Passage: Bryant identified "Son of Three" as an example of "when the Breeders set out to rock", noting "the chugging guitars and stomping drums." The Breeders re-recorded "Son of Three" in July 2002 for its release as Title TK's third single; this version is faster than the album track, and reflects the speed they were playing the song in concert that year. The lyrics of both "Son of Three" and "The She" suggest extended road trips with unknown outcomes. The album's next song, "Put on a Side", has a distinctive bassline and a cramped, repressive feel. Berger wrote that Kim Deal's "voice grinds sweetly, weariedly, sloppily inside your brain," as she repeats twelve words over the course of the song: "Better I better I stayed up / Better mono, put on a side."An earlier version of "Full on Idle", Title TK's eighth track, was released on the Amps' Pacer in 1995. In a 1997 interview, Deal expressed an interest in redoing multiple Amps songs, partially because she did not feel Pacer was well recorded. Bryant opined that both versions of "Full on Idle" sound almost the same, but The Village Voice's Jessica Grose wrote that the Breeders' rendition is noticeably slower. In Cibula's view, this version contains elements of country music, cumbia, and ska. The Guardian's Betty Clarke cited the line "Obey your colorist, bleach it all away" as an example of Title TK's amusing, off-center lyrics. On "Sinister Foxx", Deal repeatedly sings "Has anyone seen the iguana?" She has explained this as being a reference to buying marijuana: "Have you ever bought a bag of weed? You walk in, and the pot dealer's got an empty terrarium ... Every time I go to a pot dealer's house, there's no iguana." Another line, "I'm in beer class every Thursday night", refers to the alcohol awareness classes that Richard Presley attended after being caught driving while drunk. Phares described the song as having a "sexy menace", and Berger compared the drum part to gunshots and door-knocking.Moores identified in "Forced to Drive" the "quiet-LOUD-quiet" dynamic for which Deal's former band, the Pixies, are famous. Berger noticed a similar contrast between the song's "pop verses" and "the gloom of a twisty, malignant chorus". For Abbott, this four-chord chorus "approaches exuberance" in its mixture of catchy melody and grunge. The penultimate track, "T and T", was described by Bryant as an instrumental introduction leading into "Huffer". Kelley Deal has stated that these two songs share a thematic union: the latter is about the negative side of inhaling paint or other substances, while the former stands for "Toil and Trouble", also about the hardships that inhaling chemicals can cause. "Huffer" is, according to Moores, a lively, poppy track, and critics have commented on its "da-da-da" and "ah-ah" chorus. 
Question: What was the name of the song that had a reference to buying marijuana in it?
Sinister Foxx.

Passage: 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 (the latter in early, grunge-oriented Foo Fighters songs ). 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.Whereas metal guitarists' overdriven sound generally comes from a combination of overdriven amplifiers and distortion pedals, grunge guitarists typically got all of their "dirty" sound from overdrive and fuzz pedals, with the amp just used to make the sound louder. Grunge guitarists tended to use the Fender Twin Reverb and the Fender Champion 100 combo amps (Cobain used both of these amps). The use of pedals by grunge guitarists was a move away from the expensive, studio-grade rackmount effects units used in other rock genres. The positive way that grunge bands viewed stompbox pedals can be seen in Mudhoney's use of the name of two overdrive pedals, the Univox Super-Fuzz and the Big Muff, in the title of their "debut EP Superfuzz Bigmuff".  In the song Mudride, the band's guitars were said to have "growled malevolently" through its "Cro-magnon slog". 
Question: What two brands of amplifiers do grunge guitarists use?

Marshall.
