It feels like I have to get my BT tele set up every couple of months to keep the neck/intonation in line. Is this just a normal side-effect of MIM guitars, or am I doing something wrong? It seems like even just changing the strings throws it off. SO, that being said - I have an opportunity to possibly buy a USA G&L Comanche used from a friend. I've played it before through my setup and liked it a lot. My question is, will I see a dramatic improvement in reliability? What makes a guitar have solid intonation? Thanks guys.
