Like I said, I love the bass and am not bashing it by any means, but the set-up could have been better.
That said, and to be fair, I had one shipped and didn't bring it to a luthier until 6 months later after a teacher suggested I do so. I had only owned crappy old basses up to that point and even with the set-up as it was, the Wan played way better than anything I had owned. After I had the work done, the bass seemed much freer both in sound and feel and was easier to play.
I guess the lesson is that if you have any instrument shipped for a test drive, it is a good idea to take it to a luthier in your area immediately and have him look at it to see what adjustments might be necessary. So Alek, l suggest that you take it to a luthier and let him look the bass over top to bottom and see what adjustments he suggests.
