These look and sound very interesting and are being used by many well known musicians.
Here’s how it is tuned:
1.G# , 2.D# , 3.B , 4.F# , 5.C# , 6.G#
(The same as placing a capo on the 4th fret, but it sounds different because of the nature of design)
There’s an assortment of accessories too, including a lap-steel kit. I like them a lot.
