I have done the RS upgrade several times and for these reasons. The stock CTS pots that came in my LS150 (although great) had an average value of 430k not quite the 500k as most would think they'd have and is generally the case with most pots now days in most off the shelf guitars. The RS Guitarworks (CTS) pots are hand picked as well as have a special taper for the volume controls and have averaged 540k with every set I've bought from them, thus averaging 100k or better than stock CTS pots, this translates into more sweep, as well as more resistance, which has an affect not only on volume control and feel but tone as well, and IMO for the better. As you can see from the photo above, I have done more than just change pots, the wiring is now all vintage braided (50's circuit), the ground buss is solid wire and the tone caps are vintage black beauties, the same tone caps as Bumble Bees, just a different color jacket. Making a noticeable difference with guitar tone is generally a collective work IMO. May sound crazy but the nostalgia seems to add to the overall MOJO and helps me play better as well.
