I recall attending the Australian launch of the G3 Wireless range a number of years ago and was at that time very impressed with the upgrades these systems received. The G3 technology in both the transmitter and receiver leave no sound unheard and the frequency range delivered to your amp is exceptional. It was difficult to discern the difference between wireless and wired sound.
One of the huge advantages of the EW 172 is the range of channels and frequencies that it can be operated on. This allows for large numbers of wireless systems within an area to operate independently without the fear of crosstalk or interference. This true diversity system ensures your guitar signal is delivered to your amp without a worry. Automatic channel scanning sets the system up to work in the best possible way as the quick setup gets you ready to play in moments. Housed in a sturdy metal casing with the option to house within a rack for touring rigs, this is, and continues to be, the wireless system for the serious live guitar player. When you also take into consideration the added extras that Sennheiser have included like built in EQ, soundcheck mode and tuner, this is really a no-brainer.
