The Cosmic Terror Droog is a dual-function guitar effects pedal that combines a high-gain overdrive with an integrated momentary feedback looper. The overdrive circuit is based on the famous Zendrive design, specifically modified to provide better low-end clarity for down-tuned guitars and bass. The unique feedback section allows users to patch other pedals into a dedicated loop, which can then be forced into self-oscillation via a momentary footswitch for chaotic noise effects. Each unit is handmade in Germany with a chemically etched, black-patina metal enclosure and a hand-oiled finish. The pedal features top-mounted jacks for easy pedalboard integration and is designed for experimental, doom, and drone music styles.
