The mouthpiece was not on the cap when i took the picture. (sorry if im misunderstanding you) Also is there anything I can do about it?That looks like the cap, not the mouthpiece itself. The cap is just lacquered brass which can tarnish. Welcome to the world of brass instruments. My 50 y/o MkVI looks like James Cameron found it on the Titanic.
I thought I bought it new from WWBW but it came with scratches and once again it is not a cap it is just zoomed in on the mouthpiece. Does this affext the playing and can i fix it?Was it a new or used mouthpiece? An Otto Link is a gold-plated bronze mouthpiece so it doesn't rust. What you are showing looks like a lacquered reed cap as mdavej said. Any little scratch lets air/moisture get to the brass which starts corrosion under the lacquer that turns the lacquer brown.
So does this affect the sound?I have a couple of gold plated DG LT pieces that have this type of discoloration. It's not rust since there's nothing involved that would rust but more like imperfections in the plating that show up over time especially if the piece is handled. My feeling is this is the sign of a crummy plating job but I'm not an expert on electroplating so that's a bit of a guess. If you like the way the piece plays I wouldn't worry about it. The gold plating on most mouthpieces is so thin it begins to wear off within a year or two anyway.
No, as the others have said it's just cosmetic but it is a bit annoying especially if it begins to happen very quickly after you purchase the piece. The reason I think it's a poor plating job is because my gold plated JJ and SR Tech pieces have not done this. Like most things I suspect you get what you pay for in terms of plating jobs. Regardless, if you like the way the piece plays don't worry about it and just keep playing. You can't see the piece while your playing it and nobody else cares so don't obsess about it just keep practicing.So does this affect the sound?
Actually ........ https://theowanne.com/knowledge/the-vintified-finish/You have to earn that patina!
As far as I know, no one has yet began to market “distressed” mouthpieces like other products are sold. Pre-faded and threadbare jeans, for example. Fender has been doing this for years with electric guitars, and you pay extra for the worn-down finish they apply at the factory.
As has been mentioned, if your Link plays well for you and you’re happy with the tone, it’s a keeper, regardless of what shape the finish is in. It can be hit-and-miss with the facings on Links. You might exchange it for a nice new shiny one that doesn’t play as well as what you have.
