When only the best will do, turn to the SVT-8PRO for ultimate power and massive Ampeg tone. The SVT-8PRO combines our vintage SVP-CL preamp with a 2500-Watt Solid-State power amp for Earth-shaking bass that just won’t quit. Loaded with professional features throughout, the SVT-8PRO was designed for the most demanding player and the most demanding of gigs.

An outstanding feature, unique to the SVT-8PRO, is its speaker emulation circuitry, which allows players to dial in classic SVT overdriven tones at any volume level. This means you can get all the crunch and grind of an SVT pushed to the limit, but at a volume level that won’t set off local seismic detectors.

Our 5-position Ultra Low selector gives you low frequency tone-sculpting capability like never before. From the fattest low-end to tight, highly articulated punch, the choice is yours. And the built-in DI can patch you right into the front of house, although you probably won’t need it! Bottom line: SVT tone at concert volume levels, in a lightweight 23-pound package.

The harmonically rich sound and legendary performance of the Ampeg SVT are redefined in the SVT-2PRO. This powerful all-tube bass amplifier delivers 300 watts RMS of unsurpassed quality, reliability and tonal flexibility, and features a vast array of contemporary enhancements. 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.

The SVT-2PRO is all about tone. Sure, you’ve got control over the bottom and top end of your sound, but the SVT-2PRO takes it a step further. The Frequency control allows you to select the center frequency for the Midrange control, giving you a choice of five distinct “voices” for the midrange. The center frequencies are 220Hz, 450Hz, 800Hz, 1.6kHz and 3kHz. And if that’s not enough, you can use the 9-Band Graphic EQ to custom tailor your sound even more. Or use the EQ to set up a footswitchable “second channel” for your show-stopping bass solo. The SVT-2PRO—unlimited tone, right there at your fingertips.

Designed for the player who wants SVT tone and performance (with a few modern enhancements) in a convenient rackmount design, the SVT-2PRO has a huge and diverse group of artist endorsements.
