Hi, I'm new to my Spider Jam. I'd like to create a User Tone of my own just from the amp models and the onboard effects. It doesn't seem like there is a way to bypass the Preset Tone that is currently showing in the screen. Is that the case? Do you have to work from an existing preset tone to build a new user tone from that? Or is there a way to get a "blank" tone to start building from scratch? I hope my question makes sense, and someone can steer me in the right direction. Thanks.
