What warranty? This bass was bought via Mark from Sweetwater or some other online retailer - whatever warranty there is (if not already expired) sure won't apply to me as a German resident and shipping it back to Mark to have him return it is a hassle not worth it. If I had bought it in Germany, I'd attempt a warranty return just for the experience of it (and report about it here). But in essence it's a minor repair/quick fix.
I'm philosophical about it, a question of statistics. It's not like my "rubberneck" 8-string Ric which has been a source of constantly renewed grief from the first day I had it.
The material on the Novoselic is dark-stained obeche,
http://www.wood-database.com/lumber-identification/hardwoods/obeche/the name itself already raises suspicions ...
I wouldn't be surprised if it had something to do with it, but I'm not knocking Gibson because of it, they had to go for alternative woods at the time and you only learn from experience.
"i think you expect too much, bass wise, from anything named novoselic"
Nofi, wiser words (albeit post-acquisition) have never been spoken. Don't get me started on Nirvana. The bass is probably their revenge for me being so oblivious to their lasting influence. Darn bar-chord-shovers without the most basic inderstanding of the European rules of harmony. Should have gone to summer school with Wishbone Ash.
