The Ampeg SGT-DI Blue Line Anniversary Edition is a versatile bass preamp and direct box that brings Ampeg’s iconic amplifier tones into a compact, pedalboard-friendly unit. Created to celebrate Ampeg’s 75th anniversary, this special edition features a distinctive blue finish inspired by the company’s legendary SVT bass amplifier.

Designed for both live performance and studio recording, the SGT-DI combines classic Ampeg tone shaping with modern signal processing, allowing bassists to achieve everything from warm, vintage sounds to powerful, aggressive rock tones.

At its core is Ampeg’s Super Grit Technology (SGT), which provides switchable overdrive to add grit, punch, and harmonic character to your bass sound. The selectable SVT and B15 voicings offer two distinct tonal personalities: the muscular, cutting presence of the SVT and the rounded, warm response associated with the B15.

The pedal also features a three-band EQ with adjustable midrange, onboard compression, and speaker cabinet simulation through impulse responses (IRs). These tools let you fine-tune your sound for different instruments, playing styles, and performance environments without requiring a traditional amplifier and cabinet.

For connectivity, the SGT-DI provides a balanced XLR direct output for sending your signal to a mixing console or recording interface, along with dedicated amplifier and instrument-routing options. Headphone and auxiliary inputs make it equally useful for quiet practice, rehearsals, and playing along with backing tracks.

Key benefits

It is particularly well suited to players who want a complete bass-rig sound without carrying a full amplifier and speaker cabinet.
