A grade Non-figured sitka spruce plank cut archtop guitar meets the grade criteria of a #1 A grade board. These are produced from the finest tonewood fiber in the world. Procured from salvage sourced old-growth Sitka Spruce. Custom builders seldom use this grade, therefore it may be cut special for you. If that is so you will have to let it dry for an extended period before using. Please indicate in the comment section of your order what size instrument you are building.
