Maybe they do consider it normal for their pots to have some play. Myself, I don’t.
Decide what pot you’d prefer. Might be a good idea to avoid the “what is easiest on the wallet” approach. CTS and Bourns are both nice options, for example. Pretty sure you can find that for around $5 a pop.
Replace them.
Maybe don’t sweat the place you bought it. I keep a wad of Bourns pots on hand and I totally expect to swap out the pots on most Guitars when I first get them.
