Is there a modification that can be done to an Egmater dual Twin to change one channel(mayby a bit more gain or something). I love the tone but don't find I can get a lot of variation between the two, seems like a waste of a channel. It's super clean all the way up until totally cranked, then it's way louder than all my other channels. I have an electronics degree and can follow a schematic if anyone knows of a good mod. Or even if someone does them.
