via the seller: "Here we have an original early 70's Arp Odyssey mk1 (with Arp's 4035 moog filter) in good condition that has been professionally serviced and calibrated recently. It sounds and works just as good as if it was brand new. This is a big deal since cleaning the sliders on these instruments is very time consuming. You must disassemble the instrument to do this properly. I had an Arp expert go over every inch of the machine and it is ready for the stage or studio.

This machine is not mint but it has been pro owned it's entire life and looks great. It had two mods in the 80s that I had reversed back to original specs. Two small holes were left behind that were covered with small plastic Arp style plugs. The odyssey is one of those synths that is easily modified. I had it put back to 100 percent factory spec. One mod I did later was to have the machine upgraded to the more musical moog style filter of the mark II machine. All mods were performed and/or reversed by the top Arp tech of the day.

So what you are buying is a Mark 1 machine that has recently been serviced, cleaned, calibrated, and given a clean bill of health; with the moog style filter of the mark II machine (Arp's 4035 filter only found on the black and gold mkII machines). You can easily change the filter back but after owning all the Odyssey machines, the moog style filter sounds best to me, so I had the upgrade done to all my machines."
