My overriding memory of the EKO 12 string I also bought in 1969 was its WEIGHT - it was built like a brick shithouse.

I use to ride my 650cc Triumph Thunderbird with it strapped over my shoulder on the way to gigs. God I was cool . . . (legend in my own lunchtime).

It had a lovely action and I seem to remember the edges of the frets and fingerboard were really smooth and comfortable.

Have fun.
