Q: Why do presets I built from scratch sound different than similar factory presets?
A: When creating new presets from scratch and comparing the tone to an existing factory preset with the same settings, please remember to check the mixer settings of that preset to see if they may be different than how you have it set in your own preset.? If the mixer settings of the factory preset are different than the mixer settings of another identical preset, they can both sound different than each other even though they share the same amp model and tone settings. The mixer settings are saved per preset and are NOT global.
