[Q]: 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, Husker Du, 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 ?

input: Please answer the following: This article: At the court in Ferrara, a collection of ladies skilled in music inspired the composer Luzzasco Luzzaschi and caught the Duke's interest. This group, which led to the formation of the concerto delle donne, performed within the context of the Duke's musica secreta, a regular series of chamber music concerts performed for an exclusive audience. This preliminary group was originally made up of talented but amateur members of the court: the sisters Lucrezia and Isabella Bendidio, Leonora Sanvitale, and Vittoria Bentivoglio. They were joined by bass Giulio Cesare Brancaccio, who was specifically brought to the court in 1577 for his singing ability. The preliminary ensemble was active throughout the 1570s, and its membership solidified in 1577. Only later did professionals replace these original singers. The Duke did not announce the creation of a professional, all-female ensemble; instead, the group infiltrated and gradually dominated the musica secreta, so that after the dismissal of Brancaccio for insubordination in 1583, no more male members of the musica secreta were hired. Even when Brancaccio was performing with the consort it was referred to as a ladies' ensemble, because women singing together was the most exciting aspect of the group. This new ensemble, the concerto delle donne, was created by Alfonso in part to amuse his young new wife, Margherita Gonzaga d'Este (she was only fourteen when they wed in 1579), and in part to help the Duke achieve his artistic goals for the court. According to Grana, a contemporary correspondent, "Signora Machiavella [Lucrezia], Signora Isabella, and Signora Vittoria have abandoned the field, having lost the backing of Luzzaschi". The first recorded performance by the professional ladies was on November 20, 1580; by carnival season in 1581, they were performing together regularly.This new "consort of ladies" was viewed as an extraordinary and novel phenomenon; most witnesses did not connect the second period of the concerto delle donne with the group of ladies who sang in... contains an answer for the question: What were the first names of the two sisters in the original preliminary group?, what is it ?

Problem: This article: In 2004, the Loyalsock Creek Watershed Association installed a fence on the creek's banks near the cabins to limit pedestrian access and erosion. The association planted shrubs and trees in the same area to stabilize the creek's banks in 2008, and in September 2010 replaced more than 1,500 feet (460 m) of fence with a less visible version. On January 25, 2010 flooding caused by heavy rain and melt from 20 inches (510 mm) of snow "washed out a bridge" leading to the cabin area and destroyed 86 feet (26 m) of road there, leaving the park looking like "the set of disaster movie". The cabin area road needed $72,120 in repairs, the park was not fully restored until Memorial Day. Two floods hit the park in 2011, the first from Hurricane Irene on August 29, and the second from Tropical Storm Lee on September 8. Lee washed away about 20 to 22 short tons (18 to 20 t) of gravel used to make emergency repairs to roads in the park from Irene damage. Loyalsock Creek reached 20.4 feet (6.2 m) south of the park, and campers in the park had to be evacuated. Worlds End and Promised Land State Park had "significant damage to roads and bridges", damage to Loylasock State Forest roads was also heavy, and the DCNR estimated the two storms caused $3 to $4 million of damage to its forests and parks. Worlds End was closed for two weeks after the Lee flood.As of 2012, post-war facilities include the park office, five wash-houses and other modern restroom facilities, beach house with concession stand, chapel, amphitheater, and modern camping areas. Worlds End State Park is one of twenty-one chosen by the Pennsylvania Bureau of Parks for its "Twenty Must-See Pennsylvania State Parks" list. The DCNR describes it as "[v]irtually in a class by itself, this wild, rugged and rustic area seems almost untamed". It goes on to praise the opportunities for camping and hiking at the park, and its scenery and vistas. contains an answer for the question: What does the DCNR describe as "[v]irtually in a class by itself"?, what is it ?
