The generator provides radio frequency, which is essential for the procedure, and connects the foot pedal system to the tonsil wand. The foot pedals are colour coded to prevent confusion: one is yellow and is used for controlling the coblation, while the other is blue and used for controlling the radio frequency cautery. The wand is connected ...
The first use of pedals on a pipe organ grew out of the need to hold bass drone notes, to support the polyphonic musical styles that predominated in the Renaissance. Indeed, the term pedal point, which refers to a prolonged bass tone under changing upper harmonies, derives from the use of the organ pedalboard to hold sustained bass notes. [2]

In late 1983 MXR announced a digital sound effects pedal generator simply known as the Junior. The Junior was released in early 1984 and was added to the other six pedals in the Series 2000 line.
The PTX8 has mixed stereo L/R outputs and 8 individual outputs (one per Tone Generator). When none of the individual outputs are being used, tone generators are panned across the stereo output. Tone generators 3 & 4 are panned left, 1, 2, 7, & 8 are panned center; 5 & 6 are panned right.
The effect (now named Uni-Vibe) was modified to have easier access to its fuse, and a speed control foot pedal was added. It was later released in North America by Univox in 1968.
