Ampeg Portaflex

From Wikipedia, the free encyclopedia

The Portaflex is a line of amplifiers created by Ampeg. Originally designed by Jess Oliver, the main characteristic of the Portaflex is that the head of the amplifier is stored inside the cabinet and flips over when being used. The Portaflex line has many different configurations.

[edit] SB-12

Ampeg manufactured the Portaflex SB-12 model amplifier in the mid 1960's. It incorporated the flip-top design of other Portaflex amplifiers of the time. Although the SB-12 isn't as well known as the B-15 of the time, it is still highly sought after by musicians who use it mainly for studio recording.

The 'SB' in SB-12 stood for string bass. However, the amplifier was designed to be used by both guitars and basses. The SB-12 also incorporated two separate inputs, one labeled "Bass" and the other "Instruments." The '12' indicates the size of the speaker, in this case a 12-inch speaker. The SB-12 was a 25-watt amplifier.
