The Brownface series was introduced in 1959 and discontinued in 1963.
Fender amplifiers began making a name for themselves with the Tweed series, so called because of their cloth covering, which is actually varnished cotton twill (tweed is a coarse woollen fabric, commonly used for jackets, coats and caps; it is often woven in a twill pattern, which is likely the reason for the confusion over naming.) They were produced for more than a decade and are now eminently collectible and praised for their sound quality.
The twill was first used in 1946 on the Dual Professional a twin 10" 6L6 powered model of which only 400 were made before being renamed "the Super Amp" in 1948.
Even the most modern bands such as Bloc Party, No Age and Best Coast favour Fender’s timeless tone.
Leo Fender began building guitar amps before he started manufacturing guitars.
Fender guitar amps have been favourites of musicians across the musical spectrum from their invention in 1945.
The Blackface, Silverface, Brownface and Tweed Fender guitar amp ranges have come to help define the sound of many genres of music, from surf to shoegaze and country to electric blues.The construction of the amplifiers was changed as well: the chassis are mounted to the back with the tubes pointed down, as opposed to having the chassis mounted on the top of the cabinet.This has the benefit of providing ease of access to the inside while providing a strong top.At the beginning of the "tweed" era, Fender constructed many of its cabinets in "TV front" style, changing around 1950 predominantly to the"wide panel", where the top and bottom panel is wider than the side.Fender later on constructed them with "narrow panel", in which all the panels have more or less the same width.In the 60s, John Lennon favoured the Deluxe Reverb.
