Is it normal to have a little fretbuzz?

Its not normal, especially near the nut. Não é normal, ainda mais nos primeiros trastes. Esse Luthier é fraco.

If it's near the nut, the problem maybe relief/trussrod, or a poorly cut nut. Se o problema é nos primeiros trastes, dever ser tensor ou o nut está mal ajustado. Bring the saddles down and work with the trussrod and nut. Abaixa os carrinhos e ajusta o tensor e o nut. Se não resolver, precisa alinhar os trastes. If it doesn't work, you need to level the frets. E foge desse luthier/run from this luthier.

For what it's worth, I have always pretty much set my relief and string height to Fender specs and been happy with the results. I've been doing it so long that I set them up without any measurement tools and if I go in to see where I'm at it's pretty spot on to the factory spec. No discernible fret buzz but probably just the way I play. Someone else might make them rattle a bit.

 

Step up. Buy a pre-2000 American made strat. Like a signature Clapton or Beck and you won't even know what fret buzz is. By the way, what is fret buzz?

 

+1 my mij strat had some buzz when I got it. With a normal set up it went away.
To me normal is set relief, intonation and action.

 

I'm not really hearing any noticeable buzz in your test.

 

I hear it on the lower scales you're playing. I don't hear it higher up or on the chords (but you might playing live). I think that tells us you have a relief, neck angle, or fret level issue and most likely a combination of at least two.

Try this: Play those low fret number scales. Figure out where the strings are hitting the other frets. Give us some more information on that - where you are playing when it's the worst and where it is hitting. Then play up the neck and fins any additional buzz. Report back.

If you can't figure it out, try playing notes up a single string, one fret at a time, figuring out at which position it buzzes and which ones it buzzes on. IN other words "I play the G string at the 3rd fret and it buzzes off the 15th fret". You can also try sliding a single sheet of paper under the string(s) from the bridge end down as you hold down the frets from 22/21 down to the 1st on each strings. See if you can find some high frets.

We need more data.

 

It sounds like you're picking the strings on the hard side in that recording. If I'm right, that may be contributing to a small problem, making it bigger.

 

From that test. It does not sound like you have a problem to me. Mine has some buzz, but I don’t here it from the amp. The older the strings get the better it sounds and plays.

 

Sounds great to me. As @Triple Jim says, you're playing with quite a lot of attack, but even so the buzz is barely discernable.

 

No disrespect meant for anyone but I setup my own guitars and my necks are flat straight and I do not have fret buzz. I also like the action as low as possible. Normally much lower than Fender factory specifications. That being said, every guitar varies, so it may not apply to every single guitar. It really depends if you can hear it when playing and how much you are bothered by it.

 

Picking a little harder, or more aggressively, than average. Sorry for the use of the idiom.

 

I heard a little plinky sound on your G string. You might want to raise the action on the G. Also, if your frets were leveled try a shim in the neck pocket. I just did that with my granddaughters mini. I just used a piece of a business card and set it right before the lower end of the pocket, just where it almost touches the lower screws in the pocket. Changed everything completely. Now it plays pretty slick.

 

Your 15min is used up. See ya next time.

 

It sounds to me like you hit the strings pretty hard. I heard a couple wonky frets. I would suggest you raise your action a little. Do you know what it's set to?

A setup is not a one-size fits all. It's all about technique. A low action and little relief is fine if you have a light touch. But if you dig in and hit hard you need higher action.

I'm not saying it's a bad thing to hit hard. Yiu might just need to go a bit higher.
