Vintage 70's Sam Ash Oliver Sound Company B150 Model SA-156 Head

Designed by Jesse Oliver (The mastermind behind Ampeg's PortaFlex).
He left Ampeg and started Oliver Sound Co.
Effect-less 60W piggyback bass head. Equalization on these heads included Bass, Midrange and Treble, plus Ultra-High on Channel 1 and Ultra-Low on Channel 2. The new bass amps became the mainstays of the company and were also sold with the Sam Ash brandname. The Sam Ash logo has been removed from the front of the head, and please see all pics for condition.

Solidstate rectifiers, 6L6 power tubes, 6EU7 phase inverters

Amazing guitar head. Sounds way louder than a 60watt.

If you Google Oliver Sound you can find a great article from Vintage Guitar on these Oliver beauties.

VERY rare and hard to come by old school head at an excellent price!
