Which is from farther west, The Commuters or Amplifier?
Amplifier (band) Amplifier are an English rock band originating from Manchester. The band has released six albums and four EPs since its inception in 1999. Their music has been described as "Soundgarden, Tool, Black Sabbath, Oceansize and Pink Floyd taking copious amounts of mind-altering substances and venturing on a trip through time and space (to another dimension), and back again." Their music is characterised by guitarist Sel Balamir's effect pedals, Matt Brobin's complex drumming, extended heavy sections, atmospheric compositions and philosophical lyrics.
Guitar speaker A guitar speaker is a loudspeaker – specifically the driver (transducer) part – designed for use in a combination guitar amplifier (in which a loudspeaker and an amplifier are installed in a wooden cabinet) of an electric guitar, or for use in a guitar speaker cabinet. Typically these drivers produce only the frequency range relevant to electric guitars, which is similar to a regular woofer type driver, which is approximately 75 Hz — 5 kHz, or for electric bass speakers, down to 41 Hz  for regular four-string basses or down to about 30 Hz for five-string instruments.
