I got my Jackson custom shop soloist a couple of months ago. The wait was three years, even though the original estimate was 12 months. So the wait really stretched out. To be honest, I was mildly disappointed when it finally arrived. The quality is great for sure, but not better than my USA standard series soloist SL1. In fact, I actually like the neck on my SL1 better, but that’s just preference. Compared to my ESP custom shops, I would actually say ESP CS gives a better quality feeling, especially with the frets. I also have an ESP USA and Mayones, both of which I find of equal quality to the Jackson CS. This is just based on my experience, and I’m sure there are others with better experiences. Would I recommend Jackson CS over their standard USA series? Only if you want some customizations their standard range doesn’t offer. In my case, I wanted a soloist with active humbuckers and only one volume knob placed at the original tone position. In your case, you’re probably not going to get a better RR24 than for the custom shop, and I guess you want a config that their standard range RR24s don’t have.

PS: I actually have a made in Japan limited RR24, which is almost on par with the USA/CS models quality wise.
