Evidence

Why we think this is right

This is one of the best documented rigs in rock, and the interesting part is how little of it changes. The Red Special, a treble booster and a Vox AC30 on the Normal channel produce every guitar sound on the record; the difference between the soft answering figures under the ballad, the solo and the heavy section is Brian May's right hand and the guitar's own volume control, not a channel change or a pedal. We have written the three scenes that difference actually produces and merged the closing section into the ballad scene because it is the same sound. The long opening and the operatic passage carry no guitar and have deliberately been left without a scene.
