Though it's been a few years, Blue Book used to gladly welcome input, particularly photos, & established dealers passed along experience with prices & demand.
Though they have their gaps, they sometimes take pains to delineate different versions -- for example, the MG-200 Special, or the D-29/-30/-31. Then again, they confuse the X-40 with the X-40PRO.
They don't do much about the HB-35 because they don't believe many people are interested. That's where fans come in. And I can say from experience that I have become interested in a few off-brand guitar models or lines, asked some intelligent questions, written a handful of articles, & watched online interest climb.
Most people who love the HB-35 already own one, & one only. Sure, maybe they'll upgrade to an older classier version -- like from an MIC to an MIK -- but that's about the limit of their interest. And while a credible shop would gladly take one in, the model just isn't valuable enough or "sexy" enough to make it some sort of specialty.
Like, well, this has been hanging around almost half a year, now asking a mere $550.https://reverb.com/item/2414871-1984-washburn-hb-35-natural-finish-made-in-japan
Seller says it's 1984 --
Even with the MIJ cachet AND the case, there's no interest worth mentioning.
So, yeah, people need charts & graphs, they need to be able to tell how to determine whether a particular HB-35 is farily priced. Keep up the good work.
Something interesting to me. Here's a 2012 labeled "Made in China" & the factory code is DC.
Yet, one from 2014 has a G code.
Maybe there's some compare/contrast that can be done between factories' product.
In what years was the five-piece neck used?
And what the heck is up with the Roving Knobs???
