How to spot a first or second batch bass? Is there a way to find out, let's say, by serial number?
If you can actually see the bass in person, it will say when it was made. Mine was made in 2021, so it was probably in the second or third batch of RSD’s. I am very happy with the tone, fit, and finish of my RSD. The pickups are noisy soloed, but turning down the amp’s treble makes the hum very manageable. Whenever the drop in preamps and noiseless pickups become more readily available, I will be very tempted to get a fretted MetroExpress Sadowsky and and the upgraded preamp and pickups. I am certain that in a blindfold test, it would not be possible to tell a bass modded that way from a German Sadowsky or older Japanese Metro.
