Cooper, 4 string electro acoustic guitar, with a sapele D shape neck , 16 frets , brass nut and saddle, there's a undersaddle pickup . The body is hollow with the neck going through it, I've strung it with 1-4 strings from a set of electric 11s and tuned to open D , but can string to your preference just let me know. This plays lovely acoustic surprisingly loud and a wonderful tone, and plugged in is great too , a real pleasure to play on . Thank you.
