Most, almost all of my harps are the 70s GM type. You can't easily take them apart. In fact, I got notes stuck on my G GM, it was going bad and I finally had to replace it. Is there any good info out there on retooling the nail holes to screw holes so that these harps can renew their lease on life? Could have sworn I saw an article on that some where?
Other wise I am assuming a denture tab is a soak solution and one that would be useful for those old harps which are so hard to take apart.
OK, maybe the way is here:
