Presets will indeed bring you in the range of the tone that was designed, but your guitar pickups (level and voicing) will still have a strong impact on the tone you will get, and your speakers will also change the results. With multi-effects devices such as the Mooer GE250, presets can be used to obtain a tone close to the preset designer intent. For most preset collections, a copy of the required IRs are bundled within the zip containing the preset files. Take a look at the Impulse Response download page if you want to have a look at the available impulses as well as presentation and usage instructions. For the different presets, the setup instructions are provided.
These presets either use the built-in GE250 cabs or the impulse responses freely available on this web site. These presets are designed and tested for metal/rock and distorted tone in general, but you might give them a try even if you play in other styles. These presets are examples or demos that can get you started or give you some tone and settings ideas. Welcome to this page dedicated to presets for the Mooer GE250 multi-effects.
