That is one way to do it, but itâs not the traditional way.
The traditional way (which is, frankly, rather clunky, but comes from an era before digital) is to plug your guitar into the amp, and then record it with a microphone into the recording equipment.
Many people still do this because you are capturing the sound of the amp, the speaker and speaker cabinet, the room acoustics, the microphone, and the pre-amps of the audio interface (AI).
The key thing is that ALL of these things have an important part to play in the sound of the electric guitar on a recording, and if you plug directly into the AI you will be missing most of those; the recording will be âdryâ and not sound right.
Also, what you have described is the wrong place in the chain for a looper, unless you are trying to do something particularly weird.
As @RobDickinson has pointed out, you can do it like this, but using modelling software on the PC, usually in the form of DAW plugins, to emulate the sound of the amp, speaker, cabinet, room, and mic.
In theory, if you output the dry recorded signal to the input of the amp (the guitar input, not the aux input) it will sound correct. But this is an unusual and, I suspect impractical approach and not what you need. I think you need to record the sound of the amp.
The normal recording chain is:
guitar->Distortion & FX->looper->amp->cabinet->microphone->AI->PC
In the case of a guitar amp with onboard FX, you really need to place the looper after the FX, which is why people are suggesting the Katana 100, as it allows you to do this. The Katana 50 doesnât really support this.
The AI and PC should be the last in the chain.
Note that many modern guitar amps have onboard audio interfaces and support modelling of guitar speakers, cabinets and microphones. The Katana is one of these. In other words, if you want to record guitar into a track, you donât need a separate audio interface; you can just plug the Katana USB into your PC directly. It will show up as an audio interface, and you can record from it using the built-in speaker cabinet and mic emulation. You can also record in stereo if you are using stereo effects.
If you want to multi-track many things at the same time as the guitar, this may not be the best approach as, in general, with DAWs you can normally only use one audio interface at a time (the reason is to avoid clicks and pops between AIs that are not synchronised). But if you are multi-tracking one thing at a time, it probably is the best approach (certainly the easiest)
Yes, it does, but only on the USB.
There are 2 stereo channels on the Katana USB: channels 1 & 2 have a wet stereo signal, channels 3 & 4 have a stereo dry signal. For playback, this is reversed.
One (annoying) thing about the Katana is that when you play back through USB channels 1 & 2 it does not go to the speaker, only to the headphones.
Having said that, for recording and mixing purposes, you probably want to be going through a separate AI with a good pair of monitor speakers anyway.
