Not sure if I can make this a sticky or pin this to the thread….
But it was asked on the Sadowsky Bass Facebook page a few days ago the differences in all the variations of Sadowsky basses over the years, and this was my basic synopsis (minus the MetroExpress):
TYO (or TOKOYO) line made in (assembled actually) Japan from NYC parts. But the preamp had boost/cut on treble, boost only on bass.
Metro line originally made in Japan from Japan sourced parts with NYC preamp. Now made in Germany with German sourced parts. Roger Sadowsky has said many times, if you want a Sadowsky, but do not want a custom built instrument, get a Metro.
NYC is completely hand made in NYC, directly overseen by Roger himself.
