To be honest, I'm not sure how long the issue has taken to manifest itself on mine. I've had it about 20 years from new, and only noticed the lift when reading about it on here!
I have had a quick look at the cost of replacement non-original bridges - the cost and presumably quality vary a lot. There is always the option to go down the Geddy Lee route and replace with a Badass bridge with a shaped surround to maintain the overall look of the bridge......I have one of these on one of my jazz basses that's not currently seeing a lot of action 🤔🤔
