Need help finding a potentiometer

[hdracer]

I have been searching for a certain pot for a bass I am working on and not having any luck.
The pot is for a mid tone in a active bass. It looks like a normal 500k mini pot but it needs a center detent.
I am not sure what that style of pot is called so it makes it even harder to search.

its probably a 50K pot. If you don't have a MM post some pics

It's called "B500k with detent." (I'm assuming a B taper. Log tapers are uncommon with detents.)
Are you sure it is a 500k pot, however? That's rather uncommon for mid pots for preamps. Could be a 50k or 100k.

Could also be a 20K.

I read it wrong. It is a B50K
