I have tried Thomas Dill’s Fan Twin Surf, Fan S’champ Clean and Tone Junkie’s Purple plexi and they are all excellent, airy and very responsive, this is on a Mkll Stage. I have an Apollo Twin and a pair of Adam monitors. I’m intrigued by Null tests and comparison videos. Firstly, any valve amp recorded with the same settings and a minute gap between recording would fail a null test with itself and also because in many comparison videos I watch, the Kemper tone doesn’t match what I hear myself. One issue I had with the new OS is that my Stage didn’t shut down after it had been on for a while and I had to remove the cable.

The profiles you mention are heavily tweaked rigs (like amp compressor raised, clarity or tube bias adjusted, Bass middle and Treble adjusted, Bright Cab adjusted and so on). That's no problem and it's great that you like them. But this shows more the tweaking possibilities than superior profiling or how close they are to the real amp.

When ola’s video starts he presents the profile through the DAW, not through the cab. There it sounds identical. Even ola said that.

Tone wars is not THAT off man, it’s more woofy and compressed yes but I think you exaggerate a bit.

He starts comparing directly after profiling after 5 minutes in the video. If you think there it sounds identical, switching between profile and reference amp, I definitely can't help you. There is a massive difference! The real amp has way more high end and cut! The mids on the profile is shifted and it sounds very muddy and compressed. Honest question: What are you listening through?

And when Ola says: "That sounds... basically the same"; no guitar player says this in this way, when it really sounds the same They say spot on, identical, nails it, or indistinguishable, or can't tell which is which... Saying basically the same (with a pause between), says everything in this context

Quote from haruccigr

Ola’s video showed that the profile was identical. The diff came when he connected the Profiler to a real cabinet! Since the profile was merged he had to tweak slightly and then again became identical. He would have better luck if the profile was DI.

Tone wars showed that the QC was a bit closer to the real amp, true, however, the diff between kemper - QC was so minor that a small EQ can make these identical.

I can't remember any part in Ola's video where he was showing that the profile sounds identical?!

In the Tone Wars video the Kemper is WAY off. Like totally off. Something really must have been gone wrong in profiling process there. If you think this is minor, I can't understand and you should maybe listen with other monitors or headphones

I think this ties in very much with OS 14 Experiences.

I've heard how MK 2 2.0 sounds ... but I cant seem to find anyone - of any skill or reputations - who has done an A/B comparison of a MK2 2.0 Profile and A/B compared it to the real Amp it is capturing to demonstrate how accurate or not accurate it is MK2 2.0 is (?)

Anyone got any good links ?

Thanks

Alter amp works did a blind test and comparison video of real amp vs classic profiles vs 2.0 profiles. 99% of people thought the old profiling sounded closer, better, like the amp ...and thought it was the new 2.0 profile in blind test. But the true 2.0 was way off sounding from the real amp.

Tone Wars did a comparison between QC, real amp and Kemper 2.0. The Kemper sounded very muddy, compressed and WAY off from the real amp.

Same as in the video from Ola where the 2.0 profiling sounded weird, darker and congested.

Then there are some slightly better videos from Tone Junkie, bonedo and short clips from Dill were Kemper sounded clearer and bright, but noticeable different than real amp. And with the new dynamics there seems to be an overly clanky pick attack and harshness in this videos that aren't there in the real amp. Like missing some natural compression from the amp.

I haven't heard very convincing comparising videos yet. If there is a good clip out, where 2.0 sounds indistinguishable from the real amp, please post it here. The closest was maybe some clips from Dee Dammers.

Not yet. But in the German-speaking section of the forum, Kemper team said, that the development team have plans to also apply the PROFILING 2.0 process when importing impulse responses in the future. What exactly that means, we don’t know.

IRs sound best when used with direct amp profiles imo. Not the same quality as with external ir loader and longer IRs, but still very good (and a bit more focussed and direct sounding).

I did the same with ToneX and Kemper (even accepting higher overall latency). My goal was to get rid of some (known) Kemper v1 shortcomings.

After some weeks I realized I added compression to ToneX and had to later EQ more in DAW than before. Also the feel with ToneX wasn't as good. Kemper (mk1) feels more fluid, and has less clanky and more pleasant pick attack (with some of my favourite guitar picks).

I still use ToneX sometimes for reamping, but I am back to my Kemper Toaster and loving it.

When using with direct amp profiles and IR I get rid of most Kemper low mid congestion and some are spot on compared too real amp. Kemper sounds maybe a tiny bit more warm and polished - but I like it now! In the end it's all about personal preference.

The only thing I would like added is something like the Fractal Dynacab feature, that works so easy and sounds good.

That said, Sonulab seems to be a great tool too!

Quote from quemper

That's a small shame. I thought one of Kemper's features was that no firmware update would changed how existing sound (unless strictly necessary). This is a huge benefit relative to Fractal where every update means checking/updating all your presets. In keeping with that principle, I would have preferred to increase the loudness of the 2.0 Rigs rather than lower the loudness of the 1.0 Rigs.

It's good to know this and would be good to add to the release notes. FYI, I thought it was my speakers that were having a problem.

I think the more dynamic 2.0 profiles can produce higher peaks for example pick attack spikes, so they need lower volume to avoid clipping and headroom issues. And it's safer to reduce volume of classic profiles to get same perceived loudness.

But that should be mentioned in changelog or communicated when suddenly all the profiles are lower in volume. The important point is, where in the internal gain staging adjustments or improvements have been made. Like if there is some adjustments in pre amp gain staging or if there is only volume reduction right before output.

Quote from G String

The adjustment was made to ensure that the Classic and 2.0 profiles have the same perceived loudness. Just globally increase the output loudness accordingly and your Classic profiles will sound the same as before + your 2.0 Profiles will work fine as well.

As said, I already volume matched and it had a slightly different feel and pick attack. As if using a different pickup or changing string height.

Recorded sound sounds similar, but maybe little less density. It feels as if the volume drop is not only after the amp, but somehow affecting the signal hitting the amp.

Quote from huibuh

Hi. I'll do that digital comparison. (next week, when I am back home). I expect that there are less differences. But that must be excluded of course. I am using the released FW 14 on both. But I don't think that the FW made a difference..

I think OS version does make a difference. On the new OS14 classic profiles now have noticeable less output than on OS13. Maybe Kemper needed more internal headroom for the new 2.0 profiles and they had to adjust gain staging or something.

Before that, from OS12 to OS13, why is there less bass in the graph? Did they change low-frequency resonance while working on cab resonance or other cabinet refinement?

Why does Kemper not explain?

Questions to Kemper team: After updating my MK1 to OS 14 I noticed that classic profiles sound noticeable quieter (around 4 dB). Even when volume matched, the pick attack feels a bit different, as if very slightly less hot pickups were used.

Can you clarify where this volume change happens in the signal chain? And why? Giving more headroom? Is it because of some global internal scaling before the amp section or elsewhere? How does this affect feel, dynamics and sound?

Is the volume drop at the cost of a slightly lower signal-to-noise ratio?

After updating to OS 14 (release) today, I can confirm that the same happens on Mk1 unit: Output volume of my rigs has dropped noticeably. I made some test recordings and my DAW shows at least 4 dB less output volume!

Also noticed that all my classic rigs are now way lower in volume on OS14. All settings are the same. To confirm my impression I did make recordings and rolled back to OS 13. And yes in DAW it shows clearly that OS14 is around 4dB less volume!!

After updating to OS 14.0.3 Release and Rig Manager 4.0, Rig Manager has become very laggy when selecting or activating rigs. The Kemper unit responds immediately and plays back correctly, but switching rigs within Rig Manager is shown noticeably slow. I click or double click on a rig and it takes several seconds until it responds visible. I can’t work like this at all and will have to roll back to the previous version. I sincerely hope this isn’t related to having a large number of rigs, as I use Rig Manager as a large amp and cab library, which has worked perfectly well until now.

Quote from Kellerblues

Thar sounds like an improvement , not a bug

Kemper team clearly said that: "Profiler OS updates do not alter the sound of existing Profiles. It’s a core principle for us that this must never happen.

Over time, there have been a small number of rare cases, typically related to effects, where something changed unintentionally. These were not deliberate changes, and whenever we identify such an issue, we correct it promptly and release an update."

Quote from Hallan

I would suggest you to try Boutique Tones free pack!

! I bought Steve Lukater pack and I am very happy with it..

Boutique Tones are NOT offering 2.0 profiles.

Thank you for sharing your findings.

Please also report this direct to Kemper support so they can take a look at it. That would be very important and could help uncover potential bugs.

And please let us know what comes out of it.

Quote from G String

Yes, please use 14 beta. We made a few updates related to Profiling 2.0 playback on MK1 after the latest OS13 release.

This was asked explicitly multiple times across different threads… without any response until now. It's extremely important and needs to be clearly communicated if 2.0 profiles are NOT played back correctly (in lower resolution of course) on MK1 with OS 13.

Quote from RDM

Ibot39 you've been clear about your set up and I think it would help if everyone made it clear what the combination of the following three variables is to ensure everyone is comparing the same thing:

• MK1 or MK 2 Kemper
• 13 or 14 OS
• Classic (1.0) or 2.0 Profile

You are hearing a problem with 2.0 profiles on a MK1 using OS 13. What does the same 2.0 profile sound like on your MK1 Kemper using OS 14?

I think you are keen to stay on OS 13 as the two extra cabinet controls (albeit not functioning as per the same controls on a MK 2 using OS 14 based on the explanation provided by the Kemper team) will be gone if you update to 14.0; however, you can always go back to 13.0 after you've tested 14.0.

I am not a beta tester and I won't experiment with beta, reverting back and forth, like I did in the past. I need a perfect running Toaster.

I already posted a video from a Kemper private beta tester that stated and showed clearly that a 2.0 profile sounds thin and inferior on Mk1 compared to a classic profile of the same setup. Mr. Kemper himself responded: "He is a private beta tester as well and has made this video with an older internal beta version, unfortuately." But the beta tester told me that this is not true and he was using the latest OS for the video.

I think Kemper will figure it out by themselves or get in contact with their beta testers IF something is wrong in the conversion of 2.0 on Mk1. For me it sounds as if some frequencies are missing in the low end and that will also explain the perceived lower volume.

...

the high gain 2.0 sounds like asingle coil when you use humbuckers im using latest os

This analogy sums it up perfectly!

Quote from G String

Ibot39 Which Profiler OS are you using?

Latest Release OS 13.0.5.61298
