How to audition the factory presets

If possible, use stereo studio monitors when running through the factory presets. It makes a lot of difference and you'll hear the presets the right way!
Preset output levels can vary from preset to preset.
Some presets may include a noise gate set to a threshold that may not work well with your guitar. Turn the threshold to zero to switch the gate off (Layout menu).
Some presets contain an ENH block (Enhancer) which is for stereo use only. If you're running in mono and audio output is set to “Sum L+R”, Phase cancellation may occur.
Some presets include a Delay block with the Phase Rev parameter engaged. This is a stereo-only feature. If you're running in mono and audio output mode is set to “Sum L+R”, you may not hear any delay trails because of Phase cancellation. Switch off Phase Rev or select output mode “Copy L>R” instead.
When using stereo output mode "Copy L > R" you'll lose signals which are hardwired to the right channel.

Restoring factory presets

When saving your own presets you have to overwrite factory presets. You can restore these at any moment:

from onboard ROM (which contains the original three banks), or
from disk after downloading them from Support. They are also included with Axe-Edit.

Note: the factory preset banks have been updated for firmware release 2.0x. Download them from the website. They are also included with Axe-Edit.
