Tubes, tubes, and more tubes! The new Ampeg SVT-VR is a vintage reissue of an early 1970s “Blue-Line” SVT head. The preamp stage, power section, and even rocker switches emulate the exact signal path, tone, and vibe of the original rock ’n’ roll workhorse. Authentic from its input jack all the way to its six 6550 output tubes, the SVT-VR is a must-have for rockers seeking that in-your-face Ampeg bass tone.

The harmonically rich sound and legendary performance of the Ampeg SVT are redefined in the SVT Classic. This dynamically powerful all-tube bass amp delivers a thunderous 300-Watts of unsurpassed quality, reliability and tonal flexibility. Although other companies have tried to capture the classic all-tube sound of ’60s and ’70s Ampeg bass heads, no one can touch the SVT.

Classic Series Heads are designed for players who are looking for the authentic, vintage Ampeg tube sound that has earned the respect of the industry. With a huge and diverse group of artists endorsements, including George Clinton (P-Funk), Gene Simmons (KISS), Dave "Phoenix" Farrell (Linkin Park), and far too many others to list here, the SVT-CL is a clear favorite. In the world of high performance bass amps it stands head and shoulders above the rest.

When only high-powered performance will do, turn to the SVT-1000 to get the job done. With up to 1350-Watts RMS output and state-of-the-art Optocoupler Limiters to prevent unwanted power amp distortion, the Ampeg SVT-1000 is a veritable workhorse. The Texture Control (“tube-emulation” circuit) can be used to overdrive the amplifier, creating a more aggressive sound—without any of the typical (and harsh-sounding) clipping often associated with solid-state electronics. The onboard 9-Band Graphic EQ can be used to fine-tune your sound, or you might want to use it to set up a “second channel” for bass solos, complete with its own independent volume control. When you think power—and useful features—think Ampeg SVT-1000!
