the bright channel input, or the enhanced frequency response and added gain of those inputs linked together.
Like our other dual overdrive/amp-in-a-box designs we have also included 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.
Suggested Selling Price is 279 EUR / 289 USD. Available now with our authorized dealers all over the world.

You could win a Stardust V3 form Crazy Tube Circuits in today's Stompboxtober giveaway! Enter below.
Crazy Tube Circuits Stardust V3
Stardust V3 was designed to capture the sound and response of 3 distinct maxed out and ready to sing blackface amplifier models. An all-analog signal path with discrete gain stages featuring MOSFET transistors, provides juicy overdrive tones with great note separation that clean up to that sparkly sound that we all love and heard in recordings of the past. Set gain and tone and control everything from your guitar. Sparkly clean to crunchy mean are all there.
You can select the blackface amplifier voicing via the onboard toggle switch
BSM: Voiced after a blackface amp head that was primarily targeted for bass guitar players but got famous for electric guitar classic rock tones.
VLX: Voiced after a chimey 2x10” combo offering the perfect amount of controllable crunch
DLX: Voiced after one of the most popular low wattage 1×12″ combo amps that have found their way in countless recording studios and clubs around the world.
