Fender 1970 guitar and bass catalog. Page 54. Details of the Fender Bronco Amplifier.
The Fender Bronco was basically the same as the Vibro Champ on page 52 - both were 6w, three-tube amps, with the same controls, and the same 8" speaker cone. Naturally these were listed at the same price, $99.50 in April 1970.
