Arp Odyssey restoration & mods


A MK I (white-face) Arp Odyssey presumably manufactured towards the end of 1973. When I bought it, it was in pretty bad condition internally, so comprehensive repairs were needed. I also chose to re-work the entire audio path whilst at it. Restored to fully functional state late 2007, mods added during 2008, additional repairs between 2010 – 2011.

      Don’t have my box at hand to check it, but I think I used a generic TL074. Any quad opamp should be fine :)
