So I finally got a chance to really crank my new custom Walkabout I got a few months back, and was fooling with the EQ for about an hour or so. It occured to me that I was getting all the tone I wanted from the regular ol' bass, mid, and treble controls, and I wasn't touching the semi-parametric EQ. After fiddling with it, I discovered that I don't know jack about how to get useful tones with a semi-parametric EQ. This is my first amp with one of these things, but I don't feel that I even need to use it. So my question is this: are you actually using your semi-parametric EQs (regardless of amp make)? How are you setting them? What sound are you shooting for?
