The Martin HD-28SE was guitar of the month in September 1986. It had the HD-28 style body, herringbone top purfling/ivoroid binding, diamonds and square fingerboard inlays, tortoiseshell pickguard under finish, ebony tuner buttons.
Only 138 Martin HD-28SE were sold (130 in the USA and 8 elsewhere) and they were all signed by C.F. Martin III, C.F. Martin IV, and the Martin company foremen underneath the top.
This model should not to be confused with the Martin H-28 Sweetwater Edition sold via Sweetwater.com.
