So the big news on this one is there is a crack on the headstock. I had it strung up with some medium gauge acoustic strings and it never seemed to bother it at all but the crack flexes a little bit when torqued upon. I have not screwed it down or glued it which would likely help. The truss rod I imagine is holding it in tighter then it would be if there was not a truss rod and I assume there is a truss rod because there is a truss rod plastic cover although I have not removed it. The action on this guitar was pretty good in my opinion. I'm not sure what the actual wood used on the guitar is but Spruce is a pretty good guess. Please see photographs as they are part of the description. This guitar is sold as is for parts or repair, it has a nice vintage sound. There appears to be a hole that was drilled in it for what we can assume was a pick up. There are various scratches cracks and imperfections but I enjoy the vintage stylings on this guitar.Thanks for looking.
