Beautiful Collings MT2 mandola. It's tuned a fifth lower than a standard mandolin: C-G-D-A. The 15.9" scale is a couple inches longer than a standard mandolin scale.
Like the MT2 mandolin, the MT2 mandola features premium appointments such as an Adirondack top, flame maple back/sides, full gloss finish, fully bound body, and a "flourish" headstock inlay.
This instrument has a rich, deep voice that's in the same tonal family as a mandolin but with a lot more low end. It's a great way for mandolin players to get a entirely new sound without switching to a completely different.
