Martin is making a small edition of Brazilian rosewood dreadnoughts, called the D-28B and D-45B.
They were offered for sale at Summer NAMM in Nashville (currently happening this weekend.)
I remembered to ask about this while having lunch with a group of folks from Martin executives and senior management, just before I returned to NYC. They could not remember off hand exactly how many D-28B and D-45 guitars are being made. But it is an equal number, and Martin dealers are required to buy one of each if they want any at all.
So to be able to sell the $20K list price D-28B, a dealer must also purchase for sale the $45K list price D-45B. Prices are approximate, as they were speaking off hand in a restaurant out of town, so the specifics where not readily available.
As for construction, I was told "pretty much Golden Era Series specs." As this all happened on a few minutes before we parted company. So that is all I learned.
** UPDATE** Here is what I know now.
They are making 15 D-45B instruments. They are making the same amount of the D-28B.
Both instruments are made with hide glue construction throughout.
Both instruments have Grade 8 Adirondack spruce tops.
Both instruments get bracing pattern DOMLE #3A, which I believe translates to "forward shifted." (DOM means 14-fret dreadnought, LE means limited edition, i.e. not standard.)
The 45 gets GE scalloped bracing.
The 28 gets Standard scalloped bracing. (i.e. Vintage Series, D-45, 42, 41, HD-28)
Both instruments have the traditional fingerboard taper.
The 45 gets a 1-3/4" Modified V neck
The 28 gets a 1-3/4" Low Profile neck
Both instruments get the drop-in long saddle with 2-5/16" spacing.
The 45 gets grained ivoroid binding
The 28 gets Antique White boltaron binding.
The 28 gets the fine herringbone purfling, long-pattern diamonds and squares fret markers, zig-zag back strip of the Marquis/GEs.
The 45 gets the snowflakes fingerboard, mitered corners on the purfling, and wood fiber trim of the Marquis/GEs.
Both instruments get Aging toner, but the 45 does not get it on the purfling or rosette. (Same toner currently used on the Standard OM-28 and new D-28.)
