These tuners are new in my opinion. I saw them first on the American Performer Telecaster. They are new because there are no screws in between the tuners, like the other Fender or perhaps Kluson Vintage tuners.
Most American and Mexican made Necks will have 2 smaller holes next to the main peg hole and the 2 positioning pins fit those perfectly. So, it is easy to change out your standard tuners for these.
I replaced staggered tuners (Low E and E stems were longer) with these and I had no tuning problems.
My advice: do a bit of homework to see if your neck is ready for these. If it is, the change takes just a few minutes.
The price Thomann charges is a fair price in my opinion, and they of course arrived quickly. So, well pleased with my purchase.
