It's just quality all around, from the body to the brass shaft to the smooth operation.
I've bought many pots throughout the years and never had one give me that hummmm this is noice feeling like these ones did.
Makes me want to lose my mind and redo the electronics of all my guitars.
Hello bankruptcy my old friend....
And like the name says so, it has a long shaft, so before you measure, make sure your guitar can handle it.
