Hi! So I just randomly played one of these at Guitar Center and I was really digging in on the Mezzos with treble full and bass in center. I played the metallic purple finish and instantly fell in love with the tone (not so much the color although my gf and I were joking about the color giving such Prince vibes). After playing the bass I had one guy ask me if I was playing an expensive bass until I showed him the price tag. He literally flipped and asked if I was buying it or not. Long story short, he ended up buying it which led me here.
I might consider buying it if I weren't so attached to my other Basses I own (I seriously need to stop looking into more basses...) but if there was one flaw to point out on the bass was the narrow neck around the 3rd fret. Perhaps something I need to get use to but I was also thinking of upgrades for the Mezzo. Given it's extremely bright characteristics I'm not so sure if I'd want to tame them or embellish it even more. I feel like if it sounds good as is, don't bother with upgrades. Plain and simple. Enjoy the bass as it is and if you really want to change the way it sounds either look into a new bass or find some strings that will help with what you're looking for.
Because people have asked in this thread about upgrades I'd probably upgrade the machine heads, bridge, and pick guard
