@MAGOMAX1970 thank you for the info, in fact I noticed that this bass sound more heavier than a simply danelectro longhorn, it's more powerfull, didn't it? (sorry for my bad english)
This is a great video. In my opinion, (not counting 'influences') King Buzzo, Mark Arm, and Kurt Cobain were the (and in Mark and Buzz' case) are the fathers of 'grunge'.
