hi all, I have a Grassi jade series alto sax. Problem is that some clumsy so and so stuck an ill fitting g# key touch and 2 roller keys that look gross. Not to mention the thumb rest at the back. My problem is that I require spare roller keys for these, a G# key touch and D key pearl and preferably a l/h thumb rest to improve the appearance of this sax as it bothers me! If anyone has the things I'm looking for please can you get in touch as i'd be happy to buy them - alternatively, where can I source them from as i want to keep it original?!
