Well, all the pots were technically within tolerance, so I really can't complain--especially considering the value for the money. In fact, two of them exceeded 500K (525k and 526k) at full volume, so that's pretty awesome.Of the other two, one maxed out at 468k (totally acceptable) and the last one maxed out at 439k.Again, all are considered within tolerance, but I personally can't use the 439k pot. That's just enough to create an audible effect (albeit very minimal) on the tone, so I'll save that one for practice or demo videos.
