Ampster or small tube amp or DSP or ……..

"Authentic" is entirely subjective. What you want is sound that works with the other instruments in the arrangement/mix.

I own a very nice Hughes & Kettner all valve amp which like most H&K gear features a built-in Red Box speaker emulator. last time I did any serious guitar recording we mic'd up the speaker and ran a line from the Red Box output and recorded both. IIRC the Red Box sound won out marginally when placed in the mix.

If you already have an amp and speaker that you like the sound of, I would record that, but also take a DI directly from the guitar. That way if your recorded amp sound doesn't work in the final mix you'll have lots of post processing options as well as the fact that the the guitar performance will have benefitted from the interaction between the guitar and the amplification.

I almost always record straight to the DAW with an amp sim and strive to get the best performance first. Then I’m in the cat-bird seat and can reamp the DI however I see fit. I personally don’t like playing guitarist and recording engineer at the same time, it’s much easier for me to sort out the playing first.

[Sam Spoons]

I'd record the amp/57 to one track and a clean DI to a second track.

So in a nutshell I’m playing lots more guitar and am ready to record some overdubs to my forthcoming EP.

For overdubs I'd be aiming for something that replicates the sound of the track(s) I'm overdubbing. Previous answers have covered the options of how to record sounds you might like, but overdubs are going to stand out if they're too different to the sound of the original guitar tracks. That might be what you're going for, in which case it's an artistic choice.

...to one track and a clean DI to a second track.

Always. It's not just about re-amping. It can be a huge help later down the line.

which could sound most “authentic”.

would read “authentic” as "unique" unless you're after a specific sound...

Hughes & Kettner all valve amp which like most H&K gear features a built-in Red Box speaker emulator

our initial foray into manageable project recording and has always managed to sound just that little bit different here. small, inexpensive and "real"

Scuffham S-Gear

has been and remains the goto here since it came out for anything not hi gain.
the most "playable" of any amp sim imho = the best performance

IK Tonex

just now exploring this ecosystem for the few things we can't easily get in S-Gear, might have some promise, despite a frustrating UX ( preset, tone model management, too many poorly (user) captured tone models (so far), ToneNET crashing, lack of responsive support, etc.)

If you don't like AmpliTube, I've had great results from all of the following for mid-gain tones. (I don't get too hung up on guitar sounds if the guitarist is happy when playing the tracks!)

Line 6 Helix.
Plugin Alliance software (eg Chandler/Orange/Friedman/Fuchs amps)
...with the right cabinet IRs.
Line 6 Catalyst.
Boss Katana (!)

Lots of choice for great tones these days.

If you're the really picky guitarist type you might be happiest finding a small tube amp you really get on with.

I don't think Tonex is enough of an improvement over AmpliTube really, to my ears, but I haven't had a lot of spare time to play with it.

Oh… it is. The captures change everything. That said, tonex will sound as good as the capture you’re using. I dont like most of the factory captures.

Hopefully this weekend I’m finishing a compilation track and need to redo a couple of guitar parts (well more than a couple if I’m honest ). So as you know, I’m going to mic my amp, but as you (the forum resident Jedi) also mentioned I’m going to capture a DI too. So, what’s the best audio splitter? I’ve looked at the Ekectro Harmonix switch blade plus https://www.gear4music.com/Guitar-and- ... iBHOfVTJAE

Would that suffice, and better options?

You need a DI box to record the DI. That will give you a 'normal', unbalanced 'thru' output to feed the guitar amp and a balanced mic level output to tap and record the DI.

Then if you do decide you want to re-amp the captured DI you also need a re-amp box. To this end I have a Little Labs Red Eye 3D, which handles both with simple switching between duties, but separate DI and re-amper boxes will also do the job. These days I'd likely opt for Orchid devices (DI and Amp Interface), which I have installed at one of the studios where I work regularly. Orchid's offerings are better value for money than the Red Eye.

Which model is the Blackstar amp Ian? Almost all of them have an effects loop and you can use the FX out to get a DI output, no need for more kit.

Some models also have an 'emulated' output (on XLR male on some models which I personally think is daft!)

In fact the only models I can think of that don't have at least FX out are the Artisan series but then these have 'high/low' jacks per input which is effectively a splitter.

Personally I always want to take my DI before it has entered the amp, but to each their own. If you can save the cost of a DI that's an option.
