What amp settings do you need for Iron Maiden?
On a generic five-knob amp, The Trooper and Fear of the Dark both start at Gain 7, Bass 6, Middle 6, Treble 6, Presence 5, Reverb 1: a starting point follows the style of the part, and these share one. These are starting points, not the settings used on the records.
What gear did Iron Maiden use on these songs?
The Trooper: Ex-Paul Kossoff black Stratocaster (Murray), SG or Ibanez Destroyer (Smith); 50-watt Marshalls (the players' 1983 rigs). Fear of the Dark: Fender Stratocasters, both players' guitar of choice (not placed on this song); Marshall, Murray's amp outside 1986 to 1988 (not placed on this song). Each song page lists the sources behind its rig.
Can you get the Iron Maiden tone without the original gear?
Yes. What carries these sounds is the gain structure, the EQ curve, the pickup position and the order of the effects, and all four can be rebuilt on other equipment. Tonelify rewrites each starting point for the amp and guitar you own.
