    Manual says it has no influence on distorted profiles. The forums says it only effects clean to mildly distorted profiles (but just the output level), but you can clearly hear it’s changing a distorted profile that has a gain setting of 8. It’s somehow interactive with dist sense and you can alter where the focus is not unlike a mid band eq before the amp. For instance a lower clean sense below 0 with a dist sense above 0 almost scoops the sound a bit or thins it out. It’s not changing the out put volume. It’s changing the focus of the way the guitar hits the amp. You can even have dist sense on 0 and sweep around clean sense and you can clearly hear it affecting the tone, it’s more prominent on some profiles than others but try it on a Sinmix profile or a Big Hairy Profile and you’ll see what I mean.


    Why doesn’t the manual address this?, it’s been 10 plus years. I can provide and EQ match screen shot if necessary.

    Agree, would love to see some improvements to the profiling. If you bring that issue up though you will he met with “it’s perfect”, “no room for improvement”. That arrogance will lead to someone coming up with a better solution. Do I think Quad Cortex is that product? At this stage, no..but it’s in its infancy. If Roland, Line 6 or Fractal come up a capture product given their reach, sharing, clouds and software editors etc, it’s game over.


    The black art of refining the profiles is what kills me. It’s been debated for 10 years on how to refine a profile and the manual covers it with a vague sentence or two. With the Quad eliminating refining, it is a step in the right direction...even tho Kemper claims refining isn’t necessary anymore, I don’t think I’ve ever heard a profile I did that was close enough right off the bat that didn’t need it.

    I tried It both ways. Tried it like the manual says “just play some chords” etc and also tried refining for a long period, also tried it with no refining because supposedly “it gets so close now refining is redundant” lol.


    This isn’t a golden ears type situation, as you can see on my EQ match it’s way off in the low end. After reading this forum it seems most people on here don’t profile their own amps and just buy pro packs. I’m going to contact some of the pro profile sellers and see if they encountered this.


    I’ll also contact support but not sure what they are going to tell me except to “factory reset”.

    I mainly started this to see if anyone was finding more sub bass than the real amp, and apparently a few people on this thread have (as well as others on the forum if you do a search about it).


    If anyone wants to see my amp settings, mic placement or sound files, that Dropbox link I posted earlier is still active.

    I appreciate the help guys, but it might be time to sell this thing. There’s definitely something different. Factory reset and all output eq’s and filters flat, upgraded to latest OS, pure cab unchecked, profiled two different amps (EVH III & JCM 800) with all settings at noon and the amp way below “power amp” saturation levels, tried a load box and a mic (standard SM57 where the cap meets cone).


    Would refining with a bass help?

    I’m tuned to D standard, but I was back in 2015 too and those profiles were close to perfect (same JCM 800, mic and guitar)

    Thanks for the suggestions, yeah I made sure Pure Cab is unchecked (instead of just being “0”) and all EQ’s and filters in the output section is flat.

    Further updates, I tested the load box vs mic’ing and then EQ matched. The mic’ed version is worse than the load box version. It’s adding a ton of extra crap under 100hz.


    I then decided to profile my JCM800, to rule out that it’s just a problem capturing an EVH 5150 III. I didn’t use any pedals and low and behold, that one is also adding more subs than what’s present. Can someone look into this? I’m pretty much ready to sell this thing. It’s one thing if it was always like this, but My profiles from 2015 sound way better on my JCM 800 with the exact same gear.


    Someone told me that own both the stage and the toaster that this problem happens to them only with the toaster but doesn’t appear with the stage. ckemper ??

    I own the rack version.

    Updated to the latest OS, same issue.


    I'd love to resolve this, been loyal to Kemper since I bought it in 2015, Profiled a ton of amps back then (which profiles I still use to this day), Just started up profiling again and the low end accuracy is much different than before. Back then, as others have said, it might have been a little light in the low end, but that was much more useable than it is right now for me. As others have said, really noticeable in palm mutes, sounds like "And Justice For All" speaker woofing Even when its not supposed to haha.

    Hi guys, back home and ran some tests, EQ matching. I'm on OS 8.2.2 DonPetersen .

    Some background on the test:

    1. EVH 5150 III EL34 head into matching 2x12 cab, mic'ed with SM57 in the standard position (Mic placed where the cap meets the cone, standard metal mic'ing). All Knobs at 12 o'clock minus the volume which was set to 10'oclock. Set the resonance on the back to 0, tried it with my "normal setting of about half way up and the subs were completely out of control, this was the only way i could even get the sound to not sound ridiculous.

    2. I used a looping pedal so that all the sound tests were the same material/riff.

    3. I recorded the original amp, then the profiled amped before and after refining. Also included versions where im bouncing back and forth so you can see the difference without changing files. The one that bounces back and forth starts with the Kemper profile, then to the original, and then back again.

    4. I EQ matched pre and post refining. as you can see anything below 100hz is out of wack. Also the high-end is completely diffrent but I mainly notice the sub bass.


    Link the files and screen shots:

    Sorry guys, I’m away till tomorrow, I will provide screen shots of eq matching curves as well as sound samples. It’s consistent every time I profile that there are more subs so it won’t be hard to replicate. As for pushing my load box, I was only on 4 - 4.5 (around like 10:30 on a clock) on the master volume as I found that’s the sweetspot for the sound I’m going for on my 50watt EVH.

    The profiled amp has more subs than the real amp, you can hear it on all systems, including headphones. My concern is because of the complaints of lack of subs they jacked them up in an update. I remember years ago they removed the option for bass boost. Is there something that changed that makes a 5150 III EL34 harder to profile than before? ckemper ?

    The only way I can even reduce them is during the refining phase to place a physical EQ between the amp and the Kemper and cut out everything with a 12db high pass filter above 120hz . Something is going on, I’m very familiar with the Kemper (owned since 2015) and profiled many many amps over the years. As you said, before my only issue was lack of bass, now it’s overboard in the subs.
