New Majesty issues – help!

I bought a brand new Music Man Majesty 6 at the end of September in Starry Night finish.

I’m asking for your help because the guitar has a ton of teething problems and I’m not really sure what to do.

Firstly, I had to adjust the bridge because it started to sag into the recess. I managed to correct that problem myself even thought I’m not particularly proficient with tech stuff.

The B string just will not stay in tune. I have lubricated the nut, bridge and changed the string multiple times as well as stretched it out and tried to play it in. Nope, just slips out of tune.

I have broken 3 top E strings since I bought it (so roughly one a week) whilst only playing it for no more than an hour a day (often less). They all break in exactly the same way – the string ‘pops’ and looses it tension. I tune it back up, start playing again and same thing happens. After the third of fourth time, then string stops tuning up and it snaps at the ball.

I’ve also had an issue a couple of times where the pickup selector stops working. I have to unplug the lead and then plug it back in and starts working again.

I’m reluctant to take it back to the shop as they don’t know much about music man guitars and it was really just somewhere I ordered it to.

It’s a shame because the guitar is great.

Any help would be most appreciated.

Thanks.
