If you have any affection at all for the tone you got with the Modulus you have on the block right now, there is no doubt you may be VERY smitten with my Modern.
Mine is actually a mahogany core, which is alledged to be even a bit darker and smoother than Alder. It seems to make sense to me, as my modern, while absolutely "modern," is not particularly bright (unless you want it to be) and very smooth and buttery in tone. It's very clear and articulate, but not really what I would call aggressive. There may be something to the Modern w/ mahogany thought. When my son and I did the "study" most all of the 'hog core bodies were on the moderns.
Actually, the tone has a bit of the same vibe as the "original" Q5 I had, which universally was viewed by those who know Qs to be a bit warmer and "organic" sounding than many. The Sadowsky has even a touch more of that more "natural" midrange texture, but in many ways remarkably similar. It doesn't have as much of that "bell tone, piano" sound as does a Q5, which I actually like. It sounds more like a bass guitar. But, the notes are probably as "quick".
And lastly, a gratuitous pick to promote GAS pains:
