if you want to disable the amp and cabinet, you can click/drag the amp and speaker option so that they are: “Direct" and “Transparent PreAmp.” However, you might also try out different amp models in the template with a low gain setting into your template (Some folks actually like to run the amp modeling in combination with with a tube amp when using Sunday Guitar).
