I had a set of GHS Zakk Wylde Boomers and it messed up my guitar. Right now I have Ernieball 11 Gauge straings. I'm tryin to choose if I want to use GHS 9-42 or just switch to Ernieball 9-42. I wanna use GHS Boomers again because there almost impossible to break but I don't want to get my guita messed up again.
