Nembrini Audio is pleased to launch the Hughes & Kettner Tube Rotosphere plugin, an authentic digital emulation of the acclaimed Hughes & Kettner Tube Rotosphere MKII Rotary Speaker* simulator. Listen to it here and see it here. In the 1960’s the Leslie Speaker System*, originally developed in the 1930’s for the Hammond Organ, began to be used for guitars by The Beatles, Eric Clapton, David Gilmour and more. In the 1990’s Hughes & Kettner, a highly respected manufacturer of instrument amplifiers, cabinets and effect boxes, created the Tube Rotosphere pedal, an extremely accurate, analog reproduction of the Leslie Speaker System.
