I was given an Otwin Rhythm in the year of 1960 as a replacement guitar for the one given to me for my 9th birthday. That first guitar was a nightmare but I persevered with playing hence I was relieved and detighted when I was handed this big cello bodied single cutaway 'f' holed Otwin.

I was small, it was big but we got along fine and my playing improved no end.

This marque does seem to be a bit of a mystery though, not a huge amount of info available from what I've seen.

I still have it, all these years later as indeed I still have my old Hofner Super 3 which did me such good service in the four years I was in a band in the early/mid 60's

At the moment the Otwin Rhythm is strung for Nadhvill. Records pretty well although not very loud due to the weird string arrangements.

It's best claim to fame was that it was loaned to Bill Nelson of Be Bop Deluxe but am not sure whether he actually used it for recording.

If anyone has info on this model I'd be really interested.

Cheers
