Believe it or not but the PSR 500. I'm country all the way and it had a pedal steel guitar sound I have not been able to replicate. I also have had a couple of synths I wish I hadn't gotten rid of like the Kog poly 61. Also had a neat little accompliment unit that I sold. A something xx50. Used tape cassettes to save songs on it.
