I have to give Musiclily a lot of credit on this one. I ordered the 52mm when what I actually needed was the 50mm, which was my mistake. I let them know and they told me they were out of stock of the 50mm but would send me a set when they were back in stock. It was about a month later when they arrived, and they're still not an exact fit, but much better than the 52mm. That's five-star service in my opinion, though the pole piece for the low E-string doesn't quite line up with the hole in the cover, so I took one star off. Still, I won't forget their good service and I'll buy again from them in the future. Both sizes were very shiny and reflective, and the 50mm will suit the Squier Strat I'm working on just fine.
