Rich: Had a Trinity College octave mando for a couple of years before I gave it back to the friend I had borrowed it from. Loved it. Played it in AADDAADD Bouzouki tuning more often than standard, but it sounded good either way. It's on the next-to-buy short-list right after the upright bass the wife wants. (Never thought I'd hear her ask me to buy an instrument instead of giving me Hell about the one I did buy!)Bruce
