I've been playing bass for nearly 5 months, and I play a 4 stringed Memphis. I am wondering what kind of strings would work for me, if I'm trying to get a heavy metal sound? And is it normal for my strings to 'buzz' when I hit a string? It seems as if the only problem is on my E string. The others sound great, and yes I have them tuned properly to standard tuning. (E,A,D,G) Can anyone help?
