I received mine yesterday. All I can say is that for the price, it is good. That said, mine is going back. This is my first SX bass. I have two Brice and a Douglas and like them. But the quality on this particular bass is really lacking.
The Good: The body is nicely shaped, comfortable, and light. The neck is really easy on the hands and the action was low with no fret buzz that I could find. Intonation was close but needed some work. This bass has a double action truss rod which is great at this price. The B string is very clear sounding which is nice on a 34" scale and at this price.
The Bad: The knobs feel really flimsy, even compared to the ones in my Brice basses. The nut is roughly shaped. The tuners are flimsy. The bridge pieces don't feel right either. The pots have that On/Off behavior when they are almost all the way up or down. What made me want to return it was a noticeable nick on the finish close to the nut, a very rough finishing of the fretboard, and a small gouge in the fretboard.
The bass sounds good though. Which is why is kind of hard to let it go. The pickups have strong output and the sound is clean and powerful. There is a slight hum from the neck pickup but I suspect this has to do more with the weak electronics (pots and preamp) than with the pickup itself. I guess that for me to keep it I would have to upgrade the preamp, tuners, nut, and bridge. And at that point I might as well get a different bass.
Kudos to Kurt and crew for taking it back with just a simple explanation of the problems I found.
