Kemper or Axe II - Owners input please

[JerEvil]

Maroon 5, hahaha, lame...

Dude don't bring that burger shit here too! Lol.

For $750 - $1200 (for me, not the band) for two 45 minute sets, I'll be as lame as Erkle.

Owned an axe standard and ultra. Cool devices but I spent the majority of the time turning knobs and getting aggravated with it.

Bought an unpowered kemper when I was recording my album last year and it was probably the best gear purchase I've ever made. Now I did sell it, only because I wasn't planning on doing any more recording for the foreseeable future but I always said I'd own another some day. That day came much sooner than I thought as I have a powered head coming this week. I plan on using with a traditional guitar cab because I prefer feeling that air move behind me. I tried an alto 112 and it was pretty uninspiring but direct it sounds amazing.

Right on. I do a LOT of recording and lean towards the Kemper as I like everything I've heard from it. I have an Alto as well and don't dig it. Just got an ISP Stealth power amp. It sounds infinitely better than with my Splawn 2x12 and Eleven Rack. I just ordered a Jet City USA made 1x12 with a V30 for $219 new that I'll be using with it.

One difference to consider is Kemper appears to be a more professional company. The guy behind the Axe FX has had a number of online tantrums and meltdowns. That is hardly the type of behavior one would expect from a company that produces high-end electronics.

Certainly, that does not affect the quality of the unit. However, I have learned that small companies are much like women. In other words, avoid the one's attracted to drama. If purchasing an Axe FX represents a major expenditure for you, then you may want to consider the behavior of the unit's designer. I'm not sure you can trust a company to stick around or provide needed support and service when the person in charge behaves in such an erratic manner.

The constant updates and the issue with having to rebuild presets each time could become annoying.

Additionally, many users report noise issues with the Axe FX II when they use it in a 4CM configuration. That was the deal breaker for me. Even the Digitech GSP-1101 integrates quietly into 4CM settings based around high gain amps. Why does the Fractal unit require using "humbuster" cables and/or sending the unit back for modifications that will reduce its noise level?

Funny but I think Digitech is the only company to get the 4CM thing right. The RP1000 while limited, works in 4CM without the noise and endless tweaking to get it right.

I just picked up a used GSP1101 and I totally agree. Ive owned an AxeFX Standard, Ultra, and a 2 but I've never messed with the XL++++++2 Electric Bogaloo. I always go 4CM and I had noise issues with the 2 the most but the Ultra and Standard were just OK as far as not adding noise. For the life of me I couldn't understand why a Line6 M13 or POD HD could get much better results noise wise than a unit almost four times the cost. The Digitech's FX are very nice and it's even better at at being dead quiet at $300 used. I actually think with 3rd party IRs the GSP's modeling is pretty good. It's better than the all other modelers that I've had except the Kemper.

That's the main reason I'll never go back to owning an AxeFX product and yeah it doesn't help that the owner of the company acts so immature.... let alone the knee jerk zealots in the community of users.

Id say an axefx or a kemper with a good tube amp is the way to go
Try both and see which one suit your needs the best
As long as you pair them with a good tube poweramp and a guitar cab

You can get good tones out of both box

I'm an axefx guy since 2011 but i could have chosen a kemper at that time if it was available..

I can't justify owning both units

Tube amps will have a huge impact on your sound with the Kemper. Personally , I did not think the KPA sounded very good with a tube power amp and a guitar speaker cab.. The Kemper is supposed to give a "finished product" type of sound, and the best way to get that is with the FRFR speakers. Tube amps and guitar speaker cabs will color the sound quite a bit. I am not saying you cannot do it and get a great sound, I just prefer the FRFR method for my monitor and go direct to FOH for my sound out front. YMMV

I used a CLR for a while and didn't jive with it.

So I bit the bullet and bought a KPA about a month ago and I've been profiling the shit out of my amps and some borrowed amps and I will say this... The unit is absolutely dead-on to a miked up cab as far as I can tell. The amazing part is it's not just the sound, but the actual feel of the amp. Alien technology I sez! I'd go so far as to say that the profiled amps sound BETTER to me than the real thing! They sound more polished and professional. They also sit in a mix with absolutely no post-processing. That said, it is a very funny piece of gear in that it's got a lot going on and requires the individual to be fairly adept at miking up cabinets to really get the most out of the unit, which is why there's a 3rd party profile industry that seems to be sprouting up around it. Now I bought the KPA with the full intention of never needing an amp again but I found the profiles it came with to be lack-luster and many of the pro and community-shared profiles were not to my liking either so I went ahead and started profiling. Much to my surprise I enjoy the process of profiling and it's made me think of getting my hands on other amps to add to my profile collection.

As far as the comparison to the Axe Fx, I don't own the Axe but I can say that some of the best sounding profiles I've found were the ones that were profiled FROM the Axe FX (yes you can do that ). So there is definitely no compromise when it comes to sound quality between these two units.

Ultimately I think they're both great at what they do but they seem to serve a different purpose. The Axe FX is a preamp and is basically a sound-generating unit. The KPA steals the soul of whatever you want to run it through. When I tell you it's uncanny it really is. I was blown away by the profiling process and the tweaking that can be done afterwards.

Which brings me to another point...
Tweaking EQ, gain etc. is not quite like tweaking controls on a modeler or emulation of an amp. It's also not quite like tweaking the source amp. I would equate it more to post-processing than anything else. While it offers a degree of flexibility, it's designed to be more of a refining tool rather than sound-generating tool. For example, tweaking the amp profile's EQ too drastically, would yield an unnatural sound. While small adjustments really take the profile to the next level while retaining its integrity. Don't get me started on tweaking the actual FEEL of the amp. It's like magic. Adjusting the power sagging and clarity to make the profile more or less in-your-face or to make it softer to play is really cool.

Anyway... long winded post here but I figured I'd give people my overall impression.

Yeah the 11R is a good unit. It's cool because it's all self-contained and doubles as a recording interface. But the difference between the KPA and the 11R is startling (with that price difference between these two units it's totally understandable). I had them both and a/b'd them back to back.. The difference is laughable...

 

[BYTOR]

I love all you guys jumping on the digi-train for playing live & of course recording.........only gonna see more & more of this as the AxeFx/Kemper level of tone/effects/routing becomes commonplace in many different digital products....... Just starting to sound too good & too convenient to ignore.....

Eventually getting this level(and better) in products $500-$1000, will relegate heavy 1 to 2 trick pony tube amps & big pedalboards to the strictly die-hards!

[PBGas]

I really like both products. My friend has an AxeFX II and it sounds great through his CLR. I have had 3 to date.....lol.....over the last 3 years. I had the lunchbox when it first came out but sold it due to not having a working footboard solution and Kemper bailing on the poweramp upgrade. I then purchased a powered rack that gave me some issues with shutting down several times. I brought it back to the retailer who sent it back to the distributor. I don't know where it ended up. I now have a non-powered rack and it works great. At times, I wish I had have ordered another powered-rack to give me the option of running a regular cab without an external power amp but I've really gotten used to the FRFR sounds.

I really like where Kemper is going with their stuff and the fact that they aren't putting out new hardware every 12 months. I also like the fact that I can profile an amp and enjoy it without having to lug it around. The new footboard will be a great addition.

Decided on the Kemper. Very much looking forward to getting it. Did you find it relatively easy to get profiles you are happy with? I want my Quickrod profiled first and foremost.

Thanks man!
I haven't been happy with any of the free profiles I've tried.. But your mileage may vary. There's like 5400+ profiles on there. It's impossible to try all of them lol

 

[crankyrayhanky]

^ I actually have tried them all. There's oodles of solid profiles on the Rig Manager. Super easy to preview (unlike the early days), so even though there's crap it takes a second to move on. Looking at your sig reminds me of the Splawn profiles, somebody uploaded a slew of profiles on that amp with all the gears and other variables. Plenty of 5150s & Rectos too.
"Crap" profiles could also be a signal chain mismatch; ie a super strat guitar tweaked with BK Juggernauts may or may not sound as great with a LP Burstbucker setup.

My friend had the Kemper on a Mesa 2:90 through 4x12's and I thought it sounded like shit. But, we HAD to be doing something wrong because I hear clips and videos where it sounds great. I know we had the cab sims off though so I'm not sure what we did wrong. I had an Axe standard on a Mesa 2:90 and that did sound pretty damm good to me.

Once I get it I'll definitely be combing through those. I've had s few friends send me profiles they have posted that sound amazing so I should have a pretty good basis for comparison. Is there any kind of editor for the Kempet yet? Is it not necessary?
