Hi everyone,

there has been a lot of talk lately about tone matching, which basically means that you capture the EQ curve of a reference signal lets say your favourite guitar tone. Then you capture your own tone. The resulting differential EQ curve then can be applied to your own signal to create a very similar tone.

Most KPA users get great tones by capturing their amps but many users never got in touch with recording, mixing or producing. This is why many users are not sure how to EQ their guitar tones in order to make them work nicely in a mix.

I never really got into all those "eq matching" plugins so i thought i might be a nice opportunity to experiment a little bit since i wanted to test profiling through a DAW with VST plugins applied to the profiling signal. So the setup was as this: GUITAR -> KPA -> AMP -> CAB -> MIC -> DAW -> PLUGINS -> KPA Return. I used Izotope Ozone as EQ matching plugin which worked pretty nicely.

First step is to choose a reference (guitar only) soundclip that you like and to capture the EQ curve with ozone. The resulting EQ curve will be the "target". Then record the same riff or lick with your KPA profiling setup to make it comparable and also capture this. The resulting EQ curve will be the "source" that will be tranformed.

Then you need to set your own tone as "source" and the reference tone as "target". Now you can simply transform your tone into the target.

My goal then was to apply this EQ curve to my profiling signal, while activating the real time monitoring which depends on the latency of the audio interface. The KPA seems to tolerate and compensate latency so this should not pose any problem. In my test the resulting profile came pretty close to the reference file. Don´t await a 100% match but it might be of use as a guideline for finding the right frquency balance for your guitar tones...

Take care...

Edit:

Thx to HappyKemper, he send me this nice tutorial how to use eq matching with ozone.

Just tried to match a few classic metal tones. I used the same basic amp and mike setting for all tones, JVM + V30 + SM57. If you would tweak a little more or start with a closer basic tone the results might even get better. However it is pretty amazing what difference EQ settings do make on the same tone.

Made a quick n dirty comparision clip for you. Originals are first.

Why not... keep in mind they will sound different with other guitars...

Here is a new version, a little bit tweaked:

I think i might ne nice to create some "artist profile packs"...

Quoted from "and44"

nice idea.
however, sorry to be a stuck in the mud, but the problem with artist profiles, is it really depends on your setup.. - you could make i.e a "Money for nothing" sound perfect, but the chance of that happining on another persons rig, with a different sound, moniters etc.. is very slim.

This is true to some point. But the good news is that you easily can get the remaining few percents by just combining rigs with the corresponding eq curve in the DAW. This is very corfortable in ozone, since you can store and name as many curves as you want and import them on other DAWs. So if your recording doesnt fit 100%, just match it with the original and the result is nearly perfect. I am really beginning to love this software.
