If you are up to it, changing out the 4558 (basically a dual 741) op amps, ceramic and tantalum caps will make a huge difference.
The electrolytics used are also poor by today's standards. They were good for ten years tops and are undoubtedly "dried out".
You can do all of the above for less than $40. "Boutique" caps. are not at all necessary, imo.
