Re: rg prestige 2550z doesn't stay in tune
First of all I would like to thank all of you for your answers. The strings are stretched in and the stud locks are installed. The guitar isn't brand new, I have it for about a year (so the factory setup was somewhat redone by me and also the strings changed a few times and the locking nut was always locked properly).
I guess the guitar always did that, but hadn't really noticed it (the difference is somewhere between 30-50 max) because all the strings get sharper or flatter, so the difference between strings was negligible for my ear. Only when I tried to play with a record, I noticed they were a little flat.
I will try the lip balm thing as I understand it works wonders. I don't understand the last bit: "These locking studs have a U-shape pivot and provide a better return so do replace any V-studs! Be sure it also has anchors that have a metal base to them else it won't work!".
Could you please explain again?
