Just got brand new bullet mustang.After I tuned the string with fender tuner app,all strings are great except the 6th string(low E,thickest string).Though the app says it's tuned it’s loose and you can hear fret buzz and bridge buzz.But if you tighten the string all the looseness,the buzzing goes away but the string is not tuned to E coz it’s tuned up.how can resolve this issue?

    It is possible they may have placed an incorrect string, maybe an A where the E is supposed to be. Does the E string look noticeably thicker than the A string? It should. Nov 13, 2020 at 3:13
  • Either find someone who does know how to tune properly, or go straight back to where the guitar was bought.

  • It's just possible you tuned it to an E one octave too low. As you tighten it, check its tension by hand as you get it tighter. When it feels similar to the other low strings, does the note approach E?

If it's playing the E that it says it is, and the A on the fifth fret is the same A as the open A, it's in tune.

If it's too floppy for you, and you can hear string buzz, then you can either adjust the truss rod to get more relief in the neck, raise the saddle a bit, or go for a thicker low E, which will mean you get higher tension for the same note.

    Why would anyone (especially someone who's a newbie) be adjusting trussrods etc on a brand new guitar? It's back to the shop before something really goes wrong!

A Mustang is a short scale instrument.
Thicker strings would always be good, as you need less tension on a short scale to achieve the same pitch, compared to a long scale.

Personally, I use Ernie Ball 'Skinny Top, Heavy Bottom', 10 - 52, which keeps the top end reasonably light & the bottom 'firmer' than regular 10s.


You sure you got all strings on and functional, cause ringing, buzzing, and dead frets equate to truss rod adjustment. I'm not telling you to start cranking on your truss rod, just sight down the neck by holding the back of the guitar up to eye level. What you looking for is any mis-shape to the gradual curve of the neck, a weird warp, and you can actually see the frets to, with no strings on it. Sounds to me that you need a professional setup done to the guitar, or you maybe screwed with a warped neck and looking to replace the guitar. Take your guitar into a local music store, ask the tech, "How much for a professional setup?" If it's anywhere between 30-50 dollars it's worth having it done cause 10 of those dollars is a new set of strings. If he looks at it and finds a critical issue like warped neck, he would be the one to tell you so, before you spend any money. Good luck!!
