I really like my new S6. It came with 12 gauge PB Cleartones which I really liked. Yesterday, I replaced them because one of them broke, after 3 months. Since then I'm having really bad intonation on my G string, only at the 1st fret. Can it be because of the new strings? Both are 12 gauge sets (new set is ernie ball earthwood's, medium light, PB); HOWEVER the new G string gauge is 24 while the cleartone G string (now broken) was 25. Could that be the reason? I find it hard to believe that I didn't notice this sharp note for 3 months. I failed to find a 25 G string, and the Cleartones are not availble in my country. Any ideas / suggestions? I'm quite worried. Thanks!
