so, once i have a preset, any preset, amp. cabinet, whatever, if i want to make a slight change to it, like volume or drive or whatever, i can do that with the knobs on the top, then save it.
i dont have an iphone. and i dont wanna have to mess with an ipad on stage if all i want to do is turn up the volume on my clean channel a little. I have the shortboard mk 2..
