Vintage Synth Explorer Forums

Just remembered that I had a Hohner k4 hidden away in the shed. I haven't played it for years. The one thing I remember is that it was very heavy. Did it give a good sound and would it be worth cleaning up with a view to selling? I vaguely remember it was a little limited in its scope but it did a job. I am sure someone on here has one or remembers how they sounded.
Thanks
