Yamaha RBX6JM

The Yamaha RBX6JM was the first John Myung-signature six-stringed electric bass.

A bolt-on bass with alder body and flame-maple top available in either "Ruby Red" or "Turquoise Blue" with a maple neck, ebony fretboard, gold hardware, 35" scale, and "Infinity" dot inlay on the fretboard, various Red and Blue "RBX6JM" models were his main studio and live instruments along with his TRB fretless from 1997-1998's [http://www.mikeportnoy.com/dates/tourography.asp?menu=dates Touring Into Infinity] , 1998's "Once In A LIVEtime" double-disc live CD and "5 Years In A LIVEtime" video, 1999's ', following tour and 2001's ' DVD and "Live Scenes From New York" three CD live set.

Changes included a modified body shape with more "modern" lines and carvings, finishes in either "Inca Silver" or "Plum Purple" in flat as opposed to glossy paint, slightly tighter string-spacing, a maple neck/rosewood fretboard with "Yin-Yang" inlay at the 12th fret, 34" scale as opposed to the 35" scale that the RBX6JM had, and most importantly a single Music Man-style Seymour Duncan SMB6A humbucking pickup, by all accounts an influence from his usage of a Music Man Stingray to record a good portion of Dream Theater's "Six Degrees of Inner Turbulence".

In July of 2007 Myung officially endorsed Music man and their new six-string version of the Music Man Bongo bass guitar. John's current status with Yamaha is unknown.
