The wenge/maple NT, rather than the maple/walnut veneer laminate version the two years before. Probably won't make any difference tonally or structurally, but it sure looks sexy and would look good next to my Cort A5 Ultra Ash and if I'm gonna have to import one, I might as well wait for the one I want. For the same reason, I'd like a BTB1826/1906 too.
I have a BTB846v that's waiting to become a large Bass VI, strung E-E, just need to custom order the strings, and because it has 16.5mm spacing, the neck feels very similar to the SRs.
The other BTB 6 and 7 I mentioned are from a local who's looking to move them along, and being in the middle of nowhere, they're hard to sell - also because of the string counts. I have some expensive car repairs to fund in the short term, but he's in no hurry.
