A Powerful, Tonally Rich Bass Preamp and DI

Power and tone. These attributes are what you’ll find in an Ampeg product, and the SGT-DI Bass Preamp Pedal/DI proves this masterfully. Built with time-tested Ampeg technology, the SGT-DI sculpts your bass tone with plenty of low-down bite. The Super Grit Technology overdrive circuit sits at the heart of this monster’s beastly capabilities, featuring the iconic voices of the Ampeg SVT and B15 just waiting for sonic liberation. This preamp-meets-DI stompbox offers up a 3-band EQ to fine-tune your bass sound, with the capability for sweepable mids. But the SGT-DI takes it further by adding Ultra-Hi and 3-way Ultra-Lo switches and a variable 10:1 compressor. Perhaps the most stunning feature of the SGT-DI stompbox is Ampeg’s first IR/cabinet simulation with three classic factory cabs loaded in. To sweeten the pot, you can load in three cabs of your own through the free Ampeg IR Loader app. Bassists around Sweetwater agree: this is one rad all-in-one bass box you’ll need for your rig.

  • Super Grit Technology overdrive circuit packs the roaring voices of the iconic Ampeg SVT and B15

Killer

All I've used since I picked it up

Forgot to add

I sold my Ampeg SCR-DI and regretted it
Its sound was awesome but limited.
What I really missed about it, it had the best headphone amp in it I have ever heard and miss it!
Well got this device and it must use the same circuitry cause the headphone amp is worth the price of this unit alone!
I use it with my Xvive IEM and sounds amazing!

Rarely write a review but

I was prepared to be disappointed and return it before I even took it out of the box.
I have to say a rarely write a review but this thing is love at first listen!
I bought it primarily to do a Pretenders tribute band. I plugged in an active fender PJ and was met with glory after a little fiddling!
I have tried to achieve good pretenders tone with a number of other units but love this one!
Total Ampeg goodness!
Thank you Sweetwater and Hoel Helton my rep!
Love you guys!

The Review I Couldn't Find

Years ago I lost control of my Ampeg B 25 after decades of use both as a bass amp and an unsurpassed rock guitar amp. Video demos of the SGT-DI accurately revealed its true ampeg sound and so even though I didn't find a review of it used with guitar, I felt I couldn't go wrong with it at least for bass and so gave it a try. Indeed the SGT-DI does largely restore those Ampeg voices to me as my primary sound for guitar as well as bass.

That said, It's a DI through my studio mixer and monitors at low volume, not a living, breathing, 1969 55 watt tube head with a two 15 cabinet and vital ideas of its own. And I'm also trying to recreate memories of 30yo experiences in a much older body. But after a few hours working with the SGT-DI I was sufficiently overwhelmed with its versatility to give it 5 stars. (Very interesting impact with the compressor on string-to-string balance and the midrange control is fantastic.)

First of all, I noticed it is built for Ampeg by Yamaha and, true to their form, it seems like a mighty hunk of quality technology. I give both the design and the manufacture an A+.

Second is it's versatility. While I wish it included a B 25 mode, the B 15 and SVT modes both sound great and are close enough. In trying to get my old guitar sound with the same Peavey T-60 (Gibson Dirty Fingers in the bridge.. a truly awesome ax!), I discovered tremendous sound sculpting possibilities with this DI. There are also many ways to expand this with its extensive IO.

I am getting my old sound again and also starting something new!

Versatile. Absolutely worth it!!

I love the SGT-DI! I use it for a metal band and a pop/dance cover band. It works well for both bands, I pretty much just switch from the SVT to the B15, grab the other bass and that's about it. The voice and cabinet models are awesome, they really do have that Ampeg sound!

It's built SOLID. Yeah the cabinet knob on the side is plastic, but it's not the kind of thing you'll find your self messing with everyday. Plus it can be hidden anyway.

The compressor is fine, ignore everyone knocking it. It doesn't sound very musical; sure, that's the point. If you want something with a little more character, use a different compressor. I use a little bit (set to about 9 o'clock or less) just to tame the active signal and it works just fine.

I did a lot of research before buying this thing and it's hands down one of the best values out there for a pre-amp/DI. I haven't messed with the IR's, mainly cause I'm completely happy with how this thing sounds. But props to them for making it a USB type-C!

This thing is very versatile. I love it. My bandmates love it. You'll love it.
