Ampeg HERITAGE B-15 - Manual (Page 4)

Heritage B-15 Bass Amplifier
4
Introduction
Hand-wired and assembled in the U.S.A.,
the Ampeg Heritage B-15 delivers legendary
tone in a design that truly lives up to the
iconic standard set by inventor Jess Oliver
over 50 years ago. The Heritage B-15
features the circuit paths of both a 1964 and
1966 B-15, including classic Baxandall EQ
controls and premium 6SL7 octal preamp
tubes along with a bias switch, recreating
each years’ distinctive bias methodology.
The extremely high-quality flip-top
cabinet features the legendary double-baffle
design and houses a highly-researched,
custom-designed 15" Eminence driver. The
Heritage B-15 is no mere tribute; it meets
and exceeds the performance, look and tone
of the legendary original, down to each and
every component.
In order to get the most out of the
Heritage B-15, please read this manual
before you begin playing.
Best of luck in all of your musical
endeavors!
Sincerely,
The dedicated team at Ampeg
