So I accidentally knocked my guitar from the stand and I have tile flooring so it went face down smack down on to the tile floor and now when I tune it shows in tune on the tuner but you play a G chord it sounds completely whack.
I checked the intonation so that's fine but i'm thinking maybe it could be the truss rod? if so what would be a good way to adjust it and be able to know i'm doing it properly? The guitar is an epiphone les paul custom but with a bolt on neck.
Help would be kindly appreciated
