Beautiful charango in excellent condition. No label or brand is visible inside the instrument, only some remnants of glue, but it's clearly a quality instrument with a beautiful authentic sound. There are some minor signs of use, 2 small dents in the soundboard varnish and some rust/corrosion on the tuning mechanisms, but they're still smooth. There's no damage to the wood or other parts. Traditionally tuned with nylon strings in double courses G C E A E with the middle E in octaves. Including a traditional colourful woven gigbag and instruction booklet from the possible builder and teacher 'Pedro Mar', but I can't find enough info to be sure who build the instrument. The booklet seems to be dated from early 2000's and has always been included with the instrument. There should be a CD present with the booklet but unfortunately only the box remains and the disc is missing. #bestofmusicf
