Scored this one on eBay recently.
Listed said it was a LB-75, but from what I can find, the offset dot markets were only available in the BB-75. It feels like the neck matches the asymmetrical profile that the BB-75 has, but I've never played another Carvin 5ver to compare.
The only thing that makes me wonder is it doesn't have any Bunny markings, and I can't find a pick of a BB bass with the side jack and only 4 knobs. (Fwiw, seller recently upgraded to the newer Carvin pre, hence the stacked chrome knobs. Need to get black ones)
