I am in the process of improving the playability of this Sanchez guitar History- i bought this guitar in 1975. I went my local music store(AceMusic) in NMB Fl. Long since gone. I rode my bike over with$50 in hand and walked out with this. At the time I was very green when it came to knowing what I had. First thing I did was to take off the strings and put in electric guitar strings. Screwed in strap buttons and learned Kiss and Ted Nugent songs lol. I eventually changed things back but the actual relicing has taken place over the last 45 years of my abuse. I am wondering if anyone could help me figure out what year this guitar is? It was used when I bought it and my research has dated it anywhere from late 60’s - no later than when I got it which would be 1975 but it is older than that. There is no serial number I can see. The model is A- 200. So curious about the wood. i am thinking the fingerboard and back appear to be rosewood. Being that it was made in Brazil I would think Brazilian rosewood. The top looks to be sitka but not sure. It is a gorgeous instrument. I lowered the awful high action and it plays great. Still looking to maybe get a new saddle piece and improve it more. Here some pics. I just put on La Bella flat wounds. Any idea on Year and wood species?
