Hey there, Ok I have two questions and a thanks. I solicited string advice and based on the advice, just purchased a set of Chromes for my newest bass (my 2011 American Standard P). So far they sound great so thanks.. As I was stringing them up I know I was told to stretch them and I have done so but my question is how many times should this be done? Also as I was installing them, I used the string through body method and since this is my first bass to have string through, I was wondering what the difference is? Some people have told me it will give more sustain but is that the only difference?
