I've only had this bass a couple of weeks, but I have to say that I love it! It feels , looks and sound fantastic.
The build quality is excellent. There are no blemishes, rough edges or other flaws. The frets are well finished. The hardware feels solid. The colour is probably a bit more blue than it appears in the photos, but it's gorgeous.
The neck has a very modern, fast feel. There are no dead spots, fret buzz or anything else to detract from the sound. The action is amazingly low. There's a little bit of neck dive (as one would expect from a Jaguar), but nothing too serious and it's easily overcome with a decent strap.
My only slight niggle is that the sound is a little bright for my taste. With that said, it is a new guitar with new strings, so it may mellow over time. Equally, it might inspire me to shift my playing style to suit the instrument; it's a good enough bass to merit that!
A friend of mine (formidable guitarist with 40+ years of experience and professional playing) popped over to see it. He looked like an excited six year old child who had been let lose in a sweet shop! He was completely blown away.
Overall I love this bass and really can't praise it highly enough. It looks amazing and sounds great.
