Kemper Profiling Amplifier

I've just read a few articles on The Kemper Profiling Amplifier http://tonymckenzie.com/kemper-amps-review.htm
and wondered what our gnx users views are on it.
a bit pricey,but so were the gnx's when they came out.
It seems like a super duper amp warp machine with a simplified DIY MFX supermodels button.

  • This is a very cool unit. Keep an open mind to its looks. There is another company Matrix also working on an amplification unit that fits in the rear panel.

    Costly items for sure. IMO this one is a contender to seriously compete with other higher end modeling preamps.

    None of this stuff is in the budget ballpark of GNX RP or other all in one sub $500 processor units.

    FWIW that market is pretty refined and saturated so I don't think you'll see that many other high end competitors. For mass produced products, there's more revenue in the sub $500 market than anywhere else.
  • so...?anyone find any comparisons on the GNX4 vs the Kemper online?
    Not the DAW type units vs Kemper etc.
    Sure..I understand the budget vs high end bracket of technology/components/build etc etc
    also the fundamental differences of the processing etc etc
    Im talking about the result coming out the L/R channels....
    Is there really a huge difference?
    like running both items thru a normal PA or headphones setup..A/B'ing the units against the MFX's
    Or is it another mp3 debate about 192 vs 254 vs 320 vs Lossless thing ?
    You know? really?for the average muso with a simple amp/pa setup ?...not for the anal gear geeks,engineers or rich dudes etc etc?
  • Kemper is an amazing piece of equipment. One of the local studios has had one for a while. It has more high freq shimmer to it than most modeling units. I think modelers cut freq's to reduce the levels of hf noise or any aliasing produced from the hardware itself. The impulse response method and variants of that have been around now for quite a few years.

    When profiling, the cab, the mic, etc is all captured at once. Gives the unit a more realistic dynamic.

    Hats off to the designer. Amazing product, and it seems the other high end competition is attempting similar feature sets in their unit.

    These units are not cheap. Impossible to compare their hardware to that of modelers costing less than 5 bills. I'm not sure modeling can have a mid level unit to these either. The DSP's are not cheap nor are the other components and board designs.

    You really can't fairly compare or contrast the units on sound or performance. The spec is quite high and so is the price. GNX4 at its very modest price is quite the performers tool.
  • Totally agree,but,on a metal perspective,i recently had a chance to try one out,i chopped along to a few high gain ones,twiddled the eq's and found a few better than others,but none were over the top that wouldve made me consider starting to save up the coin needed for one.
    Both on headphones or pa,it sounded very good,but it still lacked that chunky tube splutter from a real tube amp.
    Ive seen some sell for $1500 on ebay,but untill they drop to a pocket friendly price,i think my gnx4 is more than adequate to do the job for now.
  • You have to consider the process. Modelers are made to sound like amps in a recorded aspect as well. This can include gain staging. Kemper is going to catch a profile of the amp and cab. Some of their users, some with professional studios have extended that process to using studio preamps, multiple micing positions mixed and output to the Kemper for the final profile.

    For many from the amp world, the factory stuff is as amp quality. For recording and live players, the amplification of these and other modelers are a tougher comparison. Most enjoying modeling have basically gotten used to the fuller range amplification. For one its just more accommodating to speaker impulses. Guitar cabs can yield way too many variants and workarounds.

    When recording, the sounds we often hear are stages of gain, panning etc. Listen to a lot of your artists favorite dry amp tracks. You get a better idea of gain staging.

    That said, yes I too agree GNX4 is a unit with staying power compared to the investment required for the more complex modeling and profiling rigs.
  • totally true.
    I doubt anyone with any modeller or kemper is going to get a metal sound as good as Nuclear Blast,Century Media and Metal Blade labels bands or the Abyss Studio or Sunlight Studio sounds,as i think its all in the power of the engineer in the finished product...that is the key..besides having the chops..LOL
    cheers
  • Gain staging. You can have 4 tracks of guitars at -20db and require a limiter on your guitar ch mix bus or output.

    When I've recorded metal players I usually record a fairly light gain to go with the heavier gain. Heavy gain tends to thin out the mix, so you back that up with a more milder track. Add bass and you fill things in nicely.

    Its a similar process with micing cabs. They'll get the harsher sound close mic and about a foot away get the cab presence on a ribbon, and maybe use a condenser mic about 3 feet from the cab to pick up he room elements. Very much similar to micing up drums using additional ambient mics.
