In the world of high-performance bass amps, Ampeg's SVT amplifiers are in a class by themselves. In true Ampeg tradition, the SVT-4 PRO offers you more power, performance and flexibility than any other bass amplifier in its class.

SVT-4PRO offers an expansive palette of tonal options. The Frequency control allows you to select the center frequency for the Midrange control, giving you five distinct voicing options for the Midrange. And if that's not enough, you can use the 9-Band Graphic EQ to fine-tune your sound - or use it to set up a footswitchable "second channel" with a volume boost for your bass solo.

SVT-4PRO is designed for the player who wants SVT tone and performance (with a few modern enhancements) in a convenient, high-powered, rackmount design. With a huge and diverse group of artist endorsements, including Michael Anthony (Van Halen), Tony Levin (Peter Gabriel/King Crimson), Steve Bailey (Bass Extremes), and far too many others to list here, the SVT-4PRO is a clear favorite among professionals. In the world of high performance bass amps, the Ampeg SVT-4PRO has what it takes to really define your sound.
