When I use my real amps, I can switch back and forth with zero EQ or pedal changes.

I don't think that's a normal experience...

Real amps should also respond differently to different guitars and pickups.

Earlier modelers were often slagged for the exact reason that they "homogenized" all guitars... It really didn't matter because they all sounded very similar coming out.

Interesting, I’m not saying that every guitar sounds the same in my real amp rig. Each guitar’s voice comes though, I’m just saying I don’t make any gain or EQ adjustments to the amp when changing guitars, and they all sound great.

With all of the modeling solutions I have tried, two similar guitars (an SSS Strat and an HSS Strat) one sounds great but the other is almost unusable on the same presser.

Now, I do set all of my guitars up to have similar output, even with a mix of humbuckers, P90’s, JM style, Strat single coils, Tele single coils, TV Jones Filtertrons, etc… and have never needed to change amp or pedal settings.

I’m just trying to close that gap with the Axe III. I noticed some IR’s I got recently (that I really like) have a sizable dip in frequency response around 2khz - 4khz. I set up a PEQ after the amp to boost that range about 1.5 dB and it helped a bunch. That’s where all the ear fatiguing, nasty sizzle lives in a DC30, and I believe it’s a big reason I’ve had success changing guitars without changing anything else in my signal chain.

Thank you for the explanation! I have a question.

One of the areas modelers haven't been as accurate as amps for me is when switching between guitars, like from single coil pickups to a guitar with humbuckers. You see it all the time from content providers with presets for single coils and presets for humbuckers. When I use my real amps, I can switch back and forth with zero EQ or pedal changes. I feel like the answer to this is in the upper mids/presence range (2khz - 4khz) and maybe in the low treble range. Does the output transformer improvement help with that?

That’s because guitar speakers shave off upper and lower frequencies, where (close-mic’d and full-range) IRs do less so, unless EQ is used.

That's been my experience as well. I've never felt the need to create different presets for different guitars/pickups using the same amp model. Each preset is created with the guitar that will typically be used for the song, but I've used different guitars with the same settings and they sound just as good without making any EQ or gain adjustments.

I use Global Amp blocks and most of them configured as a 4-channel amps with different gain levels and it's rare to need to make Level adjustments when going from humbuckers to single coils or vice-versa.

I think this explains it. You will not really need to adjust gain if you have relatively same amounts of input hitting the front end of an amp.

EDIT: EQ can be a different story, but in my experience, the closer a single coil is to the strings, the less shrill it tends to get (especially in the bridge position) and therefore you don't need to roll back the treble or presence on the amp. This isn't the case with all single coils, but yes, I have been surprised when I raised the bridge pickup on my Tele and it sounded very good through my usual high gain patch.

That's true!

I compared my presets on both my units running on 28.04 and 28.05b using a switch to change between both units.
Some of my presets went less bright, some went more bright.

But it's not that much that it could harm my presets.
I will not retweak any preset for the next gig on saturday.

If an IR is a capture of a speaker, how does the IR capture frequencies the speaker doesn’t produce?

Because close-mic and on-axis is not the same as far-field and off-axis... And also add to that the proximity effect of the mic

PS: it's not right to say the speaker doesn't produce those frequencies, they're just more or less attenuated/boosted by those variables

I don't agree with any of that. Whatever you're hearing is not an inadequacy in amp modeling. More likely it's "amp in the room" vs. close-mic'd IR.

If I’m not mistaken, “high” and “low” inputs and “bright caps” on vintage amps were an attempt to solve the problem of too much difference between guitars.
 
Might be placebo, but I want to share an experience with 28.05.

Assume a preset with two mid gain and high gain tones. Assume that you do the volume equilization while power chording on low strings. Before 28.05, I sometimes noticed that the high gain channel was weaker while playing the 3rd or 4th string solo. Now the high gain sings more uniform across the spectrum.

Could be a compression thing?

The output transformer improvement has eliminated something that has baffled me for years. Previously I would always measure a slight dip in the midrange response relative to the real amp. Not a lot, around 0.5 dB but still not perfect. I finally figured out what was causing this.

I think the removal of that “dip in the midrange” could account for what @ertan is hearing on the 3rd and 4th string.
