Hey look it's a thread here I can actually contribute something to... I had one of these basses a few years ago
I got mine at a local GC in the late 90s when they were new, mine was the "black sunburst" finish although they had some all black ones when I was there. (Maybe some were darker than others, yours looks really light compared to mine) ANyway I really liked how it sounded and played, but the neck on it warped terribly in about a year. LIke the frets sprouted right out of the neck, I adjusted the TR pretty much as far as it would go and it would still buzz everywhere. I did take it to a real repair guy who couldn't fix it and advised me to return it but of course it was way out of the warranty period. (and yes I kept it in correct humidity, it gets dry here in the winter but it was in my music room the whole time I owned it). I ended up scrapping out all the hardware to get my Hofner playing again. The pups sound better in that than they did in the Gretsch IMO.
EDIT to add, just keep track of the neck, I don't know if the Chinese ones are made any better than the Korean ones. And a friend of mine had one of the one pickup ones and it turned out to be plywood. The finish looked the same as my 2-pup one before he took the belt sander to it.
