Tube or solid state?

Actually Gray, I don't think a pot is either one........

OK, to answer your questions:

The amp is solid state.

- and -

It hisses continously, but more pops and crackles as I turn it (this is only in the right channel), and at different positions, it hisses at different volumes, for example at vol. 2 it is exceptionally loud, but not so loud at vol.6.

I shall look into grease then, is this the grease that is a yellow colour (I have never head of the reccomended one), or do I need "special" grease?

I had a Telecaster Elite at one time that was noisy as hell. Replaced one of the transistors in the onboard electronics and cured the problem.
If the amp were tubed, I'd say it was a no-brainer...look for the 12AX7 in the front end and replace it. Solid state...I'd still consider the possibility of a noisy transistor or a bad solder joint.

I really don't think the problem is the pot. You could have a noisy transistor or something oscillating (another fault condition) Putting grease in the pot will not fix your problem and will ruin the pot. Take it to someone who can fix it or throw it out. Good luck.

Now i've heard it all, KY dries pretty stiff in a reasonably short period (a few days perhaps) of exposure to air.

Grease is the word.

Mr. Freak it's only a joke, son. Do we have to put a emoticon after each funny, so everyone "gets it", I hope not as that would be pretty pathetic.

trouble is, some people may not realise its a joke and just do it anyway.
