The MBT+ metal body tenor is indeed a unique 4-string. This metal body’s scale length allows for the popular “Chicago Tuning” (DGBE) or can be tuned to standard tenor tuning in fifths (CGDA). It is loud and has a very distinct percussive tone. Steel body, mahogany neck, rosewood fingerboard, bone nut, sealed Grover machine heads, and pearl dot position markers. The MBT+ includes a cutaway and a lipstick pickup.
