Logo wise there are a few changes they implemented as the ranges diversified.
Sadowsky + NYC/Guitars NYC for American
Sadowsky + Guitars/Metro/Metroline/Metro Express for Japanese ones - early ones don’t have the VTC preamp.
Sadowsky + TYO/Tokyo - Doemstic Japanese models.
then we’ll start to see Metroline German and Metro Express Chinese...
All very confusing.
Sadowsky Metro/Japan are deemed to be very similar, NYC models benefited from weight relief from mid 2000’s but the electronics etc were the same - NYC was basically custom shop, Japan like a “standard” line.
I own a Metroline HPJ and have owned an RV4 Metroline - I’ve played a couple of NYC’s. Quality is the same - and both of my Japanese ones are/were fairly light anyhow.
The later 2015/6 to 2019 seem to be the closest to NYC - but they’re wonderfully made instruments.
in short -
NYC - limitless custom options and weight relief.
Metro/Japan - standardised features, no custom options.
