I think there are a few "gritty, held" RTs that you might like. Also Rhythm PopCountryBrent Ev 120 (baritone)
Re the single note parts, I would advise you filter by "baritone, electric," and check out some of the RTs... There are some really great ones with chords interspersed w/ single note lines that you may be able to chop up in your DAW to achieve what you're looking for.
As has already be mentioned, it's probably best to select direct input and use VSTs/plugins for drive, color, ambiance, etc.
