An icon, the Ampeg B15N Portoflex is the true genesis of the bass amp. Designed initially for double bass players by Jess Oliver and introduced in 1960, it would soon be found on stages and recording studios all over the world. Used by luminaries such as James Jameson, Rick Danko and John Paul Jones, one even made an appearance on the Dick Cavity show supporting Jimi Hendrix, this was the sound of the electric bass guitar as it became the backbone of popular music through the 60s and beyond.

This one is in really exceptional condition, the plexiglass Ampeg logo still lights up, and it's even equipped with some of its original Ampeg branded valves! It works perfectly and sounds killer!

The original Tolex and grille are in excellent condition with just a few marks here and there - please see the pics. The front panel is very clean and the original speaker provides lots of oomph as you would expect.

If you are looking for an original version of one of these iconic amps then we doubt if you will find a cleaner one that is in such good condition and works as well as this one does.

Perfect as a studio tool or a must for any amp collection...
