Hi
I'm doing some change in my setup and want to use two transmitters and one receiver for a 2 guitar setup.
I have seen that the G90 have an A/B function so it easily can change between two channels. The G55 does not have A/B but it has a channel select knob, so it is very easy to change channel.
Is there any technical difference between the G90s A/B function and selecting channels with the knob on the G55? Is the A/B function faster than a regular channel change? Do the G90 need to "lock" the transmitter when you use the A/B or is it just a user-friendly way to change channel?
