If you’re talking signature guitar tones, we’d wager there’s none more instantly recognisable than that of Brian May. Ever since Queen’s debut album five decades ago, a whole industry has grown up around ‘that sound’, with guitars, amps and effects all vying for the attention of hordes of Queen enthusiasts who want to replicate it. 

Aside from the ‘Red Special’, May’s unique homemade guitar, the other main component is, of course, the Vox AC30, which May plugs into via a variety of treble boosters.
