Up for sale, a 1980s Boss Digital Delay model RDD-10 in excellent condition and in perfect working order. The RDD-10 is part of the Micro Rack series, featuring continuously variable delay times between 0.75 to 400ms with flat frequency response up to 15kHz. The rack features a Fine knob to adjust the delay time selected, and the onboard modulation offers everything from more chorus-like shimmer to very wide and deep waves of vibrato. There is additional control over the delay Tone and Level, and the rack boasts 1/4" outputs for the dedicated delay signal as well as a mix between the dry and effected sound.

The rack also employs a 12-bit PCM system plus analog logarithm compression, and this rack unit is also identical in features and function to the RDD-20 from the same Micro Rack series, sharing the same PCB.

Cosmetic wear on the unit is limited to a handful of minor nicks on the enclosure, and some general oxidation of the baseplate. The graphics are pristine, and the original multi-colored knobs are present.
