The DOD 270 A-B Box is a relatively simple (passive operation) accessory allowing one to switch between two audio inputs to one output, or one input between two outputs. The 270 was introduced in the 1970s and was one of three accessories retained as part of the "AC" series when DOD discontinued their initial series of effects pedals in favor of the FX-series in 1982. At least six cosmetic variants were produced, including the final VAC series, which was produced into the early 2000s.
