This is an essential step. As we are doing Rock music, we are necessarily going to use guitars. And it'd better sound good and heavy and impressive. If guitare comes second, it's not Rock anymore, so you must take very good care of it. But in a home studio, it is not easy to have access to good hardware that will take our guitar sounds to the next level. Real guitar amps are expensive, take space and are very noisy but fortunately, virtual amps have made enormous progress and anyone can now get gear simulations of all kinds.

Amp simulators attempt to reproduce the sound of real guitar and bass amps. Some will recreate one precise model, some will offer access to different models and brands. You can easily find reproductions of the most famous brands from one simulator to the next, but their quality and fidelity to the original can vary much from one sim to the other. You can find both free and retail simulators.

Amp sims of course are only necessary if you don't use a real guitar amp. A good amp sim will allow you to play and record with very limited noise and give excellent results. Frankly, it becomes very difficult to distinguish between a good amp sim and a real amp. Simulators have a bit less dynamics, grain and warmth, but within a good mix, the difference is subtle and if you set the right parameters, most people won't hear any difference. Another advantage in favor of simulators: it doesn't take any physical space and you can have many different models at your disposal without spending a fortune. On the other hand, when it comes to live play, nothing is worth a good old guitar amplifier... But here, we're talking about recording in a home studio.

Caution: I put forward amplifier head simulators, to which you need to add speaker cabinet simulators to build up a complete guitar amplifier. As you can hear, it sounds rather aggressive without a cabinet. According to the cabinet, the microphone and its positionning, you can get very different sounds. It's up to you to find the desired setting. Don't hesitate to use several cabs and several mikes for a single guitar as it allows for a fuller sound.

NB: all the plugins presented here are for PC with Windows. If a Mac version exists, I'll mention it and give you the download link from the official website.

Guitar => Audio interface => D.A.W., in which you have an amp head simulator (here: Poulin LE456), followed by an impulse loader (here: Poulin LeCab 2) in which you load an impulse that simulates the desired cabinet.

How to use these plugins:

As each D.A.W. is different, I cannot give you the exact procedure but only a general method. Caution: as a Windows PC user, the files I present are for Windows, and so are the explanations below.

     1 - Download the plugin file you are interested in.

     2 - Unzip the plugin and copy the files it contains in the VST folder of your D.A.W.. I advise you to create a folder for each plugin.
For instance, if you download the TSE X50 zip file, copy its content within the folder "C:\...\VST\TSE - X50".
In order to sort things better, I usually create this type of sub-folders "C:\...\VST\Amp simulators\TSE Plugins\X50", so everything is sorted by type of plugins and by brand.

     3 - If your D.A.W. doesn't automatically do it when starting, use its plugin search/analyse function. You may have to close and restart your D.A.W. to recognize the newly installed plugins. Check in the D.A.W.'s options that it knows where to look for. It is usually possible to set one or several paths that will target the folder(s) containing your plugins.

     4 - Once the new plugin is recognized by your D.A.W., place it on the track or the bus you want. Some plugins only work if they are placed on stereo tracks or buses.

     5 - Place an amplifier simulator first.

     6 - Then, place a cabinet simulator, also known as an impulse loader, like LeCab 2 from Poulin, or NadIR, for example.

     7 - In the cab simulator, load the impulse of your choice. Impulses, whether they are free or commercial ones, are small-sized wav audio files that you will place wherever you want on your hard drive. They don't need to be located in your VST folder. So load the impulse of your choice, for example a Marshall cabinet impulse.

     8 - If everything goes well, you now have an amplifier simulator and a cabinet simulator, very much like a real amplifier.

     9 - Click on the "monitoring" button of your guitar track, the very one that allows you to hear yourself playing. You can now enjoy the sound of your virtual guitar/bass amplifier.

     10 - Change the settings in the amp simulator windows, set the volume, the bass, mid and trebble, etc. Change the settings as well in the cab simulator if needed (high and low pass, panning...)

     11 - Pay attention to the latency. Set it low enough so that there is no delay between the moment you play your guitar and the moment you hear the sound coming out of your headset or monitors. Latency only needs to be very low when you play or record (in order to avoid a sound delay). Once the recording is over, when it is time for mixing, you can raise the latency again, in order to get more processing power. The lower the latency, the more the computer processor will be in use. That can be problematic with big musical projects, if your computer is not powerful enough to process things in real time.

Je viens de prendre connaissance de ton site, c'est pas mal du tout, je voulais me mettre aux IR depuis un bout de temps, et là j'aurais quelques questions.

J'ai énormément de matériel de musique et j'aimerais tout centraliser dans un Helix.
Pour ça il faudrait que je puisse séparer chaque élément de mon rack et de mes pédales de manière indépendante, est-ce possible?
J'imagine que oui, il suffit simplement d'avoir une différence entre l'entrée et la sortie des appareils, comme les tutos que tu proposes.

Par contre j'aimerais pouvoir faire une IR de mon ampli de puissance et là je bloque un peu.
En effet, si je veux sortir le son de mon ampli de puissance il faut obligatoirement que je passe par un baffle et là ça va colorer mon son. Existe-t-il un moyen de récupérer juste un fichier IR de mon ampli de puissance un Mesa Boogie fifty-fifty.
Et pouvoir aussi récupérer un IR de mon baffle seul.

En fait ce que vous je voudrais faire dans le Helix c'est pouvoir charger plusieurs IR de chaque élément de mon rack, un pour le preamp, un pour l'ampli de puissance, un pour le baffle...

Si tu as des idées pour faire quelque chose, je serais ravi d'avoir tes conseils, merci d'avance

Félicitations pour ton site. J'essaie de télécharger les simulateurs d'amplis gratuits sans succès. Je m'y prends certainement mal car je débute. Mon matériel : PC I5 64 bits. DAW Reason 9.5. J'ai créé un dossier VST ajouté dans préférences ... Avancé. J'y ai transféré le fichier DLL mais impossible de l'ouvrir sous Reason. Merci par avance

Solid work across the board. Found myself here because of your amp heads and then never left!

Glad you find the place nice and cosy. You're welcome here!

Merci pour ce tuto !
Le seul bémol que j'apporterais, c'est la dynamique finale : ne pas céder au chantage mais rester à -14 / -12dB RMS si on exporte sur CD. En revanche, -12 / -11 dB pour un mp3 192kbps paraît acceptable.

* * * * * * * * * * * * * * * *

Oui, dans la mesure du possible, je confirme que c'est bien de rester à des niveaux inférieurs à -12dB. Il faut tendre vers ça le plus possible. Mais en arrivant à -10dB dans mon exemple, je fais malgré tout déjà mieux que la plupart des albums actuels.
Quant à l'export CD, il est quand même de plus en plus rare. La plupart des gens écoutent désormais leur musique depuis leur téléphone portable, et bien souvent en mp3. Et honnêtement, la différence entre un fichier wav et un fichier mp3 à 320 kbps est indiscernable pour 99 % des gens. Même à 192 kbps, rares sont ceux qui sont capables d'entendre la différence, surtout quand c'est écouté au travers d'écouteurs ou d'enceintes bas de gamme ou moyenne gamme.

Bonjour et merci pour votre site sur la MAO que je ne connaissais pas il y a encore quelques mois.
Je suis sur PC Windows 10 système 64 bits, séquenceur Reaper. J'aurais voulu savoir comment récupérer les réglages des presets (.fxp). J'ai téléchargé le preset exemple pour les amplis LePou, je l'ai enregistré dans mon répertoire VST, et là je ne sais pas comment récupérer le réglage. Autre petite question, dans le preset, y a-t'il la définition et le réglage des impulsions ? Merci d'avance et encore merci pour toute l'aide que fournit votre site.
