Mine weights 2.8kg. The black one in the video above about the DiMarzio pickups weighs 2.95kg. So mine is maybe lighter than average, or the neck is heavier. How heavy is yours?
When I play sitting down it tilts down to my legs. The strap buttons are where they're supposed to be. I bought it online from another city. Returning it would be a hassle and I don't want to because everything else about this bass is perfect, I got a good one. I guess I'll have to live with it.
Mine weighs almost exactly the same as your, in fact mine might be a hair lighter. Interesting. Maybe it's the angle at which we hold our instruments.
