This strap lock works perfectly well with my Fender Stratocaster. However, it is very difficult to fit to a Gibson and almost impossible in the case of my acoustic Fender. The issue is that the strap pins are not all of the same length and, sometimes, they are actually too short for this strap lock. When it fits, it is great. But when it does not fit well, it might be really difficult to properly close it around the strap pin and it might be very difficult as well to remove it.
