nickel/silver frets This is a common cosmetic problem with nickel/silver frets. If you want to avoid it, I would recommend getting guitars with stainless steel frets in the future. With SS frets, some people hear a difference, for example, James Tyler, while other don't, such as Tom Anderson. I persoally don't hear a difference. Your question can be easily addressed. You can do this yourself. You will need masking tape and rubbing/polishing compound. First: next time when you change strings, remove all strings and use the masking tape to mask off the fretboard. The purpose is to prevent the compound from getting in contact with the fretboard. Second, with the masking taken care of, take a small amount of compound, distribute it evenly on a piece of cloth (your old T-shirt works fine), and then you can start polishing all frets. You won't hurt anything on your guitar by doing so. But if you are timid about doing this yourslef, take your guitar to Jeff or any other reputable guitar techs. Peace. Play on.
有人用膠帶~我是先把一張空的護貝紙給護貝~變硬之後 中間挖空讓fret剛好可以套進去~還可以重複使用 再用磨指甲的電動鑽子~換上棉花棒頭 沾一點點Winnel或電鍍膏去研磨~ 超快又超亮 不過注意的就是，以上的東西研磨之後 都會變成黑色的液體唷 被指板吸收進去之後就清不掉了 請小心 怕的話就買塊拭銀布慢慢推吧 不過大概推個三根fret就會想罵髒話了 - 不過我自己的吉他都不會這樣做，因為我無所謂 都是幫別人清的...
