Hi peeps. Just got myself a tanglewood semi acoustic. Im a total beginner so i took my friend to the shop to buy it and it sounded awesome. I was given some new strings with it and after fitting them the guitar really sounds awful now. nothing like the same tone and clarity, and some buzz. It looks lke the action shifted to be honest. Is this normal. Is it to do with a different gauge strings. Please help me to get my guitar sounding gorgeos again. Thanks in advance
