What is that, about a 78" scale?? Yeah, you probably won't want your theorboist to be dancing around much on stage.
The first college I attended, finding themselves in financial trouble, tried to negotiate a deal to share the campus with the School Of The Lute (which taught/teaches both playing and lutherie); they came to do a concert & played many varieties of lute - but nothing like that thing! Way cool - but I'm thinking a harp guitar is easier to get across town on a bus.
