I just strung up this Koa/Bear Claw sitka 00 12 fret short scale 00. It is a tradition build for me with a Martinish style X-Bracing, no carbon fiber or epoxy. The pore fill is System 3 Silvertip epoxy, I apply it and sand it back until I can level sand it with no sand throughs. I sealed it with Seal-Lac (shellac) and sprayed post-cat Royal Lac.
