- 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 first Princeton, the "Woody" (so called for its uncovered wooden cabinet), was the smallest of the original Fender line of three amplifiers, an incredibly basic 3-watt practice amp with no controls at all, not even a power switch. The first widely produced Princeton, the 1948 tweed-covered "TV front," used one or dual-triode tube to provide two stages of RC-coupled voltage amplification in the preamplifier section; the power amplifier section used a single cathode-biased 6V6 beam power tetrode necessarily in Class A operation. The amplifier had a single volume control and a simple low-pass tone control to control treble response. The Princeton circuits up through 5C2 differed from the Fender Champ in having two versus one preamp stage (6SC7 dual-triode vs 6SJ7 pentode) and added the tone control that was absent in the Champs; the 12AX7-based Princeton models 5D2 through 5F2-A were essentially the Champ circuits 5D1 through 5F1 with a tone control and a somewhat larger output transformer. In 1956 the Princeton received a new cabinet roughly half again as tall and wide as the previous Champ-sized "small box." In 1961, a new Princeton (6G2) of fundamentally different design was introduced, which instead of being essentially an upgraded Champ was more like a junior Deluxe. This "brownface" version used a single 7025 dual triode in the preamplifier; a 12AX7 dual triode, one half of which operated a tremolo oscillator and the other half of which served as a split-load phase inverter; and two 6V6GT tubes, which were fixed-biased in Class AB push-pull configuration in the power section. In 1964, the single tone control was replaced with individual bass and treble control knobs, and the base Princeton was joined by the Princeton Reverb. A pull-out "boost" switch was added to the volume pot in 1978. The Princeton is particularly famous as the basis for Mesa Boogie's Mark I, which is a heavily hotrodded Princeton equipped with modified preamp and a Bassman transformer, allowing it a higher gain output of 60 watts. Fender produced a solid state Princeton, the Princeton Chorus, from 1988-1991 ("red knob," made in USA) and 1991-1997 ("black knob," made in Mexico). This model was notable for its two independent 25.5-watt amplifiers running in stereo mode. Years of the Fender Princeton Chorus productions were produced from 1988 to 2001. In 2006, Fender revived the Princeton name, under "Princeton Recording-Amp" (Pro-tube series) and "Princeton 650" (under Dyna-touch III series). The Princeton recording amplifier is basically a blackface Princeton with built-in overdrive, compressor and power attenuator. Fender also reissued the Princeton Reverb in 2008.

- Le Fender Princeton était un amplificateur de guitare vendu par Fender. Il a été introduit en 1947 et abandonné en 1979. Lorsque Fender introduit le en 1948, le Princeton est mis plus en retrait par la marque. Les Fender Princetons (ainsi que leur sœur ampères Princeton Reverb), des premiers modèles jusqu'aux modèles des années 1970, sont très appréciés notamment en tant qu'amplificateurs d'enregistrement. L'original Princeton a utilisé un tube double-triode 6SL7 pour fournir deux étapes d'amplification de tension RC-coupled dans la section préamplifiée. En 1961 le nouveau Princeton est fondamentalement différent dans sa conception (simple 7025 triode doubles dans le préamplificateur, 12AX7 triode double, deux tubes 6V6GT dans la traction de poussée[Quoi ?]). Il est particulièrement célèbre comme base pour de Mesa Boogie Mark I, qui est un Princeton équipé d'Hotrodded avec un préampli modifié et un transformateur Bassman, permettant une sortie de gain plus élevé de 60 watts. En 2006, Fender a relancé le nom de Princeton, sous les versions « Princeton Recording-Amp » (série Pro-tube) et « Princeton 650 » (sous Dyna-touch série III). L'amplificateur d'enregistrement Princeton est essentiellement un Princeton blackface avec haut-overdrive, compresseur et atténuateur de puissance. Fender a également réédité le Princeton Reverb en 2008.
