MARSHALL 30th Anniversary equivalent?

I owned a bunch of these before i sold all my amps and went all things Fractal.

Does anyone know what the equal is? Chat GPT says BRIT 6100 - but there's no such thing.
Ive read the Capt Hookis good too - but the clean 1A is the only one close.

Any suggestions would be greatly appreciated.

Try including "be accurate" in your prompt for chatgpt. I haven't tried it for this case, but in other contexts i've found that to decrease the amount of just making stuff up it does. Really stupid that that's needed, or that it helps, but there you have it.
 
Just skip chatgpt imo.

Thats 3ch with modes right? Try the modern marshall models. Brit pre might work. Dont overlook the jvm stuff.
 
I would say the JSM or Satriani
jVM sig , he used the 6100 for years and they modelled it off that
It a bit more of a vintage JVM less compressed more open and less gain until you reach the highest modes
 
Id go with Splawn models with a JTM45 for the clean channel. A buddy had one years ago and i compared it to my Quickrod. They were simliar. Splawn was a slight bit meaner.

I used to own one of the 6100LE Blue Tolex/Brass Chassis EL34 versions for a while. It was one of the 800 that they made.
It had a great clean ch. The ch2 mode B (if I remember right) was supposed to be like an 800. I had an 800 at the time but it was a dual ch version. The 6100 sounded much better. I didn't care for ch 3 on it. I ended up selling it for the $$$$.
So, the clean ch and ch 2 mode B is what I really liked. To get in that area of Marshall tone here is what I have found:
The JMP-1 preamp CL2 is very close for the 6100 clean tone. The JMP-1 preamp is also very close for the ch2 mode B tone. You could also get there with a JCM 800 but the 6100 had a less muddy bottom end. You could probably use an 800 with a little low cut to get there.
I should note that I owned a JMP-1 at the time of the 6100LE and shortly after selling the 6100 I also owned a JCM 2000 DSL. The DSL high gain ch was sort of close in tone to 6100 on the ch3.
So, to sum all that up: If you want the clean ch and ch2 mode B tone of the 6100 I think the closest on the Fractal is the JMP-1 preamp but you have to deep dive a bit to get there. Like, bias it hotter and tweak the input EQ some....like boost some bass and tweak the mids a little.

Years later after I sold the 6100LE a co-guitarist band member brought in a 6100 but it was a Black version. At the time I was using my JMP-1 and using my DSL as a power amp. We both thought that my JMP-1 rig sounded a little better.
 
Another thing to add.....I remember while owning the 6100LE, I had a Visual Sound Jekyl & Hyde pedal. I could nail the dirt tones of the 6100 with that pedal going into the clean ch of that amp. It was scary close in tone.
 
There are 2 versions, one with 5881 power tubes and one with El34. They are also slightly different, therefore sound different. By far the better sounding one is the blue tolex el34, that one sounds good clean and channel 2. Unfortunately, I don’t know if anything in Fractal land that nails it.
 
G'day Pete,

This is what I got from ChatGPT:

Here’s the most accurate Axe-Fx III guidance available right now for approximating the Marshall 30th Anniversary (6100 Series) tone using Fractal’s amp models (with verified sources where possible).

📌 What the Marshall 30th Anniversary (6100 LE / 6100) Actually Is​

  • The Marshall 30th Anniversary 6100 is a three-channel EL34 tube amp with Clean → Crunch → Lead channels, designed to cover classic Marshall tones across genres. reverb.com+1
  • It’s not a standard single-voiced amp like a JCM800 or Silver Jubilee — the channels have very different voicings. Wikipedia
  • Valve-powered EL34s and classic Marshall-style tone stack are key to its character, especially its crunchy midrange and punchy response. reverb.com

🎯 Closest Axe-Fx III Amp Models​

1) BRIT 800 / JCM800-Type Models​

These are often the closest starting point for Morgan-Marshall-style crunch tones.
✔ Model:
  • Brit 800 2204 or variants in the Axe-Fx III amp list to approximate Marshall-style crunch/lead.
    This model emulates a JCM800-era Marshall tone, which historically is close to the character heard in the 6100’s crunch and lead channels before effects. Fractal Audio Wiki
How to tweak it:
  • Gain/Drive: lower than modern high-gain amps — start ~10-30% before boosting with OD/Drive blocks if needed.
  • Presence: moderate to high for upper mids and presence cut-through.
  • Bass: moderate – avoid flabby low end that masks mids.
  • Cab block/IR: choose a 4×12 Marshall-style IR (V30 or G12M) for tighter low end and authoritative character.
This model represents the core Marshall tone family — not an exact 6100 digital clone, but very close in flavor.

2) Silver Jubilee-Type (Brit Vintage / Brit Silver)​

  • Axe-Fx models like Brit Silver (often interpreted from Silver Jubilee circuits) capture darker, thicker Marshall tones. medias.audiofanzine.com
Why it’s useful:
  • The 6100 crunch channel shares some tonal weight and thickness with Silver Jubilee-era voicings even though it’s not identical. Adjusting it can get you closer to the 6100’s crunch character than a standard Plexi or 50w model.
Tweaks:
  • Drive: lower → enough to avoid overly saturated lead.
  • Treble/Mid: emphasize midrange for that classic Marshall breakup.
  • Presence: moderate.

3) JVM-Type Models as an Alternative​

While not traditional, the Fractal JVM OD channels (e.g., JVM OD1/OD2) are very flexible and cover a big range of Marshall tones — including three gain stages that can pull anything from mild crunch to aggressive lead. Guitar.com
Suggested use:
  • Use OD1 (Green/Orange) for tight crunch → classic 6100 crunch voice.
  • Use OD2 (Orange/Red) for more gain / lead-like textures.

🔧 General Parameter Tweaks in Axe-Fx III for More “6100-Like” Tone​

EQ & Gain​

  • Bass: 40–50%
  • Middle: 55–70% (emphasize mids to replicate that classic punch)
  • Treble: 45–60% (controls clarity but not harshness)
  • Presence: 45–70% (for cut-through)
  • Gain/Input Drive: keep moderate – the 6100 isn’t ultra-high gain, it’s more dynamic.

🎚️ Cab Blocks / IR Suggestions​

A huge part of the realistic tone is cab & mic emulation:
✔ Use Marshall 4×12 IR (V30 or G12M)
✔ Mic choices like SM57 + MD421 blend emulate classic Marshall mic’ing
✔ Avoid scooped or overly bright IRs — you want punch and tight mids
Running Axe-Fx III through FRFR or power amp + cab will get best physical feel.

📌 Important Notes / Limitations​

  • Fractal does NOT have a dedicated “Marshall 6100-30th Anniversary” amp model. Users often ask for it, but the community notes that you must approximate using similar Marshall models. Fractal Audio Systems Forum
  • The 6100’s multi-channel design is not one single static circuit, so no exact one-to-one exists. The recommendation is to approximate — picking a base amp model that captures the character and using scenes or blocks for channel variation.

✅ Recommended Starting Preset Blueprint​

Amp Block:
→ Brit 800 2204 (or Brit Vintage / Brit Silver as an alternate)
Post-Amp Blocks (Optional):
→ Light OD/Boost in front for crunch shaping
→ Cab block with Marshall 4×12 IR
Global/Output:
→ Ensure FRFR or power amp modeling is optimized (no digital-only flat output unless using IRs)
Scene Setup Idea:
• Scene A (Clean/Crunch): lower Gain + moderate mids
• Scene B (Crunch/Lead): increase Drive + add slight drive block
