zZounds Gear Experts Say...

A tribute to Ampeg’s heritage, the SGT-DI blends a powerful preamp, Super Grit Technology overdrive, and EQ controls to shape legendary SVT and B15 tones.

Overview

The Ampeg SGT-DI Blue Line Anniversary Edition is an all-in-one Bass Box. This SGT-DI Blue Line Anniversary Edition preamp and DI is identical to the silver Ampeg SGT-DI -- but it's blue! The same blue as the original 1969 "Blue Line" SVT amplifier.

The SGT-DI preamp and DI gives modern bassists an entire rig in a single stompbox. It delivers an enhanced Super Grit Technology(TM) overdrive circuit featuring iconic Ampeg SVT and B15 voices, versatile 3-band EQ now with sweepable mids, Ultra-Hi and 3-way Ultra-Lo switches, a variable compressor, and an Aux /Headphone section. The SGT-DI also includes an IR Loader/Cab Simulator.

Get the 75th Anniversary Free IR Pack, which includes the SVT-610HLF, SVT-810AV, and SVT-15e cabs.
