Wondering if anyone has any tips my G5420LH just won't stay in tune. I bought the guitar in February 2016 but has been mainly kept in storage and only been taken out a few times until I started using it again this year. I've tried new strings to no avail, The G string is the worst going flat after one minute of playing. I did have to reattach the metal part of the bridge that sits on the top of the wood and pins and just left it as is with no adjustment. The cog closest to the E string is around 0.4cm above the wood while the cog closest the high E string is about 0.3cm above the wood. Could this be the source of the problem and it just needs readjusting? Any help or suggestions would be much appreciated. Sorry if the is newbie question, I'm new here.
