I have a 1978 Yamaha FG335 which I bought new for £93, the sound is excellent, a lovely bass tone if a little light on the top end. I wouldn't sell it basically because I would not get what I think it is worth, a guitar of this quality today would cost upwards of £700 and the second hand value is probably closer to £100 besides which my girlfriend of the time gave me her tax rebate to buy it and now she is my wife she'd probably kill me if I sold it
