Sorry to bring up a dead thread, but I own one of these basses

I bought it at the 2009 ISB convention. I initially had the same impression as you (I thought it sounded plain when I played it) but in a blind test it won against a martin shop bass (my other option). I ended up buying it and I'm glad I did! It started to open up after about four months of playing, and three years later, it sounds amazing.
