In this video, I show how to set the correct Input Level on the Axe-FX II, which is really just setting the optimal signal to noise ratio. It doesn’t affect the gain or tone of your preset unless you have extreme low levels that don’t give enough signal or high levels that constantly clip.
If you set the level to 100% and you aren’t making the red clip lights turn on, it’s ok! We don’t want any clipping and whatever level you set that doesn’t make it clip is a good level to create your presets and use the Axe-FX.
If you use multiple guitars, it’s suggested to just set your Input Level for your loudest guitar and leave it set there for all other guitars as well. Remember, real amps don’t have an input level adjustment.
Make sure to turn your guitar volume all the way up when setting the level and to switch to all pickup configurations to make sure nothing causes Input clipping!
