Problem with neck
​
Hi so I bought a Squier CV 60s jazzmaster secondhand but it came with some issues i only noticed after some time and it's really frustrating and because of that i don't even play. First is some electronics problem that the bridge position sometimes doesn't work i had the switch and cable changed in my local music store but that didn't help and i also had the trust rod adjusted like 2 times but it is again bad and I get really bad fret buzz on 12th fret and around on low e it's most hearable i have one last option to get it to someone i heard is really good that should help me but it's in other town so it isn't that easy yo get it there so i just wanted to know if i should be positive that the guitar will be good or just be mad at myself for making that purchase
