Say hello to Unobtanium, a rare sonic element born out of legendary tones! With Unobtanium, a mythical overdrive meets the sound and feel of two iconic amplifiers. Crazy Tube Circuits have accurately recreated the circuit of the high-headroom overdrive with the magic blend of clean and overdriven tones and added extra features for versatility.
The amp-in-a-box section uses an all-analogue circuit to capture the essence of two legendary D-style tube amplifiers — delivering anything from tube-like, compressed fat cleans to sweet singing overdrive with blooming harmonic overtones. Combine both sides for near-infinite smooth sustain and to enter sonic bliss, while a passive series effects loop gives you the option to connect your beloved pedals between the overdrive and amp section; building your ideal rig.
Key Features
- Dual overdrive with independent operation.
- Two legendary sonic elements combined in one device.
- Right side: K-style pedal overdrive circuit including the fabled germanium diodes.
- Left side: D-style Amp in a box overdrive.
- Passive series effects loop to connect other pedals between the two sections or use them separately.
- Runs internally at 18V DC for higher headroom and tube-like performance.
- Exceptional pick attack response — almost infinite smooth sustain when both sides are combined.
- Top-mounted jacks for easy pedalboard mounting.
- Click-less true bypass design via high-quality relay.
- Use only 9V DC center negative power supply (not included).
- Modest current consumption of 83mA.
- Pebble grey die-cast enclosure with black ink in old-school type print.
- Made in Greece.
Right Side Controls
- Controls: gain, treble (tone), volume, bypass mode and clipping/compression.
- Wide gain range control, from transparent boost to high headroom overdrive.
- Treble control is an active circuit to boost or cut highs.
- 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/compression or enhanced gain and headroom/output.
Left Side Controls
- Controls: gain, emphasis, tone, volume, amplifier voicing toggle.
- 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 two 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 onboard toggle switch).
- Internal trimmers adjust EQ and volume boost of D-style overdrive voicings.
