Query: When did Fender produces their first guitar amp?
Leo Fender began building guitar amplifiers before he started manufacturing electric guitars. The first of these were the K&F models, produced between 1945 and 1946. The early K&F and Fender amplifiers relied upon vacuum tube circuitry, with the company adding solid-state models in the late 1960s.
The Fender Bronco was introduced to the market as a student guitar. It had been worked on since 1964 and then produced in mid-1967. It was originally supposed to replace the Musicmaster. It was initially sold as a "package" with the Fender Bronco Amp, a small amplifier also created for students.
The early, or first Tolex-made, 6G9 Tremolux Amps were the 6BQ5/EL84 amps starting at Serial Number 100. It is unknown how many EL84 style Tremolux amps were produced, but it is one of the rarest amps that Fender made and it is suspected that production totals were likely less than 300. The EL84 Tremolux did not have professionally printed tube charts, but instead they have a typewriter-written tube chart that was copied on a blue-ink mimeograph machine.
In addition to Fender amplifiers, Dale is associated with the Fender Stratocaster guitar. Fender makes a signature model, the Dick Dale Custom Shop Stratocaster, fitted with "Custom Shop '54" pickups and intended to recreate the sound of the first Stratocaster. Dale used a reverb unit with the signal split between two Fender Dual Showman amps. As of 2010, Dale continued to play with his original reverb unit and Showman amps from the early 1960s, continuing his practice of stringing his left-handed guitar upside down. The unique features of this guitar include a toggle switch that bypasses the three position blade switch to activate neck and middle pickups only.
When the Fender company invented the first widely produced electric bass guitar (the Fender Precision Bass) they also developed a bass amplifier, the Fender Bassman, first produced in 1952. This was a 26-watt tube amplifier with a single 15" speaker. In 1954, the Bassman was redesigned to use four 10" speakers. This speaker cabinet was an open-back design; as such, it had poor low-frequency efficiency and was prone to blowing speakers when used for bass because of the lack of damping. Somewhat ironically, it became very popular as an electric guitar amplifier. The circuit design also underwent repeated modifications. The "5F6A" circuit introduced in 1958 is regarded as a classic amplifier design and was copied by many other manufacturers, such as Marshall.
The Fender Musicmaster is a solid body electric guitar produced by Fender. It was the first 3/4 scale student-model guitar Fender produced.
A Musicmaster Bass model was also put on the market.
In 1933, Dobro released an electric guitar and amp package. The combo amp had "two 8″ Lansing speakers and a five-tube chassis. Dobro made a two speaker combo amp that was on the market over 12 years before Fender launched its two-speaker "Dual Professional/Super" combo amp. In 1933, Audio-Vox was founded by Paul Tutmarc, the inventor of the first electric bass (Tutmarc's instrument did not achieve market success until Leo Fender's launched the Precision Bass). In 1933, Vega sold a "pickup and amplifier set" which a musician could use with her/his existing guitar. In that same year, the Los Angeles-based Volu-Tone company also sold a pickup/amplifier set. Volu-Tone used "high voltage current" to sense the string vibration, a potentially dangerous approach that did not become popular. In 1934 Dobro released a guitar amp with a vacuum tube rectifier and two power tubes. By 1935, Dobro and National began selling combo amps for Hawaiian guitar. In 1934, Gibson developed prototype combo amps, but these never got produced and sold. By 1935, Electro/Rickenbacher sold "more amps and electric guitars than all the amps and electrified/electric guitars made from ’[19]28 through the end of ’[19]34, combined".
The Fender Deluxe guitar amplifier was produced by Fender from early 1948 to 1966. Its predecessor was the Fender Model 26 produced from 1946 to 1948.
In 1950, Fender introduced the first mass-produced solid-body Spanish-style electric guitar, the Telecaster (originally named the Broadcaster for two-pickup models and Esquire for single-pickup). Following its success, Fender created the first mass-produced electric bass, the Precision Bass (P-Bass). In 1954, Fender unveiled the Stratocaster ("Strat") guitar. With the Telecaster and Precision Bass having been on the market for some time, Leo Fender was able to incorporate input from working musicians into the Stratocaster's design.
The Fender Princeton was a guitar amplifier made by Fender. It was introduced in 1947 and discontinued in 1979. After Fender introduced the Champ Amp in 1948, the Princeton occupied the next to the bottom spot in the Fender line. Fender Princetons (as well as their sister amp the Princeton Reverb) from the early models into the 1970s models are highly valued particularly as recording amplifiers.
The guitars, bass guitars, and amplifiers he designed from the 1940s on are still widely used: the Fender Telecaster (1950) was the first mass-produced solid-body electric guitar; the Fender Stratocaster (1954) is among the world's most iconic electric guitars; the Fender Precision Bass (1951) set the standard for electric bass guitars, and the Fender Bassman amplifier, popular enough in its own right, became the basis for later amplifiers (notably by Marshall and Mesa Boogie) that dominated rock and roll music. Leo Fender was inducted into the Rock and Roll Hall of Fame in 1992—a unique achievement given that he never learned to play the instruments that he made a career of building.
Clarence Leonidas Fender ("Leo") was born on August 10, 1909, to Clarence Monte Fender and Harriet Elvira Wood, owners of a successful orange grove located between Anaheim and Fullerton, California.
Instruments used included his first guitar, a Guild M-65 Freshman and a Silvertone Twin Twelve amp. In 1964 he purchased a 1963 Gretsch Tennessean and a Fender Showman amp used in The Satellites. In Vietnam he used a Fender styled no-name guitar and a Fender styled no-name amp purchased in Vietnam and used with The Electrical Banana. In the Soft Light, 1968, he used a Fender Telecaster with a factory Bigsby and still using his 1964 Fender Showman. In late 1969 he purchased a Gibson Les Paul Custom Black Beauty used in Spectrum and Mad Wax. With Mad Wax in 1971 he ordered a Gibson Les Paul Custom with a sunburst finish built to his spec's from Gibson's custom shop, his main guitar until this day. Peavey amps were a new brand at that time and he purchase two British Stacks. He used the Peavey amps for only one gig and returned them to the music store the next day telling the store owner " You can keep this crap, order me a Marshall." He purchased two Marshall Super Lead 100 stacks. With Big Bubba & The Blockbusters he used one Marshall bottom and one Marshall Super Lead 100 for outdoor gigs, a 1964 Fender Bassman or a Marshall JCM 900 1-12 combo for in-door gigs. For the Satellites and Soft Light recording sessions he used the 1963 Gretsch Tennessean and the 1964 Fender Showman. For all other recordings he used the 1971 Les Paul Custom with the 1964 Fender Bassman. Other guitars purchased and used on gigs include a 1966 Rickenbacker 330 twelve-string, a 1971 Gibson Limited Edition Medallion Flying V #20, a 1983 Fender Stratocaster with EMG pickups, a 1992 Paul Reed Smith, a 1974 Les Paul Special/1955 Reissue.
The Fender Twin is a guitar amplifier made by Fender Musical Instruments Corporation. It was introduced in 1952, two years before Fender began selling Stratocaster electric guitars. The amps are known for their characteristically clean tone.
1999–Present: 1998 Rivera Fandango Amp(Late '60's Plexi and '59 Tweed Bassman / Twin Pre-amps), 2004 Acoustic Echo Amp, 2002 Fender BassBreaker Amp (Fender Custom Shop: based on 1959 "High-powered Tweed Twin Amp", 1967 Fender Custom Vibrolux amp, 2003 Soldano Avenger amp, 2004 Marshall 2000 DSL amp, 2006 Ibanez 427 Guitar for SLIDE, 2001 Guild DV52 acoustic guitar, and 1987 Warmoth Red Tint SuperStrat Guitar
Fender Contemporary Stratocaster electric guitars were produced by Fender Japan in the 1980s.
The Fender Contemporary models were the first Fender Japan models to be exported as Fender Stratocasters and Telecasters. The previous Fender Japan models exported from Japan were all Fender Squier models. The Fender Contemporary models were manufactured from 1984 to 1987 by FujiGen Gakki and these Stratocasters were designed to be Superstrats (Super Strat) with humbucking pickups and Floyd Rose like tremolos made by Schaller and Kahler. There was a lower priced Fender Contemporary Squier model produced as well.Many of Fender Contemporary Stratocaster and Telecaster models had Fender Japan E serial number prefix at the beginning of their serial numbers but in fact Fender never produced a line of guitars named the "E series". 
Compared to the major brands Fender and Marshall, the collectability and playability of the guitar amps is a mixed affair. While vintage Fender amps consistently command high prices, Ampeg guitar amps such as the Reverberocket can often be found for prices atypical of vintage amplifiers. In general, Ampeg guitar amps until 1964 are less desirable as they have a darker, cleaner sound even when pushed hard. With the introduction of the Galaxy line (Gemini, Mercury, Reverberocket) in 1964, treble boost circuits and spring reverbs were added, and higher wattage models (such as the 30 watt Gemini II) were made available. Original SVT bass amps are highly sought-after for their pleasing sound and were used by many professional bassists in the '70s. V series guitar amps (V2 and V4 heads along with the VT-40 and VT-22 combos) are sought after for the classic 70s crunchy but clean sound. The V4-B is another sought after bass amp head; it has the SVT pre-amp section mated to a 100 Watt power amp section.
The Fender '65 Twin Custom 15 is a guitar amplifier produced by Fender. It is a tube combo amp that pairs an 85-watt reissued Fender '65 Twin chassis with an enlarged cabinet and single 15 inch speaker. The Fender '65 Twin Custom 15 is comparable to the Peavey Delta Blues 115.
The Fender Pro Reverb is a high-end guitar amplifier made by Fender. It was in production from 1965 and was discontinued in 1982. The Pro Reverb is a 40-watt tube amplifier and has a pair of 12" speakers; however, models later than 1976 were increased to 70 watts. Teagle and Sprung, authors of the definitive book on Fender amplifiers ("Fender Amps: The First Fifty Years") described the Blackface Pro Reverb as "the" best amplifier ever produced likely due to its combination of the two twelve inch speakers, its high quality reverb and tremolo, and just the right amount of power to get either classic Blackface Fender cleans or natural tube breakup at reasonable volumes. They wrote, "the author recommends these amps as the best all-around amp ever made—by anyone".
The Fender Vibroverb was a 40-watt combo guitar amplifier originally manufactured in 1963 and 1964. It was the first Fender amplifier to incorporate on-board reverb which became a standard feature on many high-end Fender tube amps during the 1960s and 1970s.
Alec's collection of guitars includes, but is not limited to, two different Fender Telecaster guitars, a Fender Stratocaster, a Gibson Hummingbird, and a Gibson SG. He also has at least four acoustic guitars, two of which are made by Gibson. Alec employs the Vox AC30 amp to produce the sound he desires. On his recent tours with Clap Your Hands Say Yeah, he has been playing through a 4x10 Fender Hot Rod DeVille. On April 4, 2007, Alec sported a Gibson Flying V guitar on Clap Your Hands Say Yeah's appearance on "Late Night with Conan O'Brien".
His guitar style has changed somewhat over the years as well. In the 1960s he played Fender Jazzmaster, Gibson ES-335 and Rickenbacker thru Fender and Ampeg Amps. During the hard rock/metal craze of the 1980s Ron wielded Charvel's and Ibanez guitars with Peavey Amplification. From 2005-2010 Ron's main axe was a custom-wired Fender Stratocaster (designed by legendary Syracuse musician, the late Dave Pasternack). He uses a combination of Peavey and Fender amps. Ron is a fan of Digitech pedalboards, and has used them widely throughout the nineties and the 2000s. He currently favors Paul Reed Smith and the newly designed Charvel guitars for live performances. Ron uses a specially modified Fender CyberTwin 212 amplifier and a Morley Wah Pedal.

Dobro made a two speaker combo amp that was on the market over 12 years before Fender launched its two-speaker "Dual Professional/Super" combo amp. In 1933, Audio-Vox was founded by Paul Tutmarc, the inventor of the first electric bass (Tutmarc's instrument did not achieve market success until Leo Fender's launched the Precision Bass). In 1933, Vega sold a pickup and amplifier set for musicians to use with existing guitars. 
Standard amplifiers, such as the Fender "tweed"-style amps (e.g., the Fender Bassman) and Gibson amps, are often used by traditional rock, blues, and country musicians who wish to create a "vintage" 1950s-style sound. They are used by electric guitarists, pedal steel guitar players, and blues harmonica ("harp") players. Combo amplifiers such as the Fender Super Reverb have powerful, loud tube amplifiers, four 10" speakers, and they often have built-in reverb and "vibrato" effects units. Smaller guitar amps are also available, which have fewer speakers (some have only one speaker) and lighter, less powerful amplifier units. Smaller guitar amps are easier to transport to gigs and sound recording sessions. Smaller amps are widely used in small venue shows (nightclubs) and in recordings, because players can obtain the tone they want without having to have an excessively loud volume. One of the challenge with the large, powerful 4x10 Fender Bassman-type amps is that to get the tone a player wants, they have to turn up the amp to a loud volume.
After Ford's "Talk to Your Daughter" album was released in 1988, Robben used a Robben Ford Signature model guitar created in a collaboration with Dan Smith of Fender and produced in Japan between 1987 and 1993. That guitar was based on the Fender Master Series Esprit Ultra that was produced from 1983 to 1986 in Japan. In 1987, new management at Fender authorized the first production of the Robben Ford Signature guitar. In 1994, production of the guitar moved from Japan to the Fender Custom Shop. Three models were produced: Ultra FM (with a carved maple top), Ultra SP (with a carved spruce top), and the Elite FM (with a carved flame maple top). The guitar line continued to be produced until 2002 when it was discontinued by Fender.
Knowles uses a number of different guitars while on stage. His primary electric guitar until mid-2009 was the 1962 Fender Stratocaster Reissue, which he uses with Fender's SCN Samarium Cobalt Noiseless Stratocaster pickups. Knowles's other electric guitars are the Stevie Ray Vaughan Model Fender Stratocaster and Rio Grande brand pickups. Knowles uses the reissued Fender Mustang, which is only currently available in Japan. Knowles has one acoustic guitar that is used when he performs, a Gibson J-45 Acoustic. Along with these guitars, Knowles also uses Dean Markley guitar strings, ranging from 0.10 to 0.52 gauge. In mid-2009, Knowles began primarily using Paul Reed Smith guitars and Budda Amps while onstage. Knowles now uses PRS guitars, particularly the PRS 305.
