input: Carlos Santana's distinctive guitar tone is produced by PRS Santana signature guitars plugged into multiple amplifiers. The amps consist of a Mesa Boogie Mark I, Dumble Overdrive Reverb and more recently a Bludotone amplifier. Santana compares the tonal qualities of each amplifier to that of a singer producing head/nasal tones, chest tones, and belly tones. A three-way amp switcher is employed on Carlos's pedal board to enable him to switch between amps. Often the unique tones of each amplifier are blended together, complementing each other producing a richer tone.  He also put the "Boogie" in Mesa Boogie. Santana is credited with coining the popular Mesa amplifier name when he tried one and exclaimed, "That little thing really Boogies!"  Specifically, Santana combines a Mesa/Boogie Mark I head running through a Boogie cabinet with Altec 417-8H (or recently JBL E120s) speakers, and a Dumble Overdrive Reverb and/or a Dumble Overdrive Special running through a Brown or Marshall 4x12 cabinet with Celestion G12M "Greenback" speakers, depending on the desired sound. Shure KSM-32 microphones are used to pick up the sound, going to the PA. Additionally, a Fender Cyber-Twin Amp is mostly used at home.  During his early career Santana used a GMT transistor amplifier stack and a silverface Fender Twin. The GMT 226A rig was used at the Woodstock concert as well as during recording Santana's debut album. During this era Santana had also begun to use the Fender Twin, which was also used on the debut and proceedingly at the recording sessions of Abraxas.

input: Yagan's head was initially taken to Henry Bull's house. Moore saw it there and sketched the head a number of times in his unpublished, handwritten diary, commenting that "possibly it may yet figure in some museum at home." The head was preserved by smoking.  In September 1833, Governor Irwin sailed for London, partly to give his own account of the events leading up to the killing. This was an unusual measure, especially given his regiment was about to leave for a tour of duty in India. The Colonial Office indicated satisfaction with Irwin's administration of the colony.  Travelling with Irwin was Ensign Robert Dale, who had somehow acquired Yagan's head. According to the historian Paul Turnbull, Dale appears to have persuaded Irwin to let him have the head as an "anthropological curiosity". After arriving in London, Dale tried to sell the head to scientists, approaching a number of anatomists and phrenologists. His price of L20 failed to find a buyer, so he made an agreement with Thomas Pettigrew for the exclusive use of the head for 18 months. Pettigrew, a surgeon and antiquarian, was well known in the London social scene for holding private parties at which he unrolled and autopsied Egyptian mummies. He displayed the head on a table in front of a panoramic view of King George Sound reproduced from Dale's sketches. For effect, the head was adorned with a fresh corded headband and feathers of the red-tailed black cockatoo.  Pettigrew had the head examined by a phrenologist. Examination was considered difficult because of the large fracture across the back of the head caused by the gunshot. His conclusions were consistent with contemporary European opinion of Indigenous Australians. Dale published these in a pamphlet entitled Descriptive Account of the Panoramic View &c. of King George's Sound and the Adjacent Country, which Pettigrew encouraged his guests to buy as a souvenir of their evening. The frontispiece of the pamphlet was a hand-coloured aquatint print of Yagan's head by the artist George Cruikshank.  Early in October 1835, Yagan's head and the panoramic view were returned to Dale, then living in Liverpool. On 12 October he presented them to the Liverpool Royal Institution, where the head may have been displayed in a case along with some other preserved heads and wax models illustrating cranial anatomy. In 1894 the Institution's collections were dispersed, and Yagan's head was lent to the Liverpool Museum; it is thought not to have been put on display there. By the 1960s Yagan's head was badly deteriorated. In April 1964 the museum decided to dispose of it. It arranged burial of the head on 10 April 1964, together with a Peruvian mummy and a Maori head. They were buried in Everton Cemetery's General Section 16, grave number 296. In later years a number of burials were made around the grave. For example, in 1968 a local hospital buried directly over the box, 20 stillborn babies and two infants who died soon after birth.

input: In the fall of 1943, the PPR leadership began discussing the creation of a Polish quasi-parliamentary, communist-led body, to be named the State National Council (Krajowa Rada Narodowa, KRN). After the Battle of Kursk the expectation was of a Soviet victory and liberation of Poland and the PPR wanted to be ready to assume power. Gomulka came up with the idea of a national council and imposed his point of view on the rest of the leadership. The PPR intended to obtain consent from the Cominterm leader and their Soviet contact Georgi Dimitrov. However, in November the Gestapo arrested Finder and Malgorzata Fornalska, who possessed the secret codes for communication with Moscow and the Soviet response remained unknown. In the absence of Finder, on 23 November Gomulka was elected general secretary (chief) of the PPR and Bierut joined the three-person inner leadership.  The founding meeting of the State National Council took place in the late evening of 31 December 1943. The new body's chairman Bierut was becoming Gomulka's main rival. In mid-January 1944 Dimitrov was finally informed of the KRN's existence, which surprised both him and the Polish communist leaders in Moscow, increasingly led by Jakub Berman, who had other, competing ideas concerning the establishment of a Polish communist ruling party and government.  Gomulka felt that the Polish communists in occupied Poland had a better understanding of Polish realities than their brethren in Moscow and that the State National Council should determine the shape of the future executive government of Poland. Nevertheless, to gain a Soviet approval and to clear any misunderstandings a KRN delegation left Warsaw in mid-March heading for Moscow, where it arrived two months later. By that time Stalin concluded that the existence of the KRN was a positive development and the Poles arriving from Warsaw were received and greeted by him and other Soviet dignitaries. The Union of Polish Patriots and the Central Bureau of Polish Communists in Moscow were now under pressure to recognize the primacy of the PPR, the KRN and Wladyslaw Gomulka, which they ultimately did only in mid-July.  On 20 July, the Soviet forces under Marshal Konstantin Rokossovsky forced their way across the Bug River and on that same day the combined meeting of Polish communists from the Moscow and Warsaw factions finalized the arrangements regarding the establishment (on 21 July) of the Polish Committee of National Liberation (PKWN), a temporary government headed by Edward Osobka-Morawski, a socialist allied with the communists. Gomulka and other PPR leaders left Warsaw and headed for the Soviet-controlled territory, arriving in Lublin on 1 August, the day the Warsaw Uprising erupted in the Polish capital.
