Piece of Mind Gallop — Twin-Marshall Rhythm
The song’s attack comes from two complementary humbucker-equipped guitars into loud Marshall amplification, with moderate gain and pronounced upper mids rather than modern scooped saturation. Period interviews and later tone guides consistently place the early-1980s Maiden sound in the Marshall 100-watt/JCM800 family, but exact song-session settings are not published. The controls below are therefore representative of the documented era rig and established reconstruction settings.
