Wow, this unit blew my mind. I am very impressed by this system. It is super easy to set up and, the TONE! My gear suffer no tone loss with the G30. Comparing to my good quality cables, I notice a huge difference in clarity and tone. The G30 doesn't roll off the top end frequencies like cable does. However, if you do want that to happen, there is a simulator which will imitate this high frequency roll off from cables.
In short - I LOVE this unit and I highly recommend it. I use it all the time now and they only thing I would recommend - get rechargeable AA batteries. The battery life in the transmitter will last over 8 hours but it's a good idea to use rechargeable batteries and keep a few extra in your gear bag, just in case.
