MB-4 SBK Deluxe Series : Cool bass, but with quality issues

I've had several HB basses over the years, and my current go-to is a modded PB-20 SBK. So, I wanted to try the MB-4.

What I liked:

- The tone

- The neck (very enjoyable profile)

- The look

What I didn't like:

- Two pots were very gritty, one very difficult to turn

- There were paint blemishes on the fretboard and a small one on the neck

- The pickup screws are at weird angles making it extremely difficult to adjust pickup height (a common issue with HBs in my experience)

If it was any one of these points alone I would have kept it. But all three was just too much for a "deluxe" bass. Seems QC is worse then on my "standard" PB-20 (and the MB costs around 40% more). I was a bit sorry as the tone and playability are pretty good.
