30-458: During 1952, the Fender 5B6 Bassman amplifier was introduced as a combo amplifier cabinet that included the amplifier chassis combined with one 15" speaker. The 1952–1954 5B6 Bassman amplifiers had two 6SC7 or 6SL7GT pre-amp tubes, two 5881 power tubes and a single 5U4G rectifier tube. It was designed to generate 26 watts at an 8-ohm impedance load, and offered a cathode-based bias. From 1952 through

60-421: A solid-state rectifier unit. Later on, production was moved to Ensenada, Baja California , and the model name was altered to "59 Bassman LTD". The LTD came equipped with the original 5AR4 rectifier tube, and four Jensen P10R reissue alnico speakers, which was period correct for the original amp. In late 1960, Fender introduced a completely redesigned model 6G6 Bassman Amp, using the "piggy-back" design, in which

90-486: A modification within the Presence control circuit. During early 1960, Fender began producing the 5F6-A Bassman with Jensen P10Q speakers. The P10Q speakers handle more power and produce better "clean" tones than the earlier P10R speakers. The P10R speakers were shipped within all Fender Bassman amps from late 1954 until early 1960. Many professional music industry analysts have proclaimed the 1950s Fender 4×10 Bassman amps as

120-502: A range of solid-state Fender Bassman combos, the Bassman 25, 60, and 200. These were joined by the Bassman 100 combo and the tube-powered Bassman 300 head in 2002. In 2005 all the solid-state combos were replaced with much smaller and lighter, and more powerful models, the Bassman 100, 150, and 250. The Bassman 250 was available with two speaker combinations or as a head only. These solid-state Bassman amps were discontinued in 2010, however

150-473: A reference book of 1930s RCA commercial loudspeaker designs. Soon a business partnership to sell these amps had formed between Traynor and Jack Long, the man who owned the music store that Traynor worked at. The company was named Yorkville Sound . In 1964, the Dynabass became the "Bass Master", model "YBA-1", and its associated 15-inch speaker cabinet became the "YS-15". The YBA-1 "Bass Master" circuit

180-608: A wide range of electric, acoustic, and bass guitar amps. In 1963 Traynor amps were designed by Peter Traynor, a music shop ( Long & McQuade ) repairman who had been customizing amplifiers as a way to save costs for the business. Through experimentation and experience, Traynor developed a bass guitar amplifier that he called the Traynor Dynabass. By the end of 1963, Traynor was selling the Dynabass amps along with matching 15-inch speaker cabinets, as well as Traynor portable columnar public address (PA) speakers based on

210-401: A wider swath of grill cloth. Fender ceased production of 5B6 Bassman amplifiers during the spring of 1954. During November 1954, Fender introduced the newly designed 5D6 Bassman amplifier offering four 10" speakers and was designed utilizing two rectifier tubes. The 5D6 was a major departure from the earlier 5B6 Fender Bassman model. Designed by Freddie Tavares , longtime R&D man at Fender,

240-426: Is 0013 (Frank Roy), 0035 (Albert Talley), 0075 (Jim Cornett), 0077 (Perry Tate), 0089 (Mark Grandfield), 0701, 0745 (Walter Horton), 0769 (Hayes Kolb), 0780 (sold on eBay Nov 2006), 0783, and 0785 (Hayes Kolb) are among those still known to exist. Fender began making other models with tweed covering, a similar open backed cabinet with a rectangular grill cloth and a narrow (just over an inch wide) tweed covered panel at

270-513: Is a brand of bass amplifiers and guitar amplifiers , the first brand formed by Yorkville Sound . The Traynor brand, named for founder Peter Traynor , began in 1963 with the Dynabass bass amplifier, a rental product. Traynor first became popular in Canada by providing less expensive versions of the circuits used in Marshall and Fender amplifiers of the time. The revived brand now produces

300-528: Is very similar to the Fender Bassman , which in turn inspired the classic Marshall 1959 "Plexi" amplifier. The column loudspeakers were designated "YSC-1" and two additional models were created: the "YSC-2" with fewer, larger drivers to obtain more low-frequency bass extension and the "YSC-3" which was a cut-down version of the YSC-1 for customers who needed a smaller loudspeaker. Starting in 1965 with

330-436: The "Silverface" model was introduced in mid 1967. Early "Drip-Edge" Silverface Bassmans made in mid 1967 used the same AB165 circuitry as the previous Blackface versions. The Brownface, Blackface, and Silverface "piggyback head" (except the Bassman 10 and 20, which were also combo amplifiers) versions of the 1960s, 1970s, and early 1980s generally followed a trend toward cleaner sound and more headroom. In 2000, Fender introduced

360-510: The "headroom" or clean power output capability of the amplifier. Similar preamp changes were also incorporated in the 5F8 Twin Amp at about the same time, but not on other large-size Fender amps. During 1958, Fender introduced the model 5F6-A Bassman model. This final 1950s Tweed Bassman model product line included a change from the 83 mercury vapor rectifier tube to the GZ34 rectifier tube, as well as

390-453: The 5E6 series had been sold. In July 1957, Fender introduced the model 5F6 Bassman. This model also had four Jensen P10R speakers, but the power supply was redesigned around a single 83 mercury vapor rectifier tube, and a new preamp circuit was introduced that included a three-knob tone stack , with separate controls for treble, midrange and bass. The power amp included a "long tailed pair" phase inverter, an innovation that noticeably increased

420-527: The Traynor Hi-Tone, a 2x12 test guitar amp (of which only two were ever made) Pete Traynor began experimenting with guitar amp designs. The YGA-1 (a 45 watt amp head) and the YGM-1 (a 1x12 20 watt tube combo) were the first products of this research. Full production of these amps began in 1966, and the release of new models continued until the 70s. In 1970, Traynor introduced the new Traynor logo (in

450-715: The Traynor brand in with the YCV40 (Custom Valve) model. The brand has a wide product range including DynaGain solid state guitar amplifiers, International amplifiers, Bass Master bass amplifiers, Keyboard amplifiers and an acoustic guitar amplifier line. This line of solid state amplifiers are inexpensive foreign manufactured solid state amps, though the TVM10 is the sole battery-operated amplifier offered by Traynor. This line of solid state amplifiers with tube emulation provides analog-based amplification with special circuitry to emulate

480-415: The amplifier chassis is housed in a small cabinet, attached by metal clips to a larger separate speaker enclosure. The early models were called "Brownface" because of the dark brown color used on the control panel. The 6G6 model was covered in rough Blonde colored Tolex material with Oxblood colored grill cloth. It had a single GZ34 rectifier, two 5881/6L6GC power tubes and four 12AX7 preamp tubes. The output

510-518: The beginning of every Warner Bros. Looney Tunes theatrical short was played by Tavares. His other credits include work with Ray Conniff , Bing Crosby , Elvis Presley , Dean Martin , The Sons of the Pioneers , "Tennessee" Ernie Ford , Spike Jones and His City Slickers, Lawrence Welk , and Henry Mancini . While he worked with Leo Fender and others in the design of the Stratocaster ,

540-462: The circuit unmodified in their JTM45 amplifier during the early 1960s. The early version of Traynor YBA-1 is also directly copied from 5F6-A circuits, with later versions modified. In 1990, Fender began reissuing the 5F6-A Bassman as guitar amp. The first series of the reissue were made at the Corona, California facility, and came equipped with four Eminence-made 10" blue frame AlNiCo speakers, and

570-592: The flat cast tin Fender with the brown paint in the tail, to a plastic logo with faux chrome and more 3-D shape. In 1964 Fender introduced the AA864 circuit, and changed the appearance to the "Blackface" design, with black tolex covering and a black painted control panel. Fender was sold to CBS in 1965, and the AA165 circuit was briefly introduced, before being replaced by the AB165 circuit. The "Blackface" design continued until

600-698: The general consensus is that his most significant contribution to the development of that instrument was his role the design of the vibrato system. He is credited as one of the designers of both the Stratocaster guitar and Bassman amp by the Museum of Modern Art in New York. He died 24 July 1990 in California at age 77.

630-447: The greatest guitar amp ever. The first 1954 Fender Tweed 5D6 4×10 circuit generated further Tweed Bassman amplifier development through 1960. Several Bassman models were progressively influenced by the 5D6 through the last Fender Tweed 5F6-A Bassman's circuit design. The 5F6-A Bassman's design is greatly influential in terms of guitar amplication, as the schematic was directly copied by other manufacturers. Marshall Amplification utilized

660-487: The new circuit included two rectifier tubes and became known as the Dual Rectifier Bassman. Instead of the single 15" speaker, four 10" Jensen Alnico P10R speakers were used. The circuit had two innovations: a fixed bias for the power tubes, which increased power in comparison to the earlier cathode bias design, and a cathodyne phase inverter, using half of the 12AX7 tube and allowing a third gain stage on

690-457: The other half. The first 4x10 Bassman amplifiers started with a batch of prototypes in November and December 1954, model 5D6. No schematic for the 5D6 circuit has ever been found, but Ken Fox and Frank Roy have created a few from originals, and copies are freely available online. Only 11 of these early 5D6 Bassman examples are known to have survived. The lowest serial number known to still exist

720-461: The shape of a parallelogram) that was less prone to having the initial 'T' and final 'r' break off to become "rayno". In 1976, Peter Traynor left Yorkville Sound, suffering from a bad back. The Traynor brand would be slowly phased out over the next 17 years until its reintroduction in 2000. In 2011, Traynor products are manufactured in Pickering, Ontario. In 2000, Yorkville Sound reintroduced

750-425: The spring of 1954, Fender produced approximately 660 model 5B6 Bassman amplifiers (serial numbers #0001–0660). The earlier cabinets have been called "TV Front" designs, with a front panel that had a rectangular grill cloth with rounded corners and looked much like a television of that era. In 1953 the cabinet designs were changed to the so-called "Wide Panel" design, with a 5-inch-wide tweed-covered panel above and below

780-434: The top and bottom. Produced from 1954 until 1960, these models are called the "narrow panel" tweed amps . Fender introduced the model 5D6 "DK" in November 1954 followed by the 5E6 Bassman Amp during early 1955. The 5E6-A Bassman model was introduced later that year and included some evolutionary improvements. Demand for the tweed Bassman amp grew, so Fender increased production. By the middle of 1957 more than 1,500 examples of

810-604: The tube Bassman 300 continued on until 2013. In 2009, Fender introduced the hybrid Fender Bassman TV series with a tube pre-amp and solid-state power amp. These were available as the Ten (150W 10" combo), Twelve (150W 12" combo), Fifteen (350W 15" combo), and the Duo Ten (350W 2 × 10" combo). Freddie Tavares Frederick Theodore Tavares (1913 – 1990) was an American designer, engineer, and musician who played with Bing Crosby , Dean Martin , Henry Mancini and many others, and

840-462: Was 50 watts at 8 ohms into a single 12 inch speaker, with a "Tone Ring" baffle in the speaker cabinet. In early 1961, model 6G6-A was introduced with a solid state rectifier replacing the GZ34, and two 12" speakers with a conventional baffle in a slightly larger cabinet (wired in parallel) with a 4-ohm output. In 1962, model 6G6-B was introduced, which incorporated circuit changes but used the same speaker configuration. In 1963 smooth Blonde Tolex covering

870-620: Was also a key figure at Fender Musical Instruments Corporation for many decades. Tavares is perhaps best known for his role in designing the Fender Stratocaster and other Fender instruments and amplifiers (including the classic Bassman amp). Frederick Theodore Tavares was born on 18 February 1913 in Maui, Hawaii . He was a virtuoso on the steel guitar , playing on many hundreds of recording sessions, radio broadcasts and movie soundtracks. The signature steel guitar swoop at

900-495: Was used instead of the early rough texture cover, and a light tan grill cloth. In late 1963, Fender changed the cosmetics to what is commonly known as the "blackface" scheme. This amp still had the presence knob and same circuit (designated 6G6-B) as the smooth Blonde Tolex Bassman, but the faceplace was now black, the Tolex was black, and the grillcloth had moved to a silver cloth with black thread. The logo had also transitioned from
