Hi. Can someone try to explain how can I get that my Spider IV remain with the same volume when I go through differents effects? Sometimes, the difference is so big that I guess I will not be able to use that amp in public session, cause it will probably bother the audience.
Adjust the 'Channel Volume' for each of your different presets, make sure to save your changes. Say for example you have two presets, switch to your preset#1, set the 'Ch. Vol.' for it, save it. Switch to preset#2, set the 'Ch. Vol.' for it, save it. Go back to #1, adjust as necessary - being sure to save each time.
