    I wish. No floor unit and lack of a solid editor was the reason I have migrated to an AX8. Haven't touched either of my Kempers since last August, matter of fact literally just sold my rack unit. If they would come out with a player floor unit and a good editor, I'd buy it in a second.

    +1 for the KPA editor!

    I almost never use Rig Manager, for the simple reason I don't keep a hecka lot profiles on my KPA in order to speed up boot time. But an editor would be something much more useful to me. Just my druthers.

    Fer chrissakes, my Amplifire has an editor! It ain't perfect, has a couple bugs, but it's sure a lot easier than going through the panel knobs and buttons.

    And there is a 3rd party available for my GR-55 which works very well, again some bugs but nothing serious. So a third party solution would be fine as well. I guess I'll have to try the Toaster editor out when it works with OS 4.0.2....

    Apparently Roland and Kemper have similar mindsets about editors...Just kidding! No need to flame me on that!

    Click HERE to hear our new Lonestar single featuring Kemper tones. The solo starts around 2:00. I'm using my AC30TB profile for rhythm parts and my '70 Marshall JMP 20w for the solo. Thanks for listening! If anyone knows how to embed the video, that'd be great. Thanks!

    That sounds GREAT, Michael!! Your phrasing is really tasty, and your playing is outstanding - as always! And the tone, um-mm, omigish... that is the reason my MBritt profiles are pretty much my go-to for any given need.

    I cannot comprehend how anyone can say that the Kemper sounds "digital". In some ways, it surpasses the sound and capabilities of a tube amp, and I was (and still am) a tube amp fan, albeit one whose eyes have been opened to the possibilities inherent in digital modeling which allow a machine to take the best qualities of a tube amp, remove the undesired, unnecessary, and unusable bits, and distill it into a small, portable form suitable for recording and performance. It does cost... but you get what you pay for.

    I was going around with someone about it this week who uses an Eleven Rack he purchased for $200 and who insisted that a Kemper (or any digital modeler) could never sound as good as a tube amp. irregardless of the fact that he had never even heard a KPA. His judgment was based upon the "...harsh digital sound" of his 11 Rack, and his mind had already been made up, in fact he stated that digital modeling would "never sound as good as a tube amp". I finally gave up. No use wasting any more time on him. I wished him good luck and Godspeed. What else to do?

    That is pretty much what I used for this live performance of Jump (KPA Rack with DXR10, monitor out to DXR10, main out R to PA, unlinked at about -15 dB or so), using the bundled Gundy Brown Sound EVH factory rig... audio quality not that hot, as it was recorded on a little handheld camera. BTW this was the first night out with the DXR10, I received many compliments on my tone that evening, including from our bassist...

    FWIW, I contacted B&O regarding the Icepower 1000A bandwidth. It is not an error in the datasheet. Below is the exact communication from their rep, Paul Meister. Take it as you will.


    "Hi Nicholas,Your email was forwarded over to me from B&O. Thanks for reaching out. The 1000A was designed (15 years ago) with only low frequency applications in mind. Therefore there was no need to go above 3khz. When the 1000ASP was designed a couple of years later, they thought that they would get more full range applications, so it was designed up to 20khz and everything since then and going forward is full bandwidth.Thanks and regards,

    (My inquiry to B&O)
    I am writing with regard to the Icepower 1000A power amplifier specifications. I would like to check and see if the typical -3dB bandwidth (at 4 ohm loading) value of 3 kHz, as given in the data sheet (see highlighted line on page 5 of attachment) is a correct value? It seems on the low side. Similar products, such as the 1000ASP, have a BW of greater than 20 kHz. Also, are there any - 3dB BW measurements at 8 ohm loading for the 1000A? Any errata sheets for the data sheet? Thanks for the help!"


    Yep, the 3 kHz BW is something from the old AM tube radio era. We're talking pre-Armstrong here! :-)

    I was for certain not looking at the phase response, it was definitely the frequency response curve. The 1000A has a 3 dB BW of 3 kHz, see page 6 of the 1000A datasheet (http://www.icepower.bang-olufs…ons/icepower1000adata.pdf). Top curve is amplitude response. It also states this value in the table on page 5, Typical value of the Upper Bandwidth Limit @ Rload = 4 ohm is 3 kHz. According to the curves, the 4 ohm/8ohm/16 ohm responses are almost identical.

    The Icepower 1000ASP has a 3 dB BW of approx 30 kHz. This is as shown on page 9 pf v1.5 datasheet (http://www.icepower.bang-olufs…s/icepower1000aspdata.pdf). This agrees with the 30 kHz value.

    It comes down to what is in there. I haven't wanted to open it up and look at what is inside, I'm afraid to void the warranty. Can you please tell me which one it is? That will put it to rest.


    Ah hah - thanks, Timo! Yep, I know, v1.1 doesn't support it, that's why my 1.1 floorboard doesn't show it. But since the KPA needs to be in that mode first, I'm not clear on why it changed. The v1.3 floorboard worked the same as v1.1 since last November and then suddenly during that rehearsal it changed modes, so the setting must have changed for some reason in the KPA, as I did not mess with the System settings at all at the time. It was a very noisy environment electrically speaking, so perhaps that had something to do with it. Our keys guy had weird stuff happening with his status lights on his boards while we were there, so the poor electrical quality may have been the cause after all. I was even using a Furman filtered strip and, while it reduced the noise quite a bit, it was still there. Maybe I should run the KPA on a battery-backed-up UPS when I rehearse there in the future. :-)

    Anyway, thanks for pointing it out to me. I think I'll stay in the mode for a while and see how it works out, it may actually have been a serendipitous occurrence. Thanks again!!

    I have been using my FCB1010 with the U4K v1.3 PROM for some time. It has always worked whenever I switched banlks in Performance mode by going to the last slot selected. Yesterday at rehearsal for some reason it seems to have gone into "performance pre-selection mode", as described by the U4K FW rev history (from the U4K website):

    "v.1.3 (25/02/2014)
    -> Press switches 1+2 during startup to activate stomp config mode (this avoids interference between stomp config activation and beat scanner activation)
    -> Support for beat scanner activation by keeping the tempo switch pressed (this needed a change in transmitted MIDI messages)
    -> Support for "performance pre-selection". In this mode, while browsing through performances their index is displayed on the FCB1010 display and
    the slot LEDs are blinking. Only after clicking a slot switch the performance is activated. When clicking no slot switch within a certain time,
    the previously active performance and slot are activated again.

    It now seems to be in this mode permanently, when I switch banks all 5 slot LEDs flash together 8 times and the KPA screen is grayed out, and when I select a slot it goes right to it. All that is well and good, and I think it may actually be useful, but I don't know how I managed to put it into this mode, and I would like to know how to get in and out of the mode. I did the FCB1010 U4K factory default reser but no difference, I also did a backup restore on the KPA from my last backup, and it still does it. If it is a soft switch in the Kemper I don't seem to be able to find it, I have looked through the addendi and the manuals and didn't spot anything about that mode.. My FCB1010 with v1.1 does not show this behavior, and according to the FW history notes it never will. Anyway, I will use the mode now, especially as I have no choice, but if anyone can tell me how to control which mode it is in it would be appreciated. Thanks!

    Hopefully this post will not upset too many Power Head fans, but I would like to post my observations about the Power Head with the Icepower 1000A amplifier (and the Power Rack as well I assume, since they use the same power amplifier) .

    I purchased my first KPA, a Power Head toaster model (as an Xmas present to myself) back in Dec 2013. My intention was to use it as a standalone amplifier to drive a cab and eliminate my pedalboard and boat-anchor tube amp. Since I bought it, I have had many comments from fellow bandmates (in the bands I have been in or am in) regarding how dark the sound was from the cab, no high end. Going through the main out direct to the PA sounded nice and sparkly all the time, but the cab sound was dark no matter what I did. I was using a Weber Vintage speaker at the time in an old Lopoline 1X12 convertible cab, as well as some Carvin 2X12 cabs.

    I figured the issue was the speaker. I went to a Beyma 12GA50 in my little ol' Lopoline 1X12 cab, no difference. Then I bought a Mission Engineering Gemini 1-P passive FRFR cab, but still no substantive difference. Weird. Then, for grins and chuckles, I tried running the toaster monitor out into my Quilter Tone Block 200 into the Gemini 1-P, and it really opened it up. I went back and looked at the Icepower 1000A -3dB upper bandwidth spec, it's only 3 kHz (albeit at 4 ohms, likely a little higher at 8 ohms). The Quilter Tone Block 200 has an upper -3dB BW limit of 10 kHz (I know, I emailed Quilter Labs about it, Pat Quilter answered me personally and told me the bandwidth). That explained the more sparkly and open sound, it was getting close to the direct-through-PA tone I was experiencing.

    I then went and purchased a Matrix GT800FX, which has an upper -3dB BW of 24 kHz, and I now enjoy even more high-end goodness out of my rig. It sounds darned near just like the PA tone. My bandmates have stopped complaining about the blanket-over-the-amp tone from my cab, another benefit of higher bandwidth.

    I have purchased a KPA unpowered rack unit and intend to use that with the GT800FX for live use, and I'll use the toaster with the Quilter for rehearsals and recording. So all's well that ends well.

    If I had known then what I know now, I would not have purchased the Powerhead, I would have just bought the unpowered version and used an external power amp with wider BW for driving a cab, as well as just biting the bullet and buying a good FRFR cab. I know, I know - if I didn't like the tone, why didn't I just skip the cab altogether and go with the PA and some monitors maybe some DXR10s? Well, I LIKE having a cab behind (or sometimes in front of) me interacting with the guitar, and I like the traditional cab look. Just my druthers. Anyway, I thought I should share the results of my experience with you all, it may help someone else shorten their path to tonal Nirvana with their Kemper. .

    Thanks Gianfranco. Wasn't trying to diss you, but I have been agonizing a bit over it and was worried that a long enough high current transient at 4 ohms will damage the amp, so I have chickened out, have tried a Quilter 200 running two 8 ohm cabs and it works OK, but that is why I inquired about buying one of your amps for the Kemper, less gear I have to schlep to a gig the better! Please let me know when they become available again.

    Many thanks! - Nick

    FWIW... I have been using pretty much exclusively Mr. Britt's profiles since I purchased packs 1 and 2 a few months ago. I run a Powerhead into one of several cab types: (1) an old 1X12 Lopoline with a Texas Heat in it; (2) an older (2004-ish and well-broken in) Carvin 2X12 open-back with the older Carvin 12" guitar speakers in it; and (3) a newer closed back(convertible) Carvin 2X12 with the newer Carvin speakers. They all sound great with the Powerhead, and I have received many accolades on my tone, both with and without augmentation through a PA, as well as quite a few puzzled looks when folks notice my head. More than once I have been asked "where are the tubes?". :-)

    BTW, I tried turning off the cab sims at one rehearsal, but the singer commented that the sound was kinda thin, and would I please correct it. I have not turned them off ever since.

    I tend to use the Dream Weaver profiles a lot, especially the Klon and Timmy profiles for solos. Diezel is great for the heavier stuff, as well as the Bletchleys for the aggressive tones. A couple more here and there that escape me, but overall the tones are excellent. Will be doing some studio recording with the rig next week and am looking forward to that. Thanks again for some great product, Michael!

    I used to use a FR5 as a backup, but found the Fender side was kinda scratchy when you would overdrive it, plus the bottom end would fart out when I would really drive it, supposedly like a real Fender (which I don't recall ever happening in my years of playing though a silverface Bassman), but after I received some negative comments on that "feature" from my band-mates at rehearsal I looked for another solution.

    The Plexi section was actually pretty good (especially with the boost) and provided a pretty fair emulation of Duane's sound at Fillmore East when I tweaked it a bit Also liked the delay, although it would overload a little too quickly. All that being said - if I had a fly gig and had absolutely nothing else available it would be acceptable.

    Here's what it looked like:

    Anyway, I now use it as a backup for my backup, which is the same PT Jr but with some Hotone pedals on it, the same Turbo Tuner and a EB VP Jr volume pedal driving a Quilter Tone Block 200. Sounds pretty good, has a good choice of effects, and gets plenty loud. All I need is the pedalboard and a cab. But it doesn't come close to my Kemper...
