Unobtanium

The Unobtanium by Crazy Tube Circuits is an overdrive pedal that combines the characteristics of two iconic amplifiers. It features a faithful reproduction of the mythical overdrive circuit with a wide gain range control, active treble control, and a volume knob for overall output. The pedal also includes a toggle switch for selecting between original buffer bypass and true bypass, as well as stock clipping/compression or enhanced gain and headroom/output.

The left side of the pedal houses a D-style amp-in-a-box overdrive with controls for gain, volume, tone, and emphasis. It offers two distinct D-style overdrive circuits: SSS for clean and transparent overdrive with natural organic compression, and ODS for higher gain overdrive with enhanced mid frequencies and harmonic overtones. The pedal also features an external footswitch input to select amplifier voicing, internal trimmers to adjust EQ and volume boost, and a passive series effects loop to connect other pedals between the two sections or use them separately as independent effects.

The Unobtanium runs internally at 18V DC for higher headroom and tube-like performance, and it is designed with top-mounted jacks and a click-less True Bypass design via high-quality relays. The pedal section on the right side includes a K-style overdrive circuit with germanium diodes, while the amp section on the left side includes a D-style amp-in-a-box overdrive. The pedal also features a passive serial effects loop for looping in other pedals between the pedal and amp section.

The Unobtanium is manufactured in Greece and is designed for use with a 9V DC mains adapter. It does not support battery operation. The pedal's dimensions are 147 x 103 x 65 mm, and it weighs 510 g.
