So my E string just poped as I was practicing. It was the E string which I had tuned down to B and it was a 130 gauge. My strings were Rotosound 65 to 130. I'd say I had these strings on my bass for about a month and a half now. I like to play alternative metal and play in drop B. I'm about to put on my GHS Boomers with the E string being at 115. Any one have any good suggestions on some bass strings with a low gauge like from 115 to 130 for a 4 string that are reliable? Oh my GHS Boomers have been more reliable than my 130 Rotosound ones but I like the 130 gauge and the low sound it makes, I just don't like them breaking after a short while.
