Best Amps for Heavy Metal
Metal amp tone is built around tightness under gain — a good metal amp stays articulate and controlled even with the gain dimed, where a lesser amp turns to indistinct mush. Two amps define the genre more than any others.
Peavey 5150 / 6505 — The Genre Standard
Co-designed with Eddie Van Halen and now inseparable from thrash, metalcore, and modern high-gain metal generally, the Peavey 5150/6505 (~£800-1,200) delivers a tight, aggressive, mid-forward high-gain tone that cuts through a dense mix without needing heavy EQ correction. It has appeared on more metal records of the last 30 years than any other single amp.
Mesa/Boogie Dual Rectifier — Heavier and More Saturated
The Dual Rectifier (~£1,800-2,500) offers a thicker, more compressed, heavier-feeling gain structure — the choice in more technical death metal and doom where maximum saturation matters more than the 6505's cutting attack.
Budget Alternative: Boss Katana
The Boss Katana 100 MkII (~£350) has a dedicated "Brown" channel voiced to approximate high-gain American tube tone, and it's genuinely capable at bedroom-to-small-gig volume without needing a cabinet or mic'ing setup.
Practical Notes
Wattage: 50W is plenty for loud stage use; 100W buys clean headroom that matters less for a genre built on saturation.
Attenuators: Usable but noticeably reduce a speaker's impact — moderate volume through a full cabinet generally beats maximum gain through an attenuated one.
FAQ
What is the most popular metal amp ever? The Peavey 5150/6505 — used on more metalcore, death metal and thrash records than any other amp.
Is 100W necessary for metal? No — 50W is sufficient for loud stage use. 100W gives more clean headroom before distortion, which is less relevant for high-gain use.
Can I use an attenuator with a metal amp? Yes — but attenuators reduce the speaker's impact significantly. High-gain through an attenuated cab sounds less impressive than moderate-volume through a full cab.
What is the best metal amp under £1,000? Peavey 6505+ 112 combo (£800) or Boss Katana 100 MkII (£350). The Katana's Brown channel is excellent for high-gain on a budget.
