Catalinbread Galileo Brian May in a Box pedal.

AC30 amp sim driven by treble booster. Cost €180 last year. Used at home a few times. Never gigged. From the website;

"Captures the regal and soaring tones of a Rangemaster Treble-Booster into a cranked up Vox AC30

"Queen in a box"

 Brian May’s sonic signature not only comes from his home built “Red Special” guitar, but also from a treble-booster pummeling banks of AC30s. He never turns the treble booster off, accessing a wide range of tones simply by manipulating his volume knobs and pickup settings. From his guitar, to the treble booster, to the amps, his entire rig is essentially a singular musical instrument. One that inspires the sort of playing May is known for. We designed the Galileo with this playing approach in mind, that with it you can roll your guitar volume back for jangly AC30 cleans, and crank it up for searing leads and aggressive yet focused rhythm tones".
