1981 Inventions is a boutique effects maker best known for the DRV family of drive pedals. The DRV2 sits between overdrive and distortion, with a responsive gain structure that can stay articulate at lower settings and turn compressed and aggressive as the control rises. Its appeal is the way it preserves pick attack while adding harmonic density, making it useful into clean amps as well as already-driven rigs. The catalogue also reflects a deliberately compact, pedalboard-minded approach rather than a sprawling effects range.
