Champ II
Introduced along with the Super Champ described above, the Champ II was the most basic of the tube amps in the "Rivera-era" range of Fenders, having no reverb or extra gain switching. It was discontinued in 1983, along with the Bassman 20 (with which it shared the same metal chassis design), three years before the rest of the range, perhaps because its dearth of features was unfashionable at the time. It had the same colour scheme, power supply, output stage and stock speaker as the Super Champ but the preamp and phase inverter consisted of two 12AX7 tubes.
