do 500k/500k or 1M/1M concentric linear taper pots exist?...

[hachikid]

cause I can't seem to find them. does anyone know where they're being sold, if you do?

Here's one - there are others at mouser as well.

Form factor might be, ah, challenging...  Depends on your skill at adapting things for your use and all that.

Update:  Here's another from Small Bear.  Slightly less 'challenging'

hmm. would those prongs be any sort of a challenge when trying to get the wires, or anything else, on there when soldering? or am I just going to probably have to deal with an audio taper?

Well, it's designed to be mounted on a PCB.  If this were me, I'd mount it on some perf board and then solder the wires to that.

and then solder the wires to the perfboard?...I've never worked with that before.

You can use a type of perf board called 'tri-pad", (as in comprised of a series interconnected three pad groups:

Cut it down to whatever size is convenient, position the pot over an unplated strip with the contacts on either side, and you then have open pads connected to the pot to solder your connections to.
