muted every time you switched back to the PROFILER/profile, a valid A/B comparison would be impos-
sible.
When you are satisfied with the A/B comparison, you may wish to evaluate the pure profile; in this case, it
would make sense to mute your reference amp. Press the ON/OFF button to mute the reference amp; any
other action will unmute it again.
Refining the profile
After the automatic profiling procedure, the profile is nearly done and very close to the original already.
Now it's time to give it the final polish: press "Refine Profile" and play your guitar for about 20 seconds.
This is no time for a meaningful solo - you need to play several chords, with attitude! This will generate
inter-modulation in the distortion that the PROFILER needs to do its refining. Be sure to strum especially
hard so that the PROFILER has a chance to analyze the transients. When you feel that you have refined the
profile enough, press the blinking soft button to stop the process. Now make another A/B comparison to
check the result. Repeat the process if necessary as many times as needed.
The Refining process is actually independent of the type of your guitar. It is about adapting the distortion
characteristics, as well as polishing the attack and dynamic response. The resulting profile will act and re-
spond accurately no matter what guitar or pickup you use.
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 vol-
ume in the transients 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" op-
tion.
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 pro-
duces more high frequency 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.
