I have used Ernie Ball strings almost exclusively for over 30yrs now. This is a slightly heavier gauge than I usually use,and they're excellent for playing heavy rock, metal or even the odd bit of punk. They stay in tune well, and last for ages. I deducted one star because the A string snapped when i was fitting it. I can only assume that for the first time ever, I got a duff string. Certainly something i've never experienced before from Ernie Ball. I will certainly carry on using Ernie Ball strings, as no other string , in my opinion, comes close.
