The M-7 Johnny Marr is a seven-string on Martin's M-14 Fret body, the 0000 size Martin calls a Grand Auditorium. The seventh string is an octave G, so the G course is doubled as it would be on a 12-string while the other five stay single.
The rest follows the M-6 Johnny Marr: East Indian rosewood and spruce with an Antique Toner gloss top, scalloped X bracing, a Full Thickness genuine mahogany neck with Standard Taper, and Style 28 inlays on an ebony board. The bridge is a modern pyramid 7 string design in ebony with a compensated bone saddle, an LR Baggs Anthem is fitted, and it comes in a hardshell case.
For the six-string version, look at the M-6 Johnny Marr. For every course doubled, the 12-strings in this catalogue are the HD12-28 and the Grand J-16E 12-String.
