Mobius Megatar was the company founded by the illustrious Traktor Topaz, inventor of the Megatar touch-style bass. Instruments were sold all over the world under that name for many years.
As of Mid 2014, long time Production Manager for Mobius Megatar took over the company, redesigning the instruments and the brand. Among many changes was choosing to leave off the Mobius and just work with the name Megatar.
Megatar still supports older "Mobius" instruments, and the New Megatar is essentially just an evolution of the already successful classic mobius instruments.
