The Resulting Profile - Kemper PROFILER Grundlagen Anleitung

TAKING A PROFILE 17
With completely clean sounds, you don't need to worry about refining the distortion characteristics, so "Refine
Profile" isn't available. If you find that the Profile offers a wider dynamic range, and a higher volume in the tran-
sients compared to the original, the reason is probably that the original sound was, in fact, slightly distorted. This
would have caused a small amount of compression, thereby affecting the result of the profiling process. In such a
case, simply repeat the whole procedure, but without using the "Clean" option.
Power amp tubes generate a different type of overtone structure than preamp tubes. They distort with a harsher
sound, because the negative feedback in the power amp circuit linearizes the tube amplification. This makes the
distortion curve edgier. If you notice in the A/B comparison that the reference amp produces more high frequen-
cy distortion when light distortion is applied, you should set the "Tube shape" parameter to about 9.0, to get the
same behavior from the Profile.

The Resulting Profile

Once you are happy with the result of the profiling, you can store the sound as a new Rig in your Browse Pool.
We highly recommend that you save the Profile before you start modifying its parameters to preserve the original
settings.
Congratulations! You have added a new amp, and a new cabinet, to your Profiler's arsenal. You are now free to
combine each of them with other amps or cabinets to create new hybrid stacks.
You will notice that the GAIN knob is automatically set to the same (audible) position as the reference amp and
the amp volume is the same as the other amp volumes to make it easy to compare different amps. The actual
gain range of the Profiler is probably much larger than your original amp. This means that you can play the new
Profile from ultra-clean to super-distorted, even if you couldn't do so on the reference amp itself.
In situations where the reference amp was clean, the GAIN knob will be set to the minimum position, while retain-
ing all of the original volume. Of course, you'll have no trouble turning up the GAIN knob to distort this sound if
you want to! Inside the Profiler, the "Preamp definition" parameter has been set to the center position, and can be
modified at any time.
When it comes to crunch or high-gain sounds, the "Preamp definition" value is automatically set to a position
that matches the reference amp. You can thus identify the virtual age of the reference amp, and even modify it
on-the-fly.
