Tone of The Queen Age
Brian May’s lead sound on We Will Rock You is about as extreme as you can get from an AC30. Here, you should use a Top Boost lead channel model with gain maxed out and ride the treble as high as you dare. A Tube Screamer-type overdrive effect can help boost gain and treble for definition. Then you can glue the whole lot together with a short medium/bright room reverb for ambience.
