I both agree and somewhat disagree with this, having swapped HC's for SC's in my old RV5 when I had it. Yes, it does 'darken' the sound in that there is less treble extension with the SC's which somewhat diminishes the slap tone on this alder/morado model. For me though, the SC's enhanced the inherent midrange of that bass and gave it a truly burpy sounding bridge pickup sound and overall a better lowmid kick when both pups were centered.
Of course, that whole pickup swap, as well as me eventually dumping that bass was only one more step towards 'the perfect Sadowsky' for my needs: The ash/maple PJ5!!!! Not that I still don't crave 7 or 8 more Sadowsky axes in various pups/woods/models. And now they have to offer a roasted neck option!!! I do have a 'dream' model that would just kill: ash body J5 with SC's, and an ALL-WENGE neck!
Flats would definitely change the entire dynamic of what I'm talking about. However, it sounds like we are hearing the same thing. I can see that the more compressed low end of the SC's on the RV with flatwounds might be a very good thing... controlling that deep fundamental of the flats a bit more. And, the upper treble and even lower treble impact would be minimal with flats compared to the stainless steel roundwounds I use. So +1.
