This module looks like it fell out of a time capsule and is an absolutely flawless, fully functional unit. All inputs, outputs and editing functions work perfectly. Comes with the factory rack ears, 3 soundpacks and samples that still amaze me! The ddrum AT module, produced in 1993, is considered a highly sought-after collector's item due to its limited production run (Less then 300 exist) making it "unobtainium" for most people seeking to purchase one today. You will not find a cleaner AT!
