I've seen a video here; and wondered if there is something similar on the 15? The reason I ask is trying to find a baseline to adjust the presets; for example, if I set all dials to max then 'factory reset', all the settings remain at max: same with min. Is there a preset setting, or am I getting the wrong idea and the amp is just emulating the sound of a type of amp and the settings are all your own? Cheers
