Actually the starting point of a shelving bass control (or even the center point of a very wide Q bass control) has very little if anything to do with how the deepest frequencies are impacted. It all has to do with the slope and/or hi pass cut off way down deep.
I love the Sadowsky pre with J Basses myself. However, there is a LOT of boost in the boost only bass and treble. The usable range of both of those controls with most rigs (i.e., rigs that are even and fully voiced from top to bottom) is between 'off and 25%'. The Sadowsky pre with just a touch of bass boost applied is just fat as anything. I love it.
I have not had the pleasure of trying the Nordstrand pre, but all indications are that it is a bit more subtle than the Sadowsky... maybe a bit closer to the amazing Alleva-Coppolo preamp, which has similar bass and treble boost frequencies as the Sadowsky, but is much more subtle, and usable throughout the entire range of the boost IMO and IME.
