Perfect every time

The usual high quality you expect from Schaller. Ideal if you use straps across multiple guitars, saves buying a whole set each time.

Top!

I bought a set to install in my Jackson guitar since I'm using Schaller strap buttons for many years. The pins fit perfectly in my strap buttons and lock securely. The quality from the screw to the pin is excellent.

Bit expensive, but really good quality
Blakers 24.01.2026
I found these to be a bit expensive, but buy them every time as they are really well built and, in combination with the strap locks, are completely wobble free. Also the click in and release mechanisms are super smooth.

I like that these can be initally screwed in by hand, and use a more robust hex screw to install (which is nicely recessed into the pin). But this could also be a downside as you can't use the original screws, which is what I have done in the past with other strap pins.

Also note that the screw is quite long. This hasn't posed a problem for me yet, but there might be some guitars that would need the hole drilling out slightly to avoid any wood splitting.

Great but overpriced
Popes666 28.06.2026
These work great as intended but I feel they’re a tad too pricey for what you get. Put these on a Strandberg and it sure does poke you pretty good in different angles.
