The shallower body makes playing more comfortable, especially for the right arm and shoulder.
Unless a comparison was performed with the shallower body dreadnought compared to a full dreadnought, it is difficult to determine if there is any tonal difference.
When plugged into the amp, the voice on the D-16E appears to deliver the full dreadnought sound.
As with most of the Martin 16 Series, the D-16E is a great value. You are paying for great materials and great sound whether acoustic or electric.
If you’re looking for a dreadnought with great sound and comfort, then you owe it to yourself to check out the Martin D-16E.
If you aren’t sure about the shallow body dreadnought check out other acoustic guitars.
