2 Pack Tuning Fork - Buytra Standard A 440Hz Tuning Fork, Musical Instruments Violin Guitar Tuner Device (Silver - 2 Pack)

This is exactly what it says, two A 440hz tuning forks. They work as intended

I use these for ear training in my music theory course. They’re pretty accurate and have helped me improve a bunch. Worth it for the price

Both were flat & required a couple minutes work on the grinder. One was just a tiny bit flat, the other was quite a bit. Just touch them up, ,take off a little length on the grinder, a file, or using a dremel tool with a grinding wheel, testing as you go, until they're a true 440 Hz A note.Nice inexpensive tuning forks. A great tuner that doesn't take batteries.Photos are before grinding, then after grinding.

I bought a bundle of these for my a capella students. It does exactly what they are meant to do. The kids love them. Only downside is, the finish on it leaves a sticky residue. But when you're working with children, does it really matter?

Fantastic tuning fork - I use it in the music classroom and it does a fantastic job.

Poor quality control...Of the 4 total 440hz tuning forks I ordered, 3 were not at 440hz (all slightly under pitch). I checked them on my guitar using 2 different brands of clip-on tuners.BTW, if you don't feel like returning them, YOU CAN ADJUST THEIR PITCH UPWARD EASILY. It does require a metal file and/or fine grit sandpaper (I'd suggest 150-250 grit, and maybe some 500grit). Alternatively, you can use a Dremel tool or a grinding wheel to speed up this process. To RAISE the pitch (if your tuner is showing that it's too low), you simply sand down the tops of each side of the tuning fork tines. You want to sand each side the same number of strokes. Go about 5 strokes at a time (sandpaper), 1 stroke at a time with a metal file, or 2 quick buzzes on a Dremel, then check against a tuner. If it's still flat/below pitch, repeat the process SLOWLY and check repeatedly...keep doing it until it is reading at the correct pitch. Use the fine 500grit paper to polish up the edges without removing more material than you need.If the pitch is too high, this is more involved (you remove material at the "U" using a file). Do a Google search for "tunelab calibrating tuning forks" for more details on both raising and lowering pitch.

Only needed on in this range but got a two pack. It's a tuning fork and it works. seems well made

Not only did they both sound sharp, but two tuners confirmed they were both 12-13 cents out of tune. I would look elsewhere for more accurate tuning forks, it baffles me how anybody could have let these through quality control, they are just too noticably wrong.
