Help cleanup digital "hair" on profiles?

    I fully agree, Dean_R.


    One comment to the statement above: the biggest part to get better might not be "excellent equipment". It dont hurt, thats for sure, but decent equipment is now available to all of us. The weak part of the chain is still the user - and especially his ears and fingers. I am not profiling, but there is this fine-tuning at the very last step, no? My assumption here: sloppy playing, i.e. fret noise artifacts by inproper acting fingers may well hurt the process. In addition I watched people going to the amp section and "helping" the matching algorithm with minor tweaking to get a perfect result.


    What I really mean: a so-so guitar with a so-so amp in the hand of a guitar heroe will sound awesome. And a fool with a tool is still a fool.

    Ne travaillez jamais.


  • Hey Dean thanks for your thoughts. Yeah I have watched the Captain and Rob Chapman video before :)


    So I am a long time tube amp user. I have had modelers as well, most recently I bought an Atomic Amplifire about a year ago. So I have both. I am looking for that amp in the room sound and feel I guess. I WANT to be fooled if you would that I am really playing the "X" amp for real. I know to really get that true feel, I would need to play through my 4x12 cab with enough volume, but I also know messing for a year with a current modeler what to expect out of studio monitors too.


    Glad to hear that the profiling can be done w/ half decent knowledge and mic's as I have that and would profile my amps and some of my friends collections if I stick it out.

  • Thanks Spinner. Glad to hear you are / were in the same boat as me! Funny I do really like the sound of the real Friedman BE/ HBE stuff.


    Question - where do I find those 3.x profiles you mention? My unit is running 5.0.3.x . Is there an easy way to search Rig Manager for those profiles you mentioned so I can check them out?

    I cannot find it in RM. Let me see...

    Search for Gundy. In general: the rigs on that page are technically on the good side. Its a matter of tatse, of course.


    Then: Kemper Amps (author) - Voice Ace Thirty (profile name) - its my vintage crunch favourite or slight breakup when strumming.

  • My 5 inch studio monitors at my man's cave if I'm sitting in the proper point in the triangle push a little air around my face that I can feel whenever I play loud. :D

    Pure cab is intended to get you closer to the amp in the room. It to a certain degree removes the microphone from the cabinet, so it does remove hair and the high frequencies artifacts that exist when close micing speakers, this would apply if you're using an FRFR system.


    On the other hand if you're considering using real cabinets, the most authentic way would to use merged profiles withe cab disabled, or simply use Direct profiles that are available.


    The third consideration is using the AMP parameters in the Kemper.. "Tube Shape" three and under changes the character towards Preamp and removes power amp character (that's were most of the sizzle and hair come from). Increase tube tube shape above three will bring more power amp distortion character (not the route you want to take if you don't care for sizzle). You can even try "Preamp only profiles", for high gain those are generally very tight and don't have sizzle when pushed hard.

  • I definitely hear the fizz and it's excessive to my ears. You've got a lot of high-end energy going on at and above 8kHz, which can be tamed using a low pass filter. If you're getting this on most profiles, you could try adjusting the height of your guitar pickups on one side to increase the low-end or conversely lower the treble side.

  • Seems to me lately that I've been having to significantly turn down the presence of many profiles and up the treble to compensate to get rid of this high frequency fizz. I know we've been told over and over that updates don't effect the tone of profiles, but I don't remember ever having to do this before.

    Hey ColdFrixion,


    It definitely seems profile related or the way that a large % of profiles react to my guitar and monitor setup anyways. Some profiles sound pretty good I've found, but many or most have some sort of issue similar to above. It's actually worse because the compression that Soundcloud does actually helped this sample as live the "ice-picky-ness" of the fizz is even more pronounced and annoying.


    I am working on tweaking some of the Mbritt 70 Marshall profiles and Guidoist JCM 800 profiles to my liking and getting some decent results. Though today on the Mbritt profile when doing some bends I was hearing some weird synthetic sounding pitch modulation that I haven't been able to nail the source of yet, sigh :(. I disabled the stomps and effects and it was still there.


    Getting closer to a "good spot" with this unit, but the struggle continues...

    Interesting to hear that you're hearing a change. I wouldn't know because I started with 5.0.3 with my unit.

  • Well, I solved my high frequency issues after seeing this thread


    https://www.kemper-amps.com/fo…igs-after-upgrading-to-r5


    Basically, downgrade then wipe the flash memory then upgrade back to v5. Any other combination of upgrade/downgrade, flash, etc didn't work for me and I tried them all.

    So being a noob here, what risk do I take doing this?


    Will this procedure work?

    • Take a backup (have to figure that out)
    • Downgrade to 4.x
    • Wipe Flash
    • Upgrade
    • Restore my backup
    • Don't import any new delay presets??? Do I need to find those and delete them before I do my backup?

    Only thing I didn't do on your list was restore the backup, I didn't want any remnants of the prior setup. I just imported all my profiles and cabs after going back up to v5. I have not imported the new delays yet, I'm getting rather fed up with it so I don't want to mess it up again. I've owned this thing for less than a year and I've already sent it back twice for repairs and countless hours of troubleshooting. Actually, I'm willing to bet I've spent more time trying to fix things than playing.


    Hope the fix works for you

  • I'm not sure if this issue depends of the ear fatigue or it's a real problem....
    I have days that I love all my profiles and there are days that all my profiles sound trebly to my ears.....
    I'm pretty sure that the hi gain profiles sound in that way when you pass a gain limit......

    To know whether it's ear fatigue or a real problem, I, in the last two days, played the amps from MY POD HD500 that I'm using as a controller and compared. If you still have an old modeler I suggest you do the same.
    There was definitely a problem in my firmware because the Kemper sounded terrible, no string separation no weight, harsh and muddy!!


    It was depressing that the POD sounded better in comparison, so I confirmed beyond any doubt, that I had an issue. The only unusual thing I did that might have caused this was in Rig Manager I copied over 100 profiles at one time and moved them to "my profiler" folder to send them to the KPA.

    Thanks for posting this, I downgraded to 4 (the release version) and tested, the problem was still there so I deleted all profiles (I have them all backed up) and proceeded to upgrade to 5.03. and KPA was back to normal.


    Next time this happens, I will contact support and hopefully they can isolate the problem, because it's a serious problem if My POD sounds better than the Kemper, not disrespecting the POD HD, but to illustrate that there's no way this was ear fatigue. I chose the KPA for amp modeling comparing it with other very expensive devices and I could hear substantial weight, clarity and muscles that aren't in any other modeler.


    My favorite thing about the Kemper is how it interprets high frequencies in a very musical way, so what some people call fiz or undesirable hair, can be actually part of tube amp sound (Power amp saturation) and others call it desirable sizzle. Some players don't like that and in the Kemper there's a parameter that will help. If you lower tube shape from 3.3 to 3.0, some of that sizzle will be reduced.


    I'm quite relieved that the problem was solved.
    Thanks again.

  • Ok so I think I am going to try this then.


    So what is the proper way to save my profiles and get them back into the Kemper after wiping everything? Do I need to copy them 1 by 1 or something, as doing a restore may bring back the problem? Being a noob, I don't want to reck anything , especially the paid profiles that came w/ the unit.


    Man, this is a sh!tty way to start off my adventure , especially considering the price I paid for this unit :(
