piacere di conoscerti e benvenuto nel mondo di Sadowsky!
Lets keep this "international" :-)
The bass is indeed gorgeous!
Roger has used Bartolinis and EMGs in the beginnings, but than moved to DiMarzio for his Humcan J pups, both 4 and 5 strings!
Nowadays Roger uses Nordstrand too… I know the DM HC have gone through some tweaks through the years, but I'm not sure of the timeline.
I would contact Roger directly and see what he has to say about it!
Strings also matter a lot, on my Sadowsky I use SS blacks (I've experimented with several different strings, but TO ME the blacks are IT)
(BTW, your english is good)
