Factory presets demonstration

When saving your own presets, you have to overwrite factory presets on the Axe-Fx, unless you have a XL (Banks D and up are empty).
You can restore the factory presets by downloading them from Fractalaudio.com and loading them into your Axe-Fx II using Fractal-Bot or Axe-Edit.

The Axe-Fx is sensitive to the type of guitar you're using in regard to presets. For example, use a guitar equipped with single coil pickups when auditioning Fender amp presets.
When hitting the strings in a normal manner on a guitar equipped with single coils, clean factory presets should not distort. When really digging in the strings, especially using a high-output humbucker, some clean presets may distort. Don't worry, they should probably be getting distorted, based on their settings. If you don't like that, just turn down Drive or Master Volume or Input Trim in the Amp block.
Preset output levels can vary from preset to preset. If a factory preset makes the Out 1 Clip LED blink, its overall signal level is too hot. Turn down Level in the Amp block.
If possible, play the factory presets in stereo to hear the presets at their best.
If you're running mono and audio output is set to “Sum L+R”, phase cancellation may occur. This can happen if the preset contains an Enhancer block in Classic Mode, or a micro delay in the Cab block. Or when a preset contains a Delay block with the Phase Rev parameter engaged.
When using output mode "Copy L>R" you'll lose the part of the signal that's hardwired to the right channel. That might be a Ping Pong delay, or a stereo Cab block with both sides hard-panned.
Cliff: "The presets were dialed in loud so as to be sure the Fletcher-Munson effect did not influence the sound." source
