list price 1977: 130 DM
collectibility: very high
interesting side note: the very first OD-850 came in a repainted green housing (see last photo in gallery) - presumably these were unbranded "The Dirt Box" (more) before that were on sale in the U.S. for a short period in 1976.
In June 2016 Ibanez reissued this first version (v1) of the OD-850. You can easily distinguish the originals from the reisues as the new ones have LED and DC power jack added. Underneath the nut holding the footswitch sits a (today almost inevitable) white plastic washer.
