Portaflex series
Our exclusive Portaflex design has been hailed
as an important contribution to musical instrument amplification. It is the
only amp to incorporate the enclosed reflex baffle in a single unit, thus combining
superior acoustic characteristics with the finest amplifier design. This becomes
especially evident in the low bass frequency range that demands the ultimate
in dynamics. Here again you will find that Ampeg Portaflex amplifiers "speak
out" with a rich resonant "voice" that makes it the mark of the
true artist.
Ask most people about the Ampeg Portaflex and they'll think B-15. There were many more Portaflex models than most people realize. Even though this is a rather lengthy list of Portaflex products, it is incomplete. Where a model is listed but there are no specifications, it's because I know it exists but I don't know the details.
