I don't know much about this bass except that it's visually stunning and in almost perfect condition - and it plays and sounds great. I've played it on a few gigs over the years and a few recordings, but I'm mostly an upright and fretless player so it hasn't had a lot of use. I think it had a custom EQ of some sort that the previous owner kept for some reason, thus the extra hole in the front. It seems like their high end model but I'm not that familiar with the BTB line to know for sure and I don't know when it was built. There are a couple small scratches on the side, one on top and one on the bottom, otherwise no noticeable dings...I bought it fr om a guy in Portland in early 2000s.
