"All the guitar you will ever need."
Lots and lots of bass, but still has plenty of mids, but a little light on trebles. The standard, non-scalloped bracing is the same type Martin used back in the 1940s. Actually, not much of anything has changed about the D-28 since the 40s. If you do it right the first time. . . . .
One a speck of abalone on this guitar. When you buy a D-28, your money is buying JUST an acoustic guitar, instead of all the artistry you see on many other makes and models. High quality Sitka spruce and East Indian Rosewood with ebony fretboard and bridge. Simple white/black/white rosette and binding.
Surprisingly high grade tops for this price range, and, like all Martin guitars, is hand made to some degree. The "Standard Series," of which the D-28, D-18, D28HD etc. belong to are all hand-fitted. Bridges, saddles, nuts, frets, you name it, are all put together by Martin guitar builders, some of whom have been with the company for generations. They know how to make a guitar!
The finish is always supurb.
They have a call-in number, as well as fax and e-mail numbers, with same day or next day answers.
I would be very hard pressed to name a guitar of equal value for it's surprisingly moderate price range. There are plenty of guitars that cost much more that can't hold a light to a D-28
The Wow Factor:
Playing one shows you know the value of a dollar, and are willing to wait until you find the best. The most recognized guitar in the world. Most people think "guitar," and they think Martin.
You'll never feel the need to upgrade to a higher-end guitar after you buy a D-28. It's perfect the way it is, so please leave it alone!
I make sure I have this guitar insured for it's list price in case it gets stolen, or I lose it to some natural disaster.
