I have several CS Charvels, they are some of my absolute favorite guitars in my collection. I have yet to get one that wasn't a very nice player or was dull sounding, the necks feel fantastic. Only one has had a notable quality issue, the trem cavity wasn't routed exactly right and was interfering with the Floyd's performance (sticking a bit). Fortunately my tech was able to do a little bit of extra routing (inconspicuous, still hidden under the Floyd) and it turned out fine.
All were existing guitars purchased through dealers, not through me placing custom orders. I've tried to get a quote on a custom, and similar to what was said above, wasn't happening, actually never heard back.
