I will say this and I'm sure many will disagree. In my experience, the German Sadowsky preamp does not sound like the NYC pre. I've owned a couple German Metro's and also had the onboard German preamp installed in another bass. I've also owned many NYC's and my main bass is the NYC in my profile pic. For whatever reason, it seemed to me the preamps respond differently and sound a bit different, it's a bit hard to explain.
Question to those that own a German metroline, is the preamp in your bass TOO sensitive? I just got a new metroline 5 string and the controls are way too responsive, like 100% of the bass freq is in the first 5% of boost, also the VTC and the treble get super bright like within the first 10% of boost, I will be recording a video to show this to Warwick but just wanted to ask if any of you have the same thing happening to you? I have owned about 6 or 7 sadowskys (Japanese and Germans) and I have noticed it more on the last 3 Germans that I have owned
