Title says it all. There can't be many. Only made 3? years if I recall. The full system in 1968 was $3, 695. I know the who had one for their first u.s. tour, hendrix reportedly used up to five, mountain maybe had a few, it was designed for the beach boys, etc. I love mine to death. I bought the first one I had ever seen for sale. Since then, I've seen three others pop up. Also, do we know how many were at woodstock? Thanks!
