I overhauled this clarinet about 5 years ago using cork pads in the upper joint, felt pads on the ring keys and leather pads in the lower keys. Before posting for sale I removed all the keys, oiled the bore and keys and replaced 3 pads. Both joints seal very well and it plays very easily with a great tone. I expect the current pads to last another 5 years with only minor play conditions once a year.
