Best Guitar Amp for Metal: Unleashing High-Gain Fury

Guitar amplifiers are essential tools for musicians aiming to project their sound with clarity and power, particularly within the metal genre, which is known for its heavy riffs and high-gain distortion. The best guitar amp for metal can elevate your tone, delivering the aggressive soundscapes that define the genre. Metal musicians often rely on amplifiers that can produce intense volume and sustain without losing definition or succumbing to unwanted noise.

When it comes to selecting the best guitar amp for metal, several key features are paramount. High gain capabilities are crucial as they allow the amp to produce the iconic thick, compressed tone associated with metal music. Durability and reliability must also be considered, since metal guitarists frequently perform at high volumes and require equipment that can withstand rigorous use. Equalization controls are important as well to sculpt and refine the amp’s sonic output, tailoring it to the specific nuances of the subgenre played—be it thrash, death metal, or progressive metal.

Equally important is considering the amp’s responsiveness to effects pedals, as many metal guitarists use an array of pedals to shape their unique sounds. Some amplifiers integrate better with pedals than others, and choosing an amp that complements your existing pedal setup is crucial. Lastly, the size and portability may be significant factors depending on whether the amp is for studio, practice, or live performance use.

In our extensive search to guide you to the perfect sound, we have rigorously tested and analyzed numerous guitar amps tailored for metal music. We have looked for those that deliver not just the power and gain required, but also the versatility and durability to become a mainstay in any metal guitarist’s rig.

Blackstar FLY3 Mini Amp

Blackstar Electric Guitar Mini Amplifier fly3

We recommend this amp if you’re looking for a highly portable, versatile option that doesn’t compromise on metal tones.


  • Immense sound in a small package
  • Innovative features like the ISF and tape delay

One aspect we can’t ignore is the 3 Watt power output. While admirable for its size, it does limit the FLY3’s use in larger spaces or with a full band.

Nonetheless, metal enthusiasts seeking a compact practice amp with real grunt, the Blackstar FLY3 Mini Amp is a prime choice. It’s a no-brainer for warm-up sessions, hotel room practice, or simply kicking back with some tracks after a show.

Buying Guide

When we are in the market for a guitar amp specifically tailored to metal, we need to consider several critical factors that reflect on the amp’s performance and our requirements.

Power and Size

It’s imperative to assess the wattage an amp delivers. Generally, for practice sessions, amps with lower wattage are sufficient. Conversely, live performances demand more powerful amps.

  • Practice: 10-30 watts
  • Gigs: 50+ watts

Amplifier Types

We distinguish between solid-state, tube, and digital modeling amplifiers. Solid-state amps are reliable and require less maintenance, while tube amps are known for their superior tone quality. Digital modeling amps offer a variety of sounds and effects.

Sound Customization

We look for amps that allow extensive sound customization. Equalizers with multiple bands and built-in effects such as reverb and delay can significantly enhance the sound.

EQ Bands:

Additional Features

  • Built-in Effects: Most beneficial for experimenting with sound.
  • Speakers: The right speaker size (usually 12 inches for metal) greatly affects the quality of output.

Choosing our ideal metal guitar amp requires careful consideration of these aspects. Our focus should always be on the combination of features that best suit our unique style and playing needs.
