try the Green Scream - (very) low Gain, Volume boost as needed (-> results in more amp gain) and Tone set to your taste (usually around noon)

add bass with the Tonestack

This has always been my go to method with tube amps but since I’ve used digital amps it never seems to react the same way. I used fractal for 10 years and now the Kemper for 2 and the pedal models or even analog pedals in front just seem very different from a real setup. The amp will overload much easier. Even with the TS with gain at zero. With real amps I would run gain zero and volume high as a front end push.

A high gain amp works by reducing the lows, drastically raising the gain(amplify), then apply some post EQ to bring it back to what it should sound like. If you dont remove the LOWs, the bass will dominate the distortion and go from flubby to a fuzz pedal.

Flub comes from too much bass entering the gain circuit. Meaning the bass is too high BEFORE the amp section.

The Kemper has a DEFINITION control in the Amp section that reduces the lows coming in from your guitar (before the amp). Most Marshall profiles will want the DEF around 6-7. Higher gain profiles may need to go all the way to 10. This also depends on how the profile was made. Sometimes the profile is a mess and has too much bass when it was made so Def needs to be at 10.

If that does not help enough, you can use a Graphic EQ in slot #1 and reduce the bass values. The GEQ will also let you boost mids a little or do some high freq cutting to tame the highs.

I would suggest starting with the DEF at 5 and going up slowly. At some point the guitar may start to sound clearer (it may still be too bassy). Then adjust the GEQ to remove the incoming bass.

A high gain amp may setup the incoming guitar signal to have a freq response similar to this. As you can see the LOWS are all being turned down to reduce flub/mud/bass/rumble. So using the GEQ to lower 64 Hz(-3dB),125Hz (-1.5dB),and 250 is where you want to adjust.

NOTE: I also like to put the noise gate AFTER the GEQ since lowering EQ values reduces some noise itself and makes the gates job easier. YMMV.

Do you place the geq before or after the amp/cab?

When you said add some post Eq, are you referring to the geq block or the Eq in the amp block?

I’m trying to dial in a 5150 liquid profile I found from the new stock profiles. I can’t remember which one I’ve used. I tried two different ones.

I can’t seem to get the tone to be be higher gain without the low end being flubby. If I dial back the bass and put a low cut on the cab it then sounds too thin and tinny. I can’t seem to find an in between.

Also, I can’t smooth out the high end without making it too dark and muffled. I’m trying to get a smoother higher gain like a brown sound. But it’s always either gritty and fizzy or dull and lifeless. Again can’t seem to dial in an in between

Anyone have any suggestions?

I’m using a humbucker bridge guitar into a Laney 212 FR.

When making a liquid profile set everything to noon (halfway).

I’ve been putting the tone knobs to noon and the gain to 10 per the manual. Maybe this isn’t possible with such a high gain amp

I’m attempting to run a liquid direct profile of my 5150 iii 50 W head on the red channel. I put gain all the way way up tone stack at noon, volume at about 11 o’clock. The profile process will not complete. I keep getting an error saying too much noise. Anyone have any ideas what the problem is? Does this amp just have too much gain to be able to profile properly?

When you're using a DI you can as well put the cab face down on a thick carpet so that the speaker faces the carpet. Additional blanket as BayouTexan said can take away a bit more then.

I do this with my trusty old Rocktron S112 which has a DI included and my fine Celestion CL80 in it. You still get some rumble and pictures off the wall but at least much less of the sharp highs that kill your ears when you're in the same room...

This isn’t bad for the speakers? No room for the air flow. It won’t blow the speakers ?

Quote from BayouTexan

Cover the cab with heavy blankets while ensuring the mic has room to capture the tone properly. This technique is called the "poor man's isolation cab booth".

I’m Not using a mic but I will try the blankets.

So recently i was making some profiles with my amps and suhr reactive load. I was told that the profile should be done with a cab load so i picked up the Kemper DI. It did make a small difference on the latest profile. However, the amount of volume im getting from the cabinet is insane. Its literally knocking pictures off the wall upstairs. Is there any good techniques for muffling the noise a bit so my house doesn't shake apart?

Hit me up if you’re selling one used. Thanks

you can find pretty much any statement about literally anything on the web these days, that doesn't surprise me at all.

I did however wonder about the point of bringing this up in this discussion.

anyway, back to topic please

In your opinion, is there a less expensive DI box that yields the same results as the Kemper box? I’d rather not spend $130 if I don’t have too. But if that’s what I have to do I will.

I read through all 12 pages of that old thread and there are so many random opinions that it’s making me just lean towards the Kemper box

Are one of the DI boxes better than the other? Is it worth the extra money to get the Kemper version vs for example the Behringer g100 or the Art Xdirect?

I have a radial Pro D2. Would that work as a direct box along with the cabinet as the load? Or will one of the direct boxes in the other thread yield better results?

Quote from DonPetersen

the point is, that the DI box has to be able to withstand speaker(!) level signals.

DI-boxes suitable to create Direct Amplifier Profiles

In order to create Direct Amp Profiles a DI box is required, but not every DI box is suitable for this job.

As the DI-box has to be placed between power amplifier and speaker cabinet it needs to be capable to handle such signal levels. Some DI boxes are only suitable for line level signals. Those cannot be used.

If the DI box should offer speaker simulation or attenuation, these features need to be inactive. Some DI boxes don't allow complete deactivation. Here is a list of a few DI boxes, which…

Is there any DI box that will allow me to either not use the cabinet or bypass the cabinet so I can profile without the cabinet being cranked at full volume? I like the quiet process with the reactive load but I want to get the best profile possible ?

I saw this. But im still confused on whether the DI box is simply in addition to the cabinet or are we using a DI that can withstand the load and that will protect the amp. Or do we still need to use a cabinet in this case. If were using a DI with no cabinet then isnt that essentially a load box? Like the suhr RL

So am i running the speaker out of the amp to the passive DI with a speaker cable, then the THRU to the cabinet with speaker cable and the DI out to the kemper with a regular cable?

Will this effectively take the load of the amp so i dont blow the amp?

Or i have a radial Reamp Box, wonder if that would work

Quote from DonPetersen

using a load box is not recommended for PROFILING

Im getting pretty damn good results this way. is it possible to make a direct profile using a radial DI box and using the cabinet to take the load?

Im not that experienced when it comes to creating profiles but i ran a little test and am curious as to what other think may be the best practice when it comes to my two comparisons ive made.

I made two Direct profiles of my AC30 head Top Bost High channel. Running the out into my Suhr reactive load and sending the unfiltered direct tone out to the kemper for the profile.

One i set the gain/volume at 5 and the other profile i set it full out, all other knobs at noon. I then took both profilesn I had made and set up two presets with the same IR and same amp settings. They sound very similar but i definitely notice some small variations. I think i actually prefer the profile i made with the gain set on 5.

I usually run this amp with the gain around the halfway mark. Would it be more accurate to create a profile with the gain set closer to where i usually run the amp live? I did notice that the default definition settings of the full gain profile was a little lower. 1.8 definition on the full gain profile vs 3.8 on the halfway gain profile.

Which do you think would be the more accurate profile between these two?

Quote from Wheresthedug

The only flaw in the process which drives me crazy is the fact the Kemper allows multiple Rigs to have the same name. Therefore, you now have two DIFFERENT profiles with the name of the original Rig unless you manually renamed the new profile when saving. You can tell them apart by looking at the date/time stamp on each but it would be much better if Kemper used the standard computer methodology of not allowing identical names and simply added a unique identifier to the new rig ( e.g. Reference Rig_1)

This is the part that is causing issues. Sometimes my new profile with the same name (or even if i change the name) is overwriting the sound on the previous preset. Both have the same name with the newly profiled sound. Thats why im being forced to copy and paste a dummy profile to use as the browser profile before the profile process is started. UNless i do this, the previous profile "sometimes" gets overwritten. Not only the name and tags but the entire sound that was profiled. Im now thinking this may have been a bug at one point. Ive updated the firmware and have been using this workaround for a while now to maybe the bug was fixed and im just not aware of it since im not risking overwriting the preset.

Quote from Edward Dixon

I've only profiled 5 of my amps and never had this problem except on my first profile where I did not edit the name first and saved a profile with the same name as the profile I had loaded but I could tell the difference between the new and old profiles profiles by the date. I ended up with 2 profiles with the same name but different dates. The original profile was never overwritten. I'm not sure from what you have written what it is you are doing. Maybe you could video your process and we might see where the error, if any, is.

its weird. if i dont change the name i get two profiles with the same name but sometimes the second overwrites the first and both are the same sound and sometimes they are the two different profiles

The problem im having is that im trying to make multiple profiiles of the same amp with 99% similar tags and just change for example the gain level on each. therefore initially i was trying to choose the previously made profile and then create a new profile from that to save the hassle of having to re enter all the tag info. But eventually i figured out that the profiles were randomly getting overwritten. I dont know if this is a bug or not. Thats why im looking for clarification. I guess ill just stick with the workaround process for now.
