Sennheiser EW100G4-CI1

The ew 100 G4-Ci1 is a UHF wireless instrument set for electric guitar and bass. It pairs the SK 100 G4 bodypack transmitter with the Ci 1 instrument cable, which takes the 1/4-inch output of a guitar into the bodypack, and delivers the signal to the EM 100 G4 rackmount true-diversity receiver. It frees a player from the cable without reshaping the tone.

The G4 platform tunes across up to 42 MHz of switching bandwidth with 1,680 frequencies in 20 banks, and up to 12 systems can run together after linked-receiver auto-setup. Sennheiser's HDX compander keeps the noise floor low, and the bodypack runs up to 8 hours on two AA cells.
