So I got the Electromatic G5420T last week, great guitar, loving it and boom... Everything keeps going out of tune, once tuned won't stay there for longer than 5 minutes. Then annoying harmonics start coming out of the bridge which the amp picks up... The shop says it shouldn't be happening and they will take a look at it, got a phone call nothing can be done... only thing to do is lubricate the nut and the saddle and that will minimise the issues then, tie something around the strings past the bridge to get rid of the noise. Any thoughts on this? I'm very 50/50 about it, the shop is offering a refund or a free setup and I'm just gonna have to learn to put up with those issues and try to minimise them.
