Same problems for guitars and bassâ€¦ same solutions ;-)
You have 3 solutions :
Record with a mic
If you want to record the real sound of your amp, you must plac a mic and record it with your sound card. This is the more â€œclassicâ€ way to record a bass or a guitar.
you will record exactly the sound you are used to ear when you play.
you need to record in a quiet room to avoid perturbations,
Most of the time, you must play loud to get the sound you want from your ampâ€¦ I would not advise if your home studio is in an apartment ;-)
You will ear the result after you have record. Youâ€™ll often have surprise like saturation, equalisation, problem of dynamic, vibration of metallic part of the amp (yes it happens!!!!), etcâ€¦
Use a modelling preamp/amp
You can use modelling preamp like POD, V-AMP, J-Station, etcâ€¦ Even Fender has launched a modelling amp some months ago.
you record what you ear
really little noise compared to a mic
you have different amp models in the same box
you can play and record with headphones: your neighbours will thank you!
And the acoustic of the room doesnâ€™t matter!
You will not find exactly the sound of your amp...
Use modelling software
This is the same concept than modelling preamp. But your guitar is directly plugged in you sound card, or in your preamp. You have different possibilities for that: line6 launched a TDM plugins â€œAmp Farmâ€ some years ago, Steinberg has the â€œWrapâ€, Cakewalk has the â€œFXâ€, and IK Multimedia has Amplitube. I personally prefer Amplitube.
The main advantage
compared to a modelling preamp is that you record a â€œcleanâ€ track with your guitar, and you process the sound after recording. So you can choose to change the amp, the equalisation, the drive when you are mixing, and you donâ€™t need to make a track again to change the colour of your sound!!!
I use a Pod XT
that is between a software and a modelling because it can be plugged via USB on your computer, and is recognise as a sound card. This is my preferred solution for bass and for guitar.
