For me (and it is just my personal choice), it becomes a non starter as soon as I see it powered by a power adaptor instead of an IEC mains connector.

As a mere mortal, playing guitar for fun in pubs and clubs, I still find this stuff amazing...
My band used to cover Cold Sweat so live that song and great to see Darren on keys, still can't believe he was in Thin Lizzy!
Such a great keyboard player. He was so young and so talented when he did this Lizzy Thunder And Lightening album and the Renegade album before it. Angel Of Death is still amazing to listen to.

Sounds very good, Vinny
Reminds me a bit of "Mr. Mister" .......Cheers !
Thanks. This song and the rest of our first album album was mixed and engineered by Mike Shipley who also mixed the Kyrie single and I think he might have also mixed that Welcome To The Real World album too.

Yep, Darren Wharton and you always on my radar with Dare... I like this one from the early years a lot!
Thank you. Yes, that was our first single and video from our debut A&M album Out Of The Silence in 1988.
Quite literally a whole life time ago. 😂I was only 22 when we started this album and had my 23rd birthday during the recording.
The girl in this video went on to play Shelly in Twin Peaks. -
Is it 40 years ago already? Wow, time flies. Still so fresh and striking what Lynott & the gang deliver here. One of my alltime favorites since then
My bands singer is playing keyboards in this video.

I know, but it still needs a power cable for the power supply. Just call me OCD 🤣
I don’t know what the Lehle takes but I have been using a Volto to power my Shure GLX-D16 on my Kemper Stage pedal board. In fact, I have two of the Volto (they are the last green version they brought out and the second is a backup).
While it’s powering that Shure digital receiver, I am getting about 5 to 6 hours out of the Volto.
They are supposed to be bringing their new version of the Volto out but it’s been delayed by over a year already.Great little problem solvers. I only used the Volto’s as I don’t want any wall warts onstage.
I would imagine with something that is drawing much less milliamps, you would get many more hours out of a charged up Volto. -
I agree 100%. Just trying to offer solutions until Kemper decides it is an issue and addresses it.
I also like to try and offer solutions for people landing here from a Google search with similar concerns.
Yes, I understand that.
I have played guitar on well over 30 big label released albums since 1988.
Worked with Mike Shipley, Larry Klein, Mike Stone, Keith Olsen. I know the workarounds. It’s not my first rodeo recording or EQ’ing an amp or getting a guitar sound in the studio or live. .
I don’t really want a workaround in this instance . I am just trying to make Kemper aware of it.

This was also one of the things I do when profiling. I forgot to mention it in my post above.
I may run:
Kemper --> EQ --> Amp --> Mic --> EQ --> KemperI tend to do a lot of experimenting and will have combinations of pre/post or no EQ profiles. Then I tweak them later (after I make 10 or so). I do not have a great amp that I am trying to match. Just garbage amps I am manipulating to sound decent and tweak later in the Kemper.
Since I do not own a decent 4x12 cab, I started using the POST EQ to try and get better tone from the cab. And then I am usually focused more on the mids/highs and do not recall the low reactions to the profile. But I tend to cut at least 3 dB at 80 Hz on the POST EQ almost always. I do this partially just for the IRs created as much as the profiles.
LONG SHOT
Another option might be to boost the bass when doing the REFINE process? Maybe the Kemper will de-emphasize the bass? I cant recall if I have ever done that or not.
VERY LONG SHOT
I recently started running Room EQ Wizard on my cabs to get good IRs of them. And the first thing I noticed is how badly the speakers interfere with each other. This makes me seriously doubt anyone could even get a decent tone with more than one speaker in the vicinity of a mic. If I do not block the sound from the unused speaker it will create phase cancellations all over the place.
I mention this because maybe it has some effect on the profiling process? On the plots I have done, its usually suck outs higher up in frequency. So probably not. I would have to do math to calc the freqs affected by speaker edges being like 4-6" away from each other etc.
I don’t want to start second guessing how to get the bottom end ‘similar’ to the way the amp is already sounding. The amp already sounds great.
I already have sounds out of the amp, cab and mic I am happy with.I know what I ‘can’ try with all sorts or post eq and pre eq. You are completely missing my point.
When we mix an album, we cut low end on a song per song basis.
This is not about that.
It’s about the Kemper adding something that is not originally there on my own amps that I am profiling. -
Vinny isn't comparing what he is hearing in the room with the profile. He is comparing the output through the mike and DAW to the profile so is valid.
I don't profile much myself but a few people are calling this out so it would be good to get some input from Kemper. It also feels like its a more "recent" issue so curious if something has been changed in the profiling process.
Only Kemper can comment on that..
Yes, spot on.
Mic plugged into Kemper and all is monitored through my DAW from the Kemper main outputs.Cab is also being mic’ed in my live room next door to me while I monitor all this from my control room.
The Kemper refine process is fine for me on all other parts of the spectrum, it’s just this added extra low end that is the problem.I can try and use my Focusrite 828 preamp in between the mic and Kemper and use it’s roll off filter to try and lessen what is happening with the Kemper.
But, that doesn’t change the fact that something IS happening in that frequency area while profiling. -
I think people completely forget that the sound where the mic is placed in front of a cab, is what gets profiled. Ofcourse putting your ear where the mic is, will be harmful, but really thatis where the sound of the profile originates. It’s more bassy AND trebly, right there 4-5cm from the speaker.
And yes, the output eqs is the blanket solution, and they fine for that. At least they’ve always done on my setup.
The low end frequency is NOT there on the actual amp. Only on the profile. My ears backed up by a real time frequency analyser show me this.
I already mic up the sweet spot with just the amp hiss and headphones the way I was shown by Keith Olsen back in 1991. Once the sweet spot is found and marked with a China graph pencil, it stays the same unless you change that particular speaker in that cab. This method has served me well ever since.I currently have 10 Marshall 4x12 1960 cabs in my live room. (I plan to sell a lot of these once my profiling session are over and just keep one of each that has a certain set of speakers in them). All my most frequently used 4x12 cabs have been marked for their sweet spots and I have been recording most of these cabs for decades with no problems.
It’s easy to see what I am talking about if you just setup your own favourite stuff where you are happy with the low end. Put a real-time analyser in your daw. Check where your gear is actually rolling off the bottom end. This particular SLO30 is naturally rolling off steeply starting around 80hz and gone by about 60hz. Deep knob is set to zero.Profile your sound. Once the profile comes back, you will see that the profile has now added extra frequencies in almost a straight line that eventually roll off at 20hz.

Interesting topic.
Often when making profiles, I put an EQ pedal before the actual amplifier to reduce the lows going into the amp.
Once the profiles are in the Kemper, I do two things:
- Use a Graphic EQ as 1st stomp (before Noise Gate) to reduce lows and boost mids.
- Set the AMP EQ to pre and use a Studio EQ after the amp.
DUMB GUY OBSERVATIONS
I am currently working on a VST Distortion (I am a noob) and have a High Pass filter before the distortion stages. I often have to set the cutoff frequency as high as 250-300 Hz. No actual data for anyone here to learn from this, I was just amazed how much I had to cut the lows before the gain stages to not be flubby.
I recently added a compressor before gain and this requires even more low end removal before the gain stages.
I added Bass/Treble filters after the gain stages and this seems to bring back the lows (that I just tried to remove) more than I expected. Which reinforces the idea to use the Kemper EQ before the amp. This will remove any effects they are introducing into the sound. The Studio or Graphic EQs will give you more control over the tone. And give you High/Low cuts. The Kemper Bass control is probably similar to mine and could be adding the flub back in.
Filters do not immediately stop frequencies, they have slopes that always let some cut freqs thru. And that is probably why I am seeing these numbers. I probably have selected the wrong types of filters and roll-off slopes also.
Just anecdotal observations. I expected to roll off at maybe 80-100 Hz to get rid of flub. I was way off.
What is going into the Kemper to be profiled is fine.
The problem low frequencies are being added BY the profiling process. -
Why don’t you just go to your output eqs and lower the low end. I did that right from the start.
Because each amp I own has its own distinct roll off point. Each one has different tone stack behaviour and frequency range.
This isn’t a case of applying a band aid ‘fix all’ situation or slapping an EQ across the outputs would even things out.
It needs sorting at source.
It’s currently not profiling the low end accurately. It’s adding something that doesn’t exist on my original amps.The refine process completely ignores the problem.
If it gets sorted out, it’s a win situation for everyone.
-
I have tried a few different amps in my studio now and the profiling is definitely adding frequencies that are not originally going into the Kemper.
Refining ignores it.
Been profiling my Soldano SLO30 this last two weeks. SLO into Marshall 4x12 with G1275 speakers. SM57 back to the Kemper.
The original SLO sound going into the Kemper has a natural roll off starting at 80hz and has rolled off by about 60hz.
The profiles seem to be drawing an almost straight line all the way down to 20hz from 80hz (once the initial peak at 80hz has settled)I did search the forum and noticed a long time ago, low end was added to the profiling process as people were saying it was lacking in this area. Maybe this has now been over compensated for?

Look for a used, well taken care of, pair of MSP5s, they are build like tanks and will last decades. I prefer them over the HS5s
I love Yamaha MSP5’s. Been using them since they were first released.

You guys are on another level and hence probably need this level of sophistication in a backup.
For me, I've never had a failure with the KPA, so just have a sans amp as an "emergency get me through the gig" backup...
With our band, most of the gigs are abroad so I always worry about everything getting there.
Saying that, did one in Sweden a couple of weeks ago and with the way things are with airports and baggage handlers at the moment, I took just one Kemper stage. I took it on the plane with me though inside the green Kemper Stage gig bag.
-
I would even let them run in parallel with an A/B switch before the inputs. If something happen, just switch over to the backup and keep playing
I was talking to Bob Bradshaw about the possibility of him making me a box that would switch guitar signal and XLR’s for front of house with just one switch.
Bob advised me to keep things exactly the way they are as by using another interface, you are then bringing a commonality into the equation that can render both systems to not work.
He advised that an A and B rig should have nothing in common.
Once I thought about it, I tended to agree. -
Oh yeah! sweet setup - I use the GLXD16 as well - very similar to how I will be running
The Volto’s I use work great to power the receiver. They are used to power the GLXD only.
You get at least 5 hours out of each one. I use one for soundcheck and one for the gig.
It gets rid of the wall wart from onstage which isn’t easily replaced at a gig and is always vulnerable to getting crushed by flight cases and monitors being moved.
Then, I have a 50ft backup guitar cable that is on the backup Kemper Stage that can be used with either pedalboard if there is a problem with the wireless.
They are working on a version 4 of the Volto but not available yet and all the ones I use seem to be sold out now.
Anyway, it’s a nice solution for the future if you maybe want to go that way. -
This is my main board and backup board.

If it is critical to see the amp in the Rig name you need to prepare the Rigs that way and load these Rigs. Just loading a preset doesn't do that job.
Yes, I have gathered that now.
Not too keen on how all the tags are setup to be honest. I don’t know exactly what I would do to change it but the way they are now just don’t work for me at all.Also, it would be great to finally support a usb keyboard. I know there is limited use on the classic profiler but the Stage being floor based definitely needs this when profiling…….. or editing all my live tags to represent an amp change.
-
You are providing good reasons why a Rig is more than just an amp. And that is why Rig Author doesn't automatically mirror the amp author. And the cab author could be different anyhow. I suggest you tag your specific Rigs with Rig Author "Vinny" and select the stack via preset or selective browse.
That’s true. 😂
Will investigate.The rigs already have all the correct author (me) etc. But, the name of the rigs are the actual current amp being used in that rig and changing the stack won’t reflect that anymore.
So currently, a rig might be called 3+ SE Rhythm #4 or Boogie Mk3 #6 and that is what it is then tagged as in the rig tags.
It’s just been helpful to do it this way so I know what amp and profile of that amp I am dealing with when browsing all my profiles. But also, when wanting to know what amp I have in a slot of a profile months after I have put it there.
Thanks Burkhard. I do appreciate the help.
