This Lil' fella is made from box elder with a chestnut soundboard and zebra wood accent. Comes with a Poplar striker. I enlarged my regular size by 1 -14" lengthwise and added 3/4" to the height, I kept the inside the same, concerning the distance from the inside wall to the inside of the soundboard. I added the port in front it raises the pitch, when you cover it and play the box it is a lot lower. Kind of like young hen old hen thing. I also tapered the sides from bottom to top to fit more comfortably. She sings bird for sure, headed to the classies....pappy
