subject: Heavy Metal And Hard Rock Amplifiers [print this page] Companies such as Marshall prefer to use 12 speakers in a closed-back cabinet in contrast to "tweed"-style amplifiers that tend to use speakers set in an open-backed cabinet. These guitar amplifiers usually let users switch between "clean" and distorted tones (or a "crunch" tone for the rhythm guitar, and "lead" tone) by means of a foot-operated switch.
