Given this paragraph about grunge guitarists, what types of amplifiers would typically be preferred?

Context: Grunge is generally characterized by a sludgy electric guitar sound with a thick middle register and rolled-off treble tone and a high level of distortion and fuzz, typically created with small 1970s-style stompbox pedals, with some guitarists chaining several fuzz pedals together and plugging them into a tube amplifier and speaker cabinet.Grunge guitarists use very loud Marshall guitar amplifiers and some used powerful Mesa-Boogie amplifiers, including Kurt Cobain and Dave Grohl. Grunge has been called the rock genre with the most "lugubrious sound"; the use of heavy distortion and loud amps has been compared to a massive "buildup of sonic fog" or even dismissed as "noise" by one critic.As with metal and punk, a key part of grunge's sound is very distorted power chords played on the electric guitar.

Answer: Some grunge guitarists use loud Marshall or Mesa-Boogie amplifiers.
