Yo Johnny Two Tone
How did those pots change/improve your tone/options?
How are you finding the new pups? (in terms of brightness, clarity, tone, etc)
The pots are great. The RS Guitarworks Audio Super-Pot is an absolute must in my opinion. It turns the volume down so gradually and evenly that you can play your guitar at any volume and have it still sound great. You have to get a .001uf treble bleed cap to slap on it though so that you don't lose the treble when you turn the volume down (you can just reuse the one on the old pot).
With the tone pot, though, I recommend getting a top quality "linear" pot rather than an "audio" pot like I got. Audio pots have a more dynamic taper that is meant for volume control because our ears don't pick up volume changes in a linear pattern, but with tone you want it to change gradually on an even slop - not dynamically - so a "linear" pot is much better. So, get a high quality linear pot for the tone.
As for the Hovland Musicap (which you slap on the tone pot) they are sweet. Capacitors aren't going to change your sound too much just from brand to brand - it's all about their rating and how accurate it is. The Hovland .22 cap helped smooth out the sound of my humbuckers and I definitely recommend it.
On to the PUs. The DiMarzio X2N is infamous for its ultra heavy sound. This PU is the hottest passive PU out there and is so heavy it's crazy. Hugely recommended for bone crushing metal tones. It sounds really good in my RGA. I wouldn't recommend it if you aren't a metal player, though. It's really good at clean sounds to which is surprising. The DiMarzio "The Breed" neck PU is a great match for the X2N. It's a tight modern tone so done expect vintage neck tones.
EDIT: Oh, one thing to be aware of is that the any pots that are made in America (like RS Guitarworks stuff) are a little bigger than the holes on these Japanese made RGAs, so you will have to take some kind of tool to open the holes up slightly. I took two drill bits (DO NOT USE A DRILL) that were one size bigger than the hole and the next size bigger than the hole (equaling the size of the American pot). BY HAND, I twisted the smaller bit through the hole (it shaves off a tiny bit of wood) than by hand twisted the next bit through - voila!
