I've been intrigued by this bass and just thought about it the other day. I will never buy another Hagstrom instrument, though. I bought a "new" Hagstrom H8 Retroscape and the thing, although sounding tremendous, had horrible build quality. The truss rod was broken inside the neck (you could hear it rattling around), fret sprout and fret work were atrocious and overall it felt very cheap and plasticy. even with almost half off I still didn't keep it.
Try a Swedish-built one the next time around. Sure, they cost more but they are well-worth it if one is into Hagstrom design/sound to begin with. My Hagstroms were the only basses and guitars that never required truss rod adjustments.
