The Ampeg SVT-4 PRO 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-4 PRO 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-4 PRO has what it takes to really define your sound.

I matched this Ampeg SVT-4 Pro up with the SVT 6x10HLF cabinet and I couldn't believe what I had heard. From crisp clean highs, to driving mids, and thunderous lows it truely has it all. More tone options than you can possibly imagine for any kind of music. After 15 years of playing bass (5 of those professional)I have never played through a more versitle amp head. Also the 1200 watts gives you clatity and power to cut through multiple guitar players with a hard hitting drummer, and it does it with ease..........trust me!! Anyway, you don't have to take my word for it, just walk into any Sam Ash and test drive one!!!!
