As Simon told me, I sanded a little bit the neck to get a more confortable shape
Also the body has been sanded today
Them, afther some test on a piece of wood similar to the guitar, I decided to stain it with a lightly red mahogany color.... Now It´s drying, but later I will post a picture.
I found a little defect on the body in the joint of two pieces of wood... and there the stain make it more noticable.. but It´s ok. I will see afther the second stain layer....
