Kemper Amps Forum

Hi everyone,

i just posted some signature metal profiles on the rig exchange. These were profiled with the help of the very powerful eq matching function of izotope ozone.

Here´s a comparison clip with the originals first and the profiles second:

The amazing aspect of this is, that for every tone i created, i used the same amp and mike settings. Only the ozone match eq is changed. As long as gain structure nearly fits, you can get decent results.

The technique of eq matching is basically the same that is used by the new tone matching function of the Axe-FX. By using a DAW with a plugin like ozone you can do the same for your KPA. It´s easy, fun and very powerful. It also has some educational aspect, as many users who are no mixing engineers or producers are not sure how to eq their guitar tones to produce a sound that will work nicely in a mix. The truth is that many guitar tones that sound great in a mix are not very pleasing if you play them solo. So getting into signature tones might give you an idea how to come close to a sound that will fit nicely into a song.

What is done here is very simple. Select an original guitar recording you like, where only the guitar is heard. You can use intro parts, or stems from guitar hero/rockband or other multitrack collections. Load that clip in your DAW. Then use your amp profiling setup and record the same clip as you good as as you can. Then match your recording against the original and apply the resulting eq curve to your own recording. Your recording should now be almost perfectly close to the original. With the EQ setting that´s enabled on your own recording you now can take profiles. That will give you a profile that´s pretty close.

The following video will demontrate how to use ozone:

The only difference will be that you do not create an IR at the end but take a profile.

The resulting profiles will need a little bit of tweaking to make them even closer. The results will be close enough to give you an idea of how the sound will be when recorded. However, if you record the same part again with the profile, the results might not reach a 100% match. What is really cool is that you can now simply use the tone matching on your recording again, and the results be a total match.

A great feature of ozone is that you can load and save to captured EQ curves so you could use my tonmatch sets in your own DAW to test out for yourself.

Here are tonematch sets i´ve done so far:

This is excellent stuff, thanks, Tills.

However I have one wish, I wish you'd do this with some tones besides Metal..because I don't play no metal.
This would be amazing if it could be used to capture some classic/hard rock or bluesy tones...or some of the tones on the GregV Youtube amp demos.

Basically this would be possible if you just send me a short reference guitar only clip and your own dry DI recorded version of the same clip. At least worth a dry. But makes only sense with at least crunch tones. Clean tones will vary too much on the used pickups.

Hi Tills,

It looks interesting

Can you tell me how you take the profile?

thanks

Basically it is just the same as if you were profiling normally. The only difference is that you have the DAW with the ozone plugin between your amp mic and the KPA return.

Instead of connecting the mic to the KPA return you put the mic into an input of your audio interface. Inside your DAW you have an audio track with the matched eq curve active. You then just need to activate the real time monitoring for that track to hear your profiling signal with the eq match plugin enabled. Then just take the profile as normal. Don´t worry about the additional latency of your Audio interface, the KPA will compensate for that.

YOu can also use this method to capture your amp in combination with some nice IRs like redwirez, if you use an IR loader insteaad of ozone. Endless possibilities here...
