What is an IR and why should I care?
A speaker cabinet impulse response or “IR” is essentially a digital audio snapshot of a cabinet that captures the acoustic characteristics of that specific cab, along with the signal chain used to record it—microphone(s), preamp(s), cable, etc.—and the room in which it was recorded. IRs allow you to “virtually” switch between different cab sounds in the same way you would swap physical cabs.
SGT-DI is the first physical Ampeg product featuring IRs and IR loading.
SGT-DI comes with six preloaded Ampeg factory cab IRs, three of which may be replaced with your own:
Cab Mode includes Ampeg Heritage B-15, Heritage SVT-410HLF, and SVT-810 Squareback IRs.
User Mode includes overwritable Ampeg SVT-112AV, SVT-210AV, and SVT-212AV IRs
The Cab Level control enables you to adjust and save the amount of cab IR sound in your signal.
The IR Off Mode bypasses the IR circuitry altogether.

Haven’t had this pedal for long, so still figuring out all the options, but man, there is some BIG sound coming from this unit. Not just big, but an authentic Ampeg sound. Choices between different cabs, the ability to download your own favourites and choosing between the B15 or SVT sound with or without grit…so many options. Play grunge, blues, slap, classic rock, mellow, hard driving you name it, you should be able to dial it in. This also gives you the ability to bring it to a gig on its own or run it through your amp. Again, tons of options. No regrets picking this up. A headphone jack and input jack give you the ability to use it as a practice tool. Expert or novice, there’s something for everyone with the Ampeg SGT-DI Highly recommend.
