Well I just got back form the store where I played a 2003 model of the bass, in amber burst, (it was a five string) It sounded good but I wasn't overly impressed. It felt amazing I,ll give it that much, it was very smooth. It weighed next to nothing (I was looking for a heavier bass but meh.) Sound was, it didn't blow me away. It didn't have too much growl or all that much mwah, and it got really twangy when i tweaked one of the knobs. It looks super nice, I love the whole f-hole thing. The guy at the store said to call back on Tuesday and he would check with Spector custom shop to see if they could do anythign with better wood and an ebony fingerboard etc. What woods make good semi-hollow bodies? (the guy said maple).
I also played a Fender MIA fretless with flatwounds that I really did not like, and I played a Yamaha 5 string that sounded really good, but unfortunately for me it was a 5 string.
I'm actually pretty nervous about the CArvin incase I don't like it, but it certainly seems to be a better buy than the SPector. They are also alot uglier than Spectors.
