The 1981 Inventions DRV MONO is a distortion pedal built on the standard DRV circuit, the same design as the company's regular DRV. The maker describes it as "subtle, unique, and has some incredible engineering behind it from some very talented friends." It was offered as a limited run at $150, which the maker framed as $100 off the regular DRV price of $250, and it is now sold out.1
Circuit and sound
The DRV MONO uses the standard DRV circuit, so it carries the same core design as the regular DRV rather than a new or modified one. The maker's own description of the sound is that it is subtle and unique, with what they call incredible engineering behind it.1
Enclosure and colorways
The MONO introduced a new enclosure type for the DRV family. The maker says it is very similar in size and shape to the enclosures used for the MMHMM or MOO DENG versions, but slightly taller. The finish is powder coating with a slightly textured surface and UV printing.1
Two colorways were offered:
