When looking for some new bridgepins I thought I better check back through previous orders to make sure I didn't buy the same awful ones again. At first I thought I had bought some cheap chinese ones off amazon,but I discovered I had bought these planet waves ones from thomann. They didn't fit without filing /sanding , none of the grooves for the strings (despite variations) went far enough to allow the pin to sit right down (you could manage on the thinner strings but not on the E or A). Very poor.
