Explanation of a harp guitar
 

Hi there,

I'm looking at what harp guitars are, having heard of them yet never knowing what they are. From this video, I can see that it accommodates some very low bass strings for fingerpicking.

Is that all there is to it? Any more information would be appreciated.

Gregg Miner has a bunch of historical and other information on harp guitars, you can take a look here http://www.harpguitars.net/history/org/hgorg.htm

I was at a concert a couple months ago where a guy played a harp guitar for one of his songs. He never did hit any of those extra bass strings, just the regular 6 guitar strings. He explained that the extra strings were just there for the sympathetic vibes. The thing sounded amazing!

Right! Even if you don't play the subs, or don't play them much, a harp guitar still sounds amazing and like nothing else. They are also remarkably loud, that huge top area really rings out especially at lower frequencies.
