I have a Warwick thumb bolt-on 5-string. In the last 90 days I have gone through four G strings due to string breakage. Although I play pretty aggressively -- I do a moderate amount of pop/slap and tend to play hard with my fingers -- this just seems like an insane amount of strings breaking in a short period of time. I've been using good brands of strings (Warwick, Ernie Ball, Dean Markley) and I've not used the lightest gauges either. Reading the posts elsewhere in this forum makes me think that there might be a problem with the gauge of string I am using, my bridge, my playing style, or some linear combination of these. I know that sometimes situations like this point to a problem with the bridge, but when I look up-close at mine I don't know what to look for if I think there is a problem. Will something as seemingly minor as dust particles cause bridge problems, or would this only be caused by something big like a small piece of metal or plastic flashing sticking out of the bridge? Any ideas? PS: I wonder too if temperature might have something to do with this? Yesterday was the latest string-popping incident, and while I didn't really play that hard I did leave my bass set up in the church auditorium all day, and there was maybe a 15-degree temp difference during the day.
