Thanks, yes indeed, I perfectly set up the bass the day I got it, from neck relief, to saddle heights, to intonation.
I liked the pickup height so I left it as it was from the factory.
I don't suspect anything on the bass, it is fantastic, and it sounded fantastic with the previous SS strings on it.
Again, not comparing the fact that SS strings sound brighter than Nickel strings, which I'm aware of, that's not the issue here, the issue is that the A, D and G sound bright enough, the E is completely dead like an old string, and the B sounds like it's a month older than the A, D and G or so.
I don't usually rule out user error issues quickly, but I looked everywhere til now, I really can't see.. A bit lost and confused tbh
