This 1970's Ampeg B15N Portaflex was the main bass amplifier at MSR studios (Formerly known as Right Track Recording) The amp has been well played by some of the best bass players in NYC and is responsible for holding down the bottom on dozens of hit records.
The current speaker is an Eminence 15" and as you can see by the photos the tolex is a little roughed up. We will do a run through in the tech shop prior to delivery. Great player amp for your studio with tons of cool history.
