I got my protostar about a month ago brand new, and noticed more bearing noise out of the box then I was used to. It’s my first unresponsive, and not uncommon, I’ve heard. But I dropped it twice on a craft store while I was measuring it for a “Bloop” knockoff I was making. The next time I threw it, it was a LOT louder. I had never taken it apart, but have gone through about 20 strings on it.
After ordering a DV888, I decided to pull it apart. The bearing is firmly attached to one of the bearing seats (I think that’s the term). And no part comes completely apart from their respective halves without more force than I’m willing to give it.
Having never disassembled it before it made more noise, I don’t know what about this is common, or not. Any help is appreciated. And I apologize if this topic has been covered before, but I’ve done a fair bit of searching and couldn’t really come up with anything other than cleaning the bearing (which I have all the ingredients for other than the thin lube, though I have the Yomega brain lube that I used back in the day)
