This article: Other key pedals used by grunge bands included four brands of distortion pedals (the Big Muff, DOD and BOSS DS-2 and BOSS DS-1 distortion pedals) and the Small Clone chorus effect, used by Kurt Cobain on "Come As You Are" and by the Screaming Trees on "Nearly Lost You". The RAT distortion pedal played a key role in Cobain's switching from quiet to loud and back to quiet approach to songwriting. The use of small pedals by grunge guitarists helped to start off the revival of interest in boutique, hand-soldered, 1970s-style analog pedals. The other effect that grunge guitarists used was one of the most low-tech effects devices, the wah-wah pedal. Both "[Kim] Thayil and Alice in Chains' Jerry Cantrell ... were great advocates of the wah wah pedal." Wah was also used by the Screaming Trees, Pearl Jam, Soundgarden, Mudhoney and Dinosaur Jr.Grunge guitarists played loud, with Kurt Cobain's early guitar sound coming from an unusual set-up of four 800 watt PA system power amplifiers. Guitar feedback effects, in which a highly amplified electric guitar is held in front of its speaker, were used to create high-pitched, sustained sounds that are not possible with regular guitar technique. Grunge guitarists were influenced by the raw, primitive sound of punk, and they favored "... energy and lack of finesse over technique and precision"; key guitar influences included the Sex Pistols, The Dead Boys, Celtic Frost, Voivod, Neil Young (Rust Never Sleeps, side two), The Replacements, Hüsker Dü, Black Flag and The Melvins. Grunge guitarists often downtuned their instruments for a lower, heavier sound. Soundgarden's guitarist, Kim Thayil, did not use a regular guitar amplifier; instead, he used a bass combo amp equipped with a 15-inch speaker as he played low riffs, and the bass amp gave him a deeper tone. contains an answer for the question: What is the full name of the person who used a bass combo amp equipped with a 15-inch speaker?, what is it ?
