Some context: Carlos Santana  audio  (born July 20, 1947) is a Mexican and American musician who first became famous in the late 1960s and early 1970s with his band, Santana, which pioneered a fusion of rock and Latin American jazz. The band's sound featured his melodic, blues-based guitar lines set against Latin and African rhythms featuring percussion instruments such as timbales and congas not generally heard in rock music. Santana continued to work in these forms over the following decades. He experienced a resurgence of popularity and critical acclaim in the late 1990s.
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.

Some context: John Herbert Gleason was born in 1916 at 364 Chauncey Street in the Bedford-Stuyvesant section of Brooklyn. Named Herbert Walton Gleason, Jr., at birth, he was baptized John Herbert Gleason, and  grew up at 328 Chauncey (an address he later used for Ralph and Alice Kramden on The Honeymooners). His parents were Herbert Walton "Herb" Gleason, an Irish-American insurance auditor, and Mae "Maisie" (nee Kelly), originally of Farranree, Cork, Ireland. Gleason was one of two children; his brother Clement J. died of meningitis at age 14.
Gleason did two Jackie Gleason Show specials for CBS after giving up his regular show in the 1970s, including Honeymooners segments and a Reginald Van Gleason III sketch in which the gregarious millionaire was portrayed as an alcoholic. When the CBS deal expired, Gleason signed with NBC. He later did a series of Honeymooners specials for ABC. Gleason hosted four ABC specials during the mid-1970s. Gleason and Carney also made a television movie, Izzy and Moe (1985), about an unusual pair of historic Federal prohibition agents in New York City who achieved an unbeatable arrest record with highly successful techniques including impersonsations and humor, which aired on CBS in 1985.  In April 1974, Gleason revived several of his classic characters (including Ralph Kramden, Joe the Bartender and Reginald Van Gleason III) in a television special with Julie Andrews. In a song-and-dance routine, the two performed "Take Me Along" from Gleason's Broadway musical.  In 1985, three decades after the "Classic 39" began filming, Gleason revealed he had carefully preserved kinescopes of his live 1950s programs in a vault for future use (including Honeymooners sketches with Pert Kelton as Alice). These "lost episodes" (as they came to be called) were initially previewed at the Museum of Television and Radio in New York City, aired on the Showtime cable network in 1985, and later added to the Honeymooners syndication package. Some of them include earlier versions of plot lines later used in the 'classic 39' episodes. One (a Christmas episode duplicated several years later with Meadows as Alice) had all Gleason's best-known characters (Ralph Kramden, the Poor Soul, Rudy the Repairman, Reginald Van Gleason, Fenwick Babbitt and Joe the Bartender) featured in and out of the Kramden apartment. The storyline involved a wild Christmas party hosted by Reginald Van Gleason up the block from the Kramdens' building at Joe the Bartender's place.
