Replacing a well-worn original part is as easy as looking up that part in this category, and there are plenty of replacements to choose from, especially for woodwind parts that are prone to wear. Take corks, for example - they have to stand up to repeated assembly and disassembly of the instrument, and they won't last forever. When the fit is no longer snug enough, go ahead and swap those out for something new, like the Valentino Synthetic Clarinet Joint Corks or the Valentino Sax Neck Corks.
Another part that needs changing frequently is the set of pads that cover the sound holes. And these don't necessarily have to be worn-out to swap, either: you could choose to change your instrument's pads to higher-quality ones, such as the Selmer Paris Saxophone Pad Sets, to help your keys feel more responsive or to make them more resistant to moisture. There are other accessories to go on and around the keys as well, like the Ridenour Clarinet Thumb Saddle and the Bo-Pep Flute Finger Saddle, which will make your instrument more comfortable to handle and play.
All these examples are just a small sampling of what the lineup of woodwind parts has to offer. So go ahead and take a close look: no matter what sort of woodwind you play, this is the place to find the bits and pieces you'll need to keep it performing great! And who knows - you might also discover a few accessories that go above and beyond standard parts, providing a level of personalization to make your instrument truly your own.
