2 Pcs Tuning Fork Set Key of A 440Hz / C 523Hz Tuning Fork for Violin Guitar Piano Tuner Musical Instruments Device

The C fork is playing C# and the A fork has rust on it. Pretty disappointing for a brand new product.

A is close, probably about 442Hz, but the C is closer to a C# than it is a C. Maybe about a C# where A=438. Don't buy this for the C, and go buy your A fork somewhere else

The "C" tuning fork is actually a C# which is very unhelpful.

Should have read reviews. "A" labeled one is very close, a few hertz sharp, "C" labeled one is between "A" and "A#", probably around 450hz. Bought it for the "C", too. Sad. Grinding sounds easier than returning the product, so I'll get my "C", but I wasn't wanting to buy a project.

They say different Hz on the fork but sound identical. So not A and C, but two A forks.

I just received these tuning forks. The A was a quarter tone sharp and the C was fully a C sharp. Quality control is clearly nonexistent

Came sealed but the A tuning fork came with a little rust

The fork marked C523 is an “A” as other reviews have noted.
