Jupiter-50 pitch bender detuned


so I have this problem of my “joystick” not holding tune anymore. Bought the Roland 2nd hand few years ago. It doesn’t feel too ankward, but can’t hold tune anymore. Should ordering a new assembly fix it, or perhaps just the spring?

I’ve opened the bottom twice to remove the dust, it does not help. Here’s a reference of how it sounds. Kinda like that famous Van Halen “Jump in Pitch”. :stuck_out_tongue: Also, any estimated shipping time to Finland? Cheers!
