Yes, I own an Otwin Jumbo of 1965. It is a copy of the Harmony Sovereign with all solid woods (spruce and mahogany). It's a beautiful and strong sounding guitar which I use frequently with K&K Pure Western Mini pick-up on a Roland AC90, a very strong combination. It has a totally different sound than my Larrivee D03 and Ayers ASO, with much more mid. I guess I will never quit from this piece of art!
