Ampeg SGT-DI

I’ll preface this by saying that I haven’t been all that impressed with Ampeg’s new products for a long time, and I’m a veteran doubter of using preamps vs. just getting the right amp in the first place. Last night I finally got to hear a friend's SGT-DI in action and was blown away.

The rest of the rig was a Tone Hammer 700 into a pair of Barefaced 1-15 cabs, the bass was a boutique built vintage-style P. I won't say that it nailed real SVT or B15 tones, because without A-Bing with the real deal, I could be lying ;) It definitely reminded me of my own encounters with SVTs as provided backline at festivals.

I thought it had a great sound, though, way better than any SansAmp based rigs I've heard. The notes were distorted in a pleasant way, I told my friend I thought it had “fur” around the notes, nice and thick but no buzz, fizz or farting. He wasn’t aiming for clean, that’s for sure :whistle: It fit really well in the small room trio setting, playing blues and some Dylan and Van Morrison covers.

Almost every time I see him play he has a different amp, last time was a vintage Bassman 100 into a vintage Fender Showman 1-15 cab, he used a Walter Woods into Flite 1-15 cabs for a long time and he uses a real SVT when playing big stage rock band gigs. While auditory memory can be faulty, this might have been the best tone I've heard him get out of a P. I was the band’s original bassist some 30 years ago, and still sub once in a while when he’s unavailable, so I’ve sat in playing both his upright (his is sweeeet...way above my pay grade!) and actual vintage Fender Ps through his amp du jour. None of those rigs came close to delivering what I heard last night.

I doubt I’ll ever be in the market for an SGT-DI but anyone looking for an “SVT in a box” definitely needs to try one out. Home run from Ampeg this time.

The SGT-DI doesn’t like hot basses. I’ve mentioned this before. However I found a solution with a single dial. (And the solution can do other interesting and useful things as well).

My experience is it’s best with my passive Fenders. It’s a preamp after all. My Sadowsky and Spector already have onboard ones.
My active basses are no problem. I’m referring to passive basses with humbuckers. The SGT has no input pad available. You would think the gain knob would work and it does, but when you pull it back to “1” you pretty much lose the magic of the grit circuit.

Has anyone come across a video comparing the
SGT-DI to the SCR-DI?
I have the latter and I'm wondering if I should upgrade. I like the SCR-DI preamp but totally avoid the scrambler circuit and it's an invaluable practice tool for me.
I have, enjoy & use both. The SCR-DI for home practice and the SGT-DI for studio and ampless gigs. The SCR-DI has great tone but not many tonal options. The SGT-DI has multiple useful tone options w/ the sweepable mids, cab sims, and SGT circuit. Currently using the SGT-DI in the studio and I'm able to dial in what works perfectly w/ any style song.

Yes, the Scrambler section is useless, but a separate Scrambler pedal works great w/ the SCR-DI. I feel the same about the compressor on the SGT-DI, I prefer the Ampeg OptoComp.

To everyone who's putting this pedal to use, do you use the Cab Sim?

I really like the way the 4x10 sounds, but the cab sim injects some white noise into the signal that I don't like. If I just turn the cab sim off, all the white noise goes away. It's not terrible but the sound guy notices it.

Is it just my pedal? the nature of the cab sim on these pedals, that it's noisy? Just wondering what others have experienced.

I get some white noise when Cab sim is ON.
Its minimal but like you the soundguy at the church gig That I play notices it...

Yesterday I got mine and played with it for some hours. I quite like it, there's a lot of tones in a relatively simple pedal to understand for people like me who never used a pedal before and don't want to be tweaking a hundred knobs.

The only thing that I didn't get very clear is how the volume of the preamp and the level of the SGT interact when the grit is at 0. Is the level knob of the SGT supposed to blend the voicings of the SVT and the B15, or is it just to boost/cut the volume when kicking the SGT?

The SGT circuit is ahead of everything else. Think of the grit as input gain/character and the level as a master volume. You want to not crank both though because that will clip either the preamp circuit or cabsim downstream. Think of three stages as seperate pedals and it will make more sense. There’s a diagram earlier in this thread if that helps.

I do have two passive basses that have hot enough output that the sgt grit set to zero is not clean enough. I can bypass SGT but what’s the fun in that? I with they would have added a push button input pad. As it stands I’m using a unit67 pedal in front to adjust the input level, which I wish I didn’t need.

Bought one of these over the holidays to compare with my SCR-DI. Definitely is a warmer rounder sounding preamp. Still assessing the rest to determine if it’s worth the upgrade for home practice.

One question for the group… I’ve noticed my unit runs warm when left plugged in. Anyone else notice this? It’s noticeably warm not hot. My SCR never heats up so I want to make sure this isn’t a defective unit.

I've never noticed any heat [or even warmth, other than the tone:D] on my SGT-DI.

Picked one of these up as a Christmas gift to myself and it’s exactly what I’ve wanted this entire time. The tones this thing gets was the missing piece. My wife also paid for half of a Focusrite Scarlett 2i2 so I can start recording. So if I want to play the Ampeg through that so sound comes out of my MacBook should I connect XLR SGT>Scarlett but then where do I connect my headphones and bass? I just want to run the pedal direct so trying to ignore my amp for now. This is my first foray into recording and DI stuff so sorry for the questions but thank you for any pointers!

I like this description. I've heard this tone before and I'm really drawn to it.

I could be wrong but wouldn’t the headphone jack on the pedal override the output? If so, you’d need to plug into the Scarlet.
