Dual Overdrive with Two Independent Sections!
Unobtanium – a rare sonic element drawn from legendary sounds. A mythical overdrive meets the tone and character of two iconic amplifiers. Crazy Tube Circuits has precisely recreated the high-headroom overdrive circuit with its magical blend of clean and distorted tones and enhanced it with additional features for greater versatility.
The amp section delivers the character of two legendary D-style amplifiers with a fully analog circuit – from tube-like, compressed, thick cleans to singing overdrive with sparkling harmonic overtones. Combine both sides for an almost endless, smooth sustain and experience pure tonal bliss. A passive, serial effects loop lets you insert your favorite pedals between the overdrive and amp sections, so you can craft your ideal setup.
Features
- "Klon" (Pedal) and "Dumble" (Amp) combined in one unit – ultra-rare sonic elements usually "unobtainable"
