Beautiful. I'm with you on the MG body, and also with the subtle issues that happen with light basses. I chased lightweight basses for a couple of years but actually Jason finally cured me of that. I also began to notice that nearly all of the really light ones had some degree of neck dive, some worse than others.
And agree on the can't stop practicing. Typically on a non-gig night I'll spend an hour or so running exercises and tunes I need to work up. This last weekend it was averaging 3-4 hours with the MGS comping tunes and working on things. It has opened up a completely different area for me on the instrument. I love this bass, though I now know I need a chambered walnut body with some crazy top and ebony fb just because.
