    Hi. We used either the V30s or the Greenbacks, but not both together. You can see which were used for each profile by looking at the profile details in Rig Manager or on the Kemper (I forget exactly how to do that on the Kemper).


    "M" stands for merged profile. A "-2" or "-3" is a variation of the amp at a particular gain setting, usually a different speaker, different mic, different EQ, etc.


    We use a DI box supplied to us by Kemper. It looks like a tiny version of the lunch pail Kemper. :-) It works well and seems to only color the sound slightly.

    Merged profiling seems to be the most accurate, relative to the studio profiles, at higher gain settings (our High, VHi, and Max profiles). We rarely have trouble getting a good merged profile under these conditions.

    Merged profiling can be rather frustrating at low and medium gain levels (our Cln, Low and Med profiles). The Kemper sometimes simply won't capture an accurate merged profile at low or medium gain levels, and you end up with something which doesn't sound at all like the studio profile. Sometimes it works great. Sometimes it doesn't. It's hard to predict when it'll be a problem and when it won't.

    This is why we still include studio profiles in all of our packs, as they are the most accurate in capturing the sound of the amp.

    One way we've found to get merged profiles to work at low and medium gain settings is to reduce treble and presence a bit on the amp. Sometimes this does the trick. Unfortunately, that means the merged and studio profiles are more different sounding than they would have otherwise been. We'll then adjust the merged profile after the fact, but there will still be some differences.


    Hey Kemper Fans,

    We're happy to announce the availability of a new profile pack for the Kemper Profiling Amplifier -- the "800" Pack. These profiles seek to recreate the sound of an original 1982 Marshall 100W JCM 800 head.

    Speakers Used During the Profiling Process: Celestion Vintage 30 or 25W Greenback

    Min to Max Gain Range (Scale: 0 to 10): 0 to 8

    Profile Type: Studio, Merged

    Comments: If you want the sound which has probably been used on more rock recordings than any other, then this is your pack. More gain and low end available than most of our other British-inspired packs. This pack will give you a fantastic platform for any style of music which requires light through heavy overdrive.

    Marshall JCM800 2203 Background Info: Introduced in 1981, the JCM 800 line became the bedrock amp for 80's rock guitar tone. The name comes from Jim Marshall's initials, "J.C.M.", coupled with the meaningless "800" from the number plate on his car. The amp uses 3 12AX7 preamp tubes and 4 EL34's in the power section, and produces more preamp gain than previous Marshall offerings.

    Profiles are available at

    Thanks, and let us know what you think!

    Hey Kemper Fans,

    We're happy to announce the availability of a new profile pack for the Kemper Profiling Amplifier -- the "Boston" Pack. These profiles mark the third pack in our Legendary Tones series (joining the Brown Sound and DC/AC Packs), and seek to recreate the sounds heard on the recordings of the rock band Boston.

    Amps Used During the Profiling Process: '68 Marshall Super Lead, Rockman Sustainor

    Speakers Used During the Profiling Process: Celestion 25W Greenback

    Min to Max Gain Range (Scale: 0 to 10): 0 to 8

    Profile Type: Studio, Merged ('76 and '78 profiles only). We were not able to produce merged versions of profiles created using the Rockman Sustainor ('86 and '02 profiles), as it includes speaker emulation in the signal path.

    Comments: The tones heard in this pack are truly legendary and instantly recognizable. As we found out, they can also be extremely difficult to obtain. The lead tones and clean tones are easily usable outside of playing Boston covers, as are the Marshall-based '76 and '78 rhythm tones. If you're in a cover band with a great singer, a fan of the band Boston, or just love these distinct guitar tones, you'll love this pack.

    Profile Naming Decoder:
    '76 = Emulates tones heard on the self-titled Boston album, released in 1976
    '78 = Emulates tones heard on the second Boston album, Don't Look Back, released in 1978
    '86 = Emulates tones heard on the third Boston album, Third Stage, released in 1986
    '02 = Emulates tones heard on the 2002 album, Corporate America

    Profiles available here:…-Pack-BOSTON-20170722.htm

    All guitar tones heard on the following demo were recorded with a Kemper using the Boston Pack. Some tracks include drums/bass/vocal backing tracks found on YouTube.

    Thanks guys. Appreciate the support.

    We do free upgrades if you bought the previous pack within a month or so before the new one came out.

    Otherwise, we think it's fair to charge for the upgrade pack for two reasons:

    1) We think the old packs were a good value
    2) Putting together a good-sounding pack takes a ton of time and a financial investment on our part

    The Everything Pack is also heavily discounted over buying individual packs (36% discount).

    If someone bought Van Halen I in 1978, I don't think Van Halen would have been cool with giving that person all the albums after that for free. :-)

    Anyway, we greatly appreciate your support and we'll keep putting out profiles that we hope you guys will enjoy.


    Hey Kemper Fans,

    We're happy to announce the availability of a new profile pack for the Kemper Profiling Amplifier -- the "Uber" Pack (30 profiles). These profiles seek to recreate the sound of a Bogner Uberschall Twin Jet head.

    [Blocked Image: https://ci4.googleusercontent.…92372e2ca36e51c/image/png]

    Speakers Used During the Profiling Process: Celestion Vintage 30

    Min to Max Gain Range (Scale: 0 to 10): 0 to 9

    Profile Type: Studio, Merged

    I love using these profiles with drop tunings. We created profiles with differing levels of bass response to fit a variety of tonal needs. These profiles can get heavy! The Ch1 profiles can also be crunchy and sweet.

    Bogner Uberschall Twin Jet Background Info: The name TWIN JET refers to having two powerful gain channels on tap versus the more traditional clean and gain channel configuration of the standard Uberschall. This new gain structure offers a clean channel that can be dialed in as a second gain channel with a different voicing than the high gain channel.

    Thanks, and let us know what you think!

    I think the offset 45 is an interesting option. Tempting! I like the demo. How different from the older 45?

    The Offset '45 is based off the original Marshall from 1962, and sounds like a mix of a Fender Bassman and a later Plexi. More vintage than the regular '45 pack. It was also profiled using Celestion Alnico speakers (as well as our 25W Greenbacks), which have a different flavor to them.


    Out of interest is there then a way of seeing on the site which are the newer packs?

    We currently don't have a listing of the most recent packs, but I'll list them here for you (with the most recent first):

    Modern 30
    Offset '45
    Tangerine 30
    Medium-Power Blackface #3
    Brown Sound
    Low-Power Tweed #2
    Stevens 100
    Medium-Power Blackface #2
    High-Power Tweed
    V Pack
    Medium-Power Blackface


    Glad you're liking the profiles! Our profiling techniques are constantly evolving, so the profiles will sound a bit (or a lot) different than previous packs. We think for the better. :-)

    Played with it a bit more and found that this pack nails many of Paul Kossoffs tones as well. Was playing along to "Free live" and the H2H Lead Profile was spot on to Koss' Sound at the Sunderland Mayfair gig without any tweaking.

    I used a couple of Andy's Marshalls for those sounds before and got close either, but they had to be tweaked a bit more. Your's are right there from the beginning, given you use a nice Les Paul with PAF-like PUs.

    May I ask why you leave the EQ-stack on "post amp"? Was that intentionally? I found switching it to "pre" makes the tonestack behave more like a real Marshall would do. It doesn't do much EQ-wise but you can shape the distortion character a bit which I like on old Marshalls.

    Thanks! Seems we use similar pickups, which makes the profiles "tweak free". :-)

    I've never actually tried setting the EQ-stack to be "pre". I've always used it as a post-profile "mastering" tool rather than trying to emulate the functionality of the real tone stack of a Marshall. I'll have to try it out.
