Oh my. If you like fun, and you like guitars, you have just arrived here at the place for fun. A long time ago my band played a show in Boulder Colorado with a band called Human Head Transplant. It is a fond memory. My recent purchase of this guitar brought them to mind. Maybe this is a Barney Lopez. The headstock of this guitar is NOT stock. It seems to have been transplanted. I think I can see that and will add more pictures. The tailpiece is vintage Gibson but does not mention Trini Lopez.
