hi talkbass bros, here's the deal: Some guy is selling me his 5 strings peavey millestone bpx and he sent me some pictures of it; the one that i attached to the post is the one that worried me. i have some questions about it 1. is there a way to clean the rust from the metal parts? 2. is the rust a big deal? 3. How much should i pay for it? thanks.
