Ok, good stuff.
I'll clarify a bit: :)
60's pop/rock and jangly seems about right. It's that sound that's a little hollow in the mids and a touch bright, I would say.
But I don't want to overemphasize this...I just wish the Mira had "hints" of that sound in it. So far there's basically none, whereas for example my McCarty can do it a little - that would be enough for me.
Obviously, the Mira wasn't designed to be jangly, but IMO with different pickups it should be able to do it at least a little bit.
The switching will include two mini toggles for outside coil / HB / inside coil switching of the 2 PUs and the 5 way will then choose Neck / Both / Bridge / Series / Series OOP.
The idea is, to get the best of the older and newer PRS rotary-style settings in a managable package.
So, yes, split tones are important, but not necessarily in the form of "a single HB-coil on its own" - I find those sounds rather anemic, too, usually.
I've thought about VHIIs but read on severaly threads here, that they don't work well in SG-type guitars (consensus seems to be either vintage or high-output for those guitars) - but I guess I can very easily convinced otherwise... :D
Concerning RiffRaffs, yeah, I need some convincing, but that's why I asked in the first place, right?
Stormy Mondays don't seem to be the ticket, according to the replies so far...
