Fender Amplifiers - Blackendfaced

Blackendfaced

The Blackface Fender amplifiers were produced between 1964 and 1967. The first piggyback blackface amps (as well as the Princeton) had white knobs. After 1964 the amps had skirted black knobs. The blackface cosmetics were discontinued in late 1967; they returned for a brief period in 1981 before their discontinuation the following year.

Blackfaced cosmetics do not necessarily mean "pre-CBS" since the CBS company takeover took place in 1965 and amps with blackfaced cosmetics were produced up to 1967. After the buyout the front panels were changed from "Fender Electric Instrument Co." to "Fender Musical Instruments". No real changes were made to the amps until the silverfaced amps of 1968 where certain circuit changes made them less desirable than the blackfaced amps. This affected some models more than others. For example, the Twin Reverb and Super Reverb combos, along with the Dual Showman Reverb and Bandmaster Reverb "piggyback" heads were equipped with a master volume control while other models such as the Deluxe Reverb were not altered in any way except for the change in cosmetics.

Silverface cosmetics do not necessarily denote silverface circuitry, however. Leo Fender was notorious for tweaking his designs. During the transitional period from late 1967 to mid 1968, the circuit designs of the Twin Reverb and Super Reverb were altered to eliminate an uncommon but serious oscillation in the signal chain. These changes took some months to finalize, as Leo worked through some designs, and happened after the cosmetic changes. Furthermore, the schematic and tube charts that shipped with these models did not always reflect the actual circuitry. Fender had many leftover AB763 (blackface) tube charts left over well into 1969 and shipped these charts with silverface models.

Save for a few series (such as HotRod series), a majority of modern Fender amplifiers sports blackface cosmetics.
