Cleaned keybed contacts, individual keys, pots, deoxed tak switches (helped some) and i had to drill tiny hole into each one and inject deoxit. (Will have to replace them later), replaced a kay and a button, soldered bad joint and battery and full cal&tuneup whatever i could understand from the service manual. That was the biggest challenge of all!
Mods: the post fx filter bypass, leds
Planed mods: red oak panels, vynyl overlay, more electronic mods :) replace that cord with standard one thats all for now
