Based in Asheville, N.C., Nada Lutherie is primarily a maker of ergonomic bass guitars, but has built a few electric mandolins. I don't have specs for the one on the left, but the one on the right features a chambered sapele body, Graphtech piezo pickups (expandable to 13-pin) with acoustiphonic preamp and mid/dark switch, Bill Lawrence L-500xl magnetic pickup, purpleheart bridge, flame maple top, 1-3/8" bone nut, purpleheart truss rod cover matches bridge, 13-7/8" ebony fretboard, and sapele neck with LMI truss rod.
