About Holy Wars


Few Thrash Metal tracks demand as much from a guitarist as "Holy Wars." The opening riff is the first real test: a low, aggressive figure in Eb Standard that sits in E minor and relies on tight palm muting and precise alternate picking to land with the right punch. At 120 BPM the riff feels manageable at first glance, but the song shifts between complex rhythm passages and fast lead runs frequently enough that stamina becomes a genuine concern. Dave Mustaine's rhythm work throughout is as technically demanding as the solos, so don't rush past it to get to the lead sections. The transition points between the song's distinct movements are where most players lose their footing, so isolating those on the Practice Toolbar and looping them slowed down is the most efficient way to get them clean. Megadeth built this track as essentially two songs stitched together, which means you are really learning multiple distinct guitar parts under one title.

  • The song is played in Eb Standard tuning, so drop your whole guitar a half step before you start working through the riffs.
  • The opening palm-muted riff requires strict alternate picking at a steady 120 BPM, and any tension in your pick hand will cause it to fall apart quickly.
  • Because the song shifts through several distinct sections with different feels and tempos, looping each section separately in the Practice Toolbar is far more effective than running the whole track.

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
Pedal

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
Pedal

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.
