Sourced from interoir Northern British Columbia in Canada, Engelmann Spruce is very white.  The annular rings tend to get wider on one side, although occasionally you will find evenness across the grain.  Engelmann trees are smaller than Sitka so the early growth (wider lines) are used to get the width of a soundboard.
       AAA and AA sets are vertical (quartercut) sawn for 90 degress.  A tolerance up to 75 degrees may occur; however, this affects the stiffness.  Engelmann is lighter than Sitka and good for steel or nylon string guitars.  Most of this wood is aged 10 years or more. 
    The EH series is from an estate and was first purchased in 1995.  Stored dry since then.  This is the remainder of that purchase by Erica Heyligers of Woodshine Finishing. She is Missed.
     The other woods were from a few different sources.
