Glenn's tone is produced by playing humbucker-equipped guitars. Compared to Downing's tone, Glenn's tone is warmer, with more bass and lower mids. This lets both guitarists play the same parts yet remain distinct in the mix. Tipton's "classic sound" on albums like British Steel, Screaming for Vengeance, and Stained Class was obtained using 50 watt, non-master Marshall heads with EL34 output tubes, and a Range Master treble boost – a device also used by Brian May of Queen. During this period, Glenn also employed a MXR Distortion +, Phase 100, and digital delays, as well as an old Maestro Echoplex.
