To put it simply, his is the best potentiometer you can get.
1) It's very slinky, you don't need to use any force to turn it, which is very nice when you want to adjust your volume or tone while playing. CTS pots which have a good reputation are much stiffer and cost more.
2) These are very cheap and you have both 250k and 500k, as well as audio and linear taper pots, so there are many options to choose from.
If you want exellent pots for your guitar, please, look no further. These are so underrated and SO GOOD!
