Sr. Martins -> Back Buzz (Mar. 14 2013 9:53:14)

Is this time of the year prone to backbuzz? Iam having around 60 to 70% relative humidity and a backbuzz on the 6th string at many frets.

Help?

That only makes the guitar more flamenco. [;)]

If you have back problems, use a heating pad.

Like fret buzz?? Humidity does swell wood so your fingerboard can swell a little, it can even push frets up.



Ricardo -> RE: Back Buzz (Mar. 14 2013 15:35:39)

Put a shim under the bass side of the nut. Often just paper or business card slivers is plenty to kill that buzz.

That's a good idea.

I have it shimmed right now and the back buzz only goes away if I remove the shim.. but then I get open string buzz.

Iam on the middle of the road now using the shim... just a bit of open string buzz and a bit of back buzz.



By the way, the only buzz happening on my back sounds more like machine gun picados and golpes.

To be clear...you shimming the NUT not the BONE saddle correct? Maybe i don't know the sound of "back buzz"



Sr. Martins -> RE: Back Buzz (Mar. 14 2013 16:54:54)

Yes, the nut.

By back buzz I mean a "zing", a sympathetic vibration between the nut and the fretted note.

Yeah it's what I thought, so shim up the nut higher, I promise it goes away. Action is only affected at fret 1.



Sr. Martins -> RE: Back Buzz (Mar. 14 2013 19:26:50)

Well.. I had to sand the shim a bit on the bass side because I found that the higher it is the more "zing" I get. To make it even higher to avoid contact with frets (zing), that would be a bit to high...

Maybe its the string or the humidity... the fingerboard is already 'sticking out of the frets'. It has been raining everyday and the humidity as been always around 70% and sometimes more.

I'll see if it goes away with the weather/string changes. My only concern is if it was something structural that wouldnt go away but I cant see anything besides the swoolen wood.

Pencil lead helps with nuts that grab the strings and make tuning difficult.

I'll just let it sit as it is and see what happens. The guitar is new and this harp-like-'zing' as only appeared a few days ago.

Sounds like a bonus harmonic! [:D]



n85ae -> RE: Back Buzz (Mar. 15 2013 2:24:34)

I've had a couple guitars over the years with some weird buzzes, and here's
how I solved them.

You can make a little electric circuit with a battery, a flash light bulb and a couple
wires, hook a wire to the string in question (only works on bass strings) , and touch
the other wire to the frets one by one until you get the light flickering at the
moment of the buzz/ring.

Having some alligator clips, and a second person to help will help. You might be
able to do the same thing with an multimeter using the ohms setting, maybe on
the k-ohms, or megohms range setting would work best to catch that it's
contacting.

This assumes you know some basic electricity, and assuming it's a fret buzz.

I had a guitar with a buzz, and it was actually a loose strip of wood (don't know
the name of the piece) inside the lower bout where it sits on your leg. Reglued it
and it fixed the problem. So look or feel inside for loose wood. That can be a hard
one to find if you're hung up on it being fretboard/string related and don't look inside.

Regards,
Jeff



estebanana -> RE: Back Buzz (Mar. 15 2013 4:27:09)

Could also be a loose fret end.

Go down the whole finger board with your thumb nail or a small block of wood and press down on the top of each fret at the edge of the fingeboard. You may find one that wobbles up and down.

If you do, put drop of crazy glue next to it and let it soak in next to the fret. Quickly wipe the excess glue with a paper towel and then push the fret in with the block of wood and hold it for a full minute.

A loose fret end can bounce up and down, but the guitar can look perfect until you press it in and feel it give.

So are you saying that we should think inside the box?



Sr. Martins -> RE: Back Buzz (Mar. 15 2013 8:03:08)

Some nice suggestions there. Never thought about that eletrical solution. I might try that with the multimeter and a capo acting as a second person. It is surely a case of back buzz and its just on the 6th string. Yesterday it had almost no zing so it must be the climate.

I'll keep checking on this. Thanks.



Sr. Martins -> RE: Back Buzz (Mar. 15 2013 12:48:05)

Seems like the buzz got scared of you guys. Completely gone today [:)]


There's one last thing I would like to know in order to be even happier with my guitar.

What should I use to polish ebony in order to get that smooth almost glassy look? Steel wool?

I have noticed half millimeter action decrease at 12th fret due to humidity on my flamenco and steelstring guitars and it sucks



Sr. Martins -> RE: Back Buzz (Mar. 15 2013 12:55:30)

That would be a case of "front buzz" [8D]



n85ae -> RE: Back Buzz (Mar. 15 2013 20:22:33)

I always do that, much to my wife's dismay (yeah bad joke, right).

Jeff
