I have a Johnson Deep Body A/E 4 string bass. JG622E. I have broken my E string and need to buy more strings. Thing is I have no idea what kind of strings belong on that. They are silver and metal (nickel maybe?). Do I need to stay with the exact same kinds of strings, or can I go with bronze wound strings? The reason I ask is that when I first broke it, I was going to put the E string from my Fender Electric on there and I happened to call a friend and he basically told me that would jack up my intonation. So now I want to make sure I'm not gonna jack anything up. I have looked on the Johnson web site and even emailed them, but, alas, no response. Help, please...I'm a night owl and when my roommates are sleeping I need to play my acoustic.
