A250k Electric Guitar Potentiometer Volume Tone Pots Long Split Shaft 18mm Pack of 5pcs

They work great. Good action, not cheaply made.

Those pots are low quality, but fully functional with an acceptable audio taper. They fit metric pickguard holes w/o any reaming and solder fairly easily. However, their turning torque is extremely high. So if you're afraid to accidentally change your settings while you're playing, these are for you. If you use your pots a lot (like me) these are basically useless.

I used 2 of these in my Yamaha Electric Bass Guitar and they worked great.
