The 1024x is all that the 2024x is accept for being made in Japan and ARE technology. It has an upgraded bridge, same pups, spline joint, string thru. I had one from Nova Musik. It was almost perfect, had an annoying buzz on the second fret, E string. I tried everything to eliminate it but could not. There did not seem to be any high frets. I thought that the truss rod wasn't functioning as it should. I ended up speaking to Yamaha tech support and the bass went back. Honestly other that, it was damn nice. Maybe just a lemon.
