Features
In the world of high performance bass amps, Ampeg’s SVT amplifiers stand alone. Keeping with true Ampeg tra-
dition, the SVT-2 PRO Bass Amplifier offers you more performance and flexibility than any other amplifier in its
class. Listed below are some of the outstanding features of your new preamp - features which set it apart from the
competition! Additional information on these features can be found on the pages indicated.
• ATTENUATOR: A switchable input pad, this feature is perfect for basses with active electronics or
very “hot” pickups (page 4).
• MUTE SWITCH: Lets you cut the sound from the amp, letting you tune your bass in private (page 4).
• ULTRA LOW, ULTRA HIGH AND BRIGHT SWITCHES: Lets you tailor your sound in many different
ways “with the touch of a button” (page 4).
• 5-POSITION MIDRANGE SELECTOR: Take your pick from the five center frequency points available
to get just the right midrange voice (page 4).
• 9-BAND GRAPHIC EQ: Use as a “second channel” for bass solos, or to shape your sound to your own
exacting standards. An independent level control lets you adjust the Graphic EQ volume. Switchable at
front panel or with a footswitch (page 4).
