I'm looking for what Bournes refers to as B1 taper:
So far all I could find is the PTL Series slide pots with LED at Mouser:

At $10.57 each, or $7.41 for 10, not exactly on the cheap end.
I bought a bunch of Behringer B10K slide pots from AliExpress back in August, and I just find out now in testing that they're not exactly linear. They have a slight curve to their progression; moving 1K for the first and last 1/4 of travel, and 8K within the middle 2/4s.
I had tested the center at 5K, but that only eliminates the A and C tapers. You really need to test at 1/4 and 1/2 of travel for 25% and 50% of Ohm rating (just looking for taper B is not enough). The ones I got seem to be between the B3 and B4 curve.
I'm also trying to find caps with 6mm x 2mm holes for these pots. I can't find any. I'm starting to think that audio companies use custom caps, or they don't even cover these at all.
I thought they'd use a cap with a clear/semi-transparent center cause these slide pots don't have dust covers like the Behringers.
