About Holy Wars


Few thrash tracks demand as much from a rhythm guitarist as "Holy Wars." Megadeth tune down to Eb Standard, which loosens the strings just enough to give the heavy riffing a thicker, slightly darker feel without shifting the written key. The song sits in E minor at 120 BPM, and the opening riff alone covers a lot of ground: rapid alternate picking, string skipping, and quick positional shifts that catch beginners off guard. The real challenge is maintaining clean note separation at speed while keeping the aggressive tone tight. The mid-song clean interlude is a contrast worth practicing carefully too, since the jump back into the heavy sections requires instant right-hand aggression. Use the Practice Toolbar to isolate the trickiest picking passages and loop them slowed down until the fretting hand can keep up without tension. This is a strong workout in Thrash Metal picking mechanics and left-hand accuracy across the entire neck.

  • The song is played in Eb Standard tuning, dropping every string by a half step to add low-end weight to the heavy riffing.
  • The opening riff combines rapid alternate picking with string skipping, making clean note separation the primary technical hurdle to overcome.
  • A contrasting clean-guitar interlude sits mid-song, so players need to practise the sudden dynamic shift back into full-speed heavy picking.

How to Play Holy Wars

Tuning: Eb Standard · Key: E minor · Tempo: 120 BPM

It is played in Eb standard, a half step down, so tune down before you start or every position and bend will sit a half step sharp against the recording.

Use the section loop to isolate a passage, drop the speed below 100%, and set the metronome to 120 BPM to build it up to tempo.

Gibson Flying V
Guitar

Gibson Flying V

Dave Mustaine's current signature Flying V delivers the V-shaped body geometry essential for accessing upper frets on his complex spider-chord voicings and fast lead lines. The guitar's thin, fast neck profile and fixed bridge provide the tuning stability and articulation Megadeth's precise, aggressive riffing demands.

Marshall JCM800
Amp

Marshall JCM800

Mustaine built Megadeth's signature razor-sharp, scooped-mid tone on Marshall JCM800s, with gain around 7-8 to retain pick dynamics and articulation under heavy palm-muting. The amp's responsive tube saturation transforms hot pickups into the controlled, fast low-end aggression that defines thrash metal rhythm tones.

DigiTech Whammy

Marty Friedman used the Digitech Whammy as a lead accent tool, adding pitch-shifting texture to solos without cluttering Megadeth's minimalist effects philosophy. The pedal's harmonic richness complemented his warm, vocal-like Seymour Duncan humbucker tone during the band's classic era.

ISP Decimator Noise Gate

ISP Decimator Noise Gate

The ISP Decimator is essential for Mustaine's high-gain thrash setup, eliminating feedback and noise between palm-muted riffs without compromising sustain. This noise gate allows him to push the Marshall into aggressive saturation while maintaining the tight, articulate attack Megadeth's complex rhythms require.
