Was your problem with the stock tuners on the MetroLine that they didn’t stay in tune? I had read something about that.
I have a MetroLine coming today from FretNation, it’s a 2023 model, Vintage 21 fret P/J in Alder/Morado. I’ll find out if they addressed that issue.
My last Metro was my first Sadowsky back in 2009, same combo, but the Hybrid with a P body. Loved everything but the weight.
I think this new one should be fine as my future #2 bass. I currently have my dream NYC bass being build, completion date around July/August of ‘24.
