Hi, I bought my Harmony Opus v about 10 years ago for £100 in a second hand shop in Swindon, Wilts, UK, It is such a lovely guitar, it has quite a few dings on it but sound amazing, it is a joy to play, but has had a ROUGH life until I rescued it, I LOVE IT… I dont know how much it is worth, but I have played Taylors, Takamines, Gibson, and Martins and this is better…
