I replaced one of the volume pots on my DGT with an equivalent rated CTS pot as I was constantly adjusting the volume accidentally. Whilst the new put is nice and stiff, rolling back the volume sucks the tone (which the original pot didn't do) and also adjusting volume in the middle position is now a waste of time. Does anyone have any suggestions for a pot that has the qualities of the std DGT pot, but has a stiffer action?

What some players do is simply use a felt washer under the knob to offer a little more friction as the knob moves. Personally, I don't find it a problem, as I like things to go really easy, but everyone's different.
PRS pots are great, as you've seen, they work really well in all of their settings, while other pots tend to have different tapers, and send the highs to ground much too quickly.

This is the problem with the new pot, touch it and it's like I've set the tone to zero (perhaps a slight exaggeration). The other problem I have is that I can't try the felt trick as I nuked my PRS pot with too much heat!
Unless there is a very unusual resistive material, it isn't rolling off highs any differently than any other pot with the same value and taper. If you hear it as rolling off highs, it likely means that there is no "treble bleed" circuit installed on the new one but there was on the old one, or it means that the tapers between the two are really different and the new one rolls off too abruptly.
A 180 picofarad cap between wiper and output is a cheap and easy treble bleed circuit that you might try.
As for more friction, the main difference internally is what kind of grease is used: thicker grease on the lubricated surfaces (not the resistor element) makes the pot stickier. Oil or no grease there makes it move without effort, which players who do volume swells with their pinky like.
HTH,
Custom tapers are commonplace, which can result in a variance in response over the length of the wiper. To my knowledge, PRS has not claimed that he DGT pots were any different than other models' pots, but it is possible to get one out of spec. But Greiswig is right and chances are good that the difference is due to the bleed circuit and the specific pot wiring.

Yippy ki yay...
You likely installed an audio taper pot. Replace it with a linear taper and see what happens....
Thanks for the replies folks, I can't trace the CTS part number "1048" is the only visible identifier (other than the manufacturer and rating) ... given there's a cap on the pot, the audio taper pot would seem the most likely explanation.
