Fender went ten years without a solid-state amp, after they discontinued the First-Series and Zodiac lines in 1971. In 1981, Fender produced some small solid-state amps and snuck them in with the tube amps. These first two amps were the Harvard and the Harvard Reverb. The Harvard sold for $189 and the Harvard Reverb went for $239. These amps were marketed for the student player and offered the amp with the new Fender Bullet guitar. The tube Champ amp and Harvard were available at the same time. You could get a fully-loaded solid-state Harvard for the same price of a wimpy, basic Champ. After this, the Champ was switched to the Super Champ, and the bottom line of Fender amplifiers have been solid-states from here on. At the same time a Bassman Compact amp was released and lasted until 1983. In 1982, Fender released a whole new line of solid-state amplifiers. These amplifiers were mixed right in with the tube amps for the 1983 catalog. These models included the Harvard Reverb II, Yale Reverb, Studio Lead, Stage Lead, the Montreux, London Reverb, Showman, and the Sidekick 10, 20, and 30. All of these amps lasted various lifespans, and had many different styles. Most of these amps were made and sold new between 1981 and 1987. CBS Fender was sold in 1985 and leftover stock of these models were sold into 1987. Remember Fender stopped making these amps in 1985, but they still sold them through 1987.
