Dead Note

[viking]

I have a problem and I don't know what it is caused by. When I fret the b string on my guitar at the 7th fret it is muted by the next fret i don't know if it's fret wear or the nut or the bridge the nut is in good condition so is the bridge and the frets look good the truss rod I adjusted it was way off but fine now the action was high but I fixed that too it's just a beater guitar I got for real cheap so.

sounds like not enough neck relief

Longest sentence I've ever read.

If it only happens on 1 string then the frets are not level. Sounds like you got a low spot.

that might be right on thank you

Or the next fret is a hair too high. Since it's a fretted note you can rule out the nut as the cause, and the bridge is unlikely since it affects only one fret. Use a short straight egde to assess whether it's a low 7th fret, or a high 8th and do a spot leveling if it's a high fret. If it's a low fret you'll either need to level all the frets, or replace the low one and dress it to the same height as the rest,

yeah I was thinking of that too. How do I use the straight edge? same way as I would to check neck relief?

[Setch]

You'll need a very short level, and you place it over 3 frets at a time. By rocking the level over 3 frets at a time, you can work out if the middle fret of each set of 3 is high, low, or level compared to the rest, and thus deduce which is the bad fret.

Stew Mac sell a tool for this, but I'd just make one from an offcut of hardwood or plastic.
