Hi everyone!! I have a Broderick signature 7 string guitar, and the B string buzz when played open and other frets... String action is about 2.1mm on the last fret, and there's a lot of neck relief on it. String gauge is 59, but i try it on 68 and it's also buzzing... Please HELP!!!!!!

if you ask me, it's probably just your neck that ''moved'' due to a change in temperature. if so, you need to adjust the rod.

You say it buzzes on open, and all frets..???

If it were all strings doing the same the same thing, I would say it was neck bow,
but since it's just the top string I would check the following

- Make sure the pickup is not adjusted up to high.
- Raise the action just a tad on the top.
- Check the saddle position, make sure its not damaged,
- Also I have seen a "KINKED" string fret out on the pickup, or 24Th fret area.

As stated by ao_samurai it wouldnt hurt to check the neck bow,
Hold the string at the 1st, and 20th fret, check that you have 1mm gap at the 12th fret area. more or less, some guitars have better results with different gaps
the frets used to guage will vary also, depending on whare the nech meets the body.
