Can you reproduce the sound of an Orange PPC412, a Fender Deluxe Reverb, a Marshall 1960A, a Mesa Rectifier, a Vox AC30, a Roland Micro Cube, an Orange Micro Crush...? Yes you can!

Orange PPC412     Fender Deluxe Reverb     Marshall 1960A     Mesa Rectifier 4x12     Vox AC-30    Roland Micro Cube    Orange Micro Crush


Orange PPC412

Fender Deluxe Reverb

Marshall 1960A

Mesa Rectifier

Vox AC30

Roland Micro Cube

Orange Micro Crush

For each sample:

* 1 rhythm guitar to the left
Amplifier simulator Aradaz Crunch
Cabinet simulator LeCab, with the following impulses:
1 cab 80% left (microphone Royer R-121), 1 cab 60% left (Shure SM57)

* 1 rhythm guitar on the right
Amplifier simulator Aradaz Crunch
Cabinet simulator LeCab, with the following impulses:
1 cab 80% right (Royer R-121), 1 cab 60% right (Shure SM57)

* 1 solo guitar in the middle
Amplifier simulator LePou LE456
Cabinet simulator LeCab, with the following impulses:
1 cab 10% left (Royer R-121), 1 cab 10% right (Shure SM57)

This configuration is always the same, only the cabinet changes
(Orange, Fender, Marshall, Mesa, Vox, Roland)
For Roland Micro Cube and Orange Micro Crush, I used impulses that I created, (downloadable here), with a combination of a Shure SM57 dynamic microphone and a Rode NT5 static microphone.

For all other samples, I used impulses from the Redwirez retail collection.

As you can hear, even when always using the same amp head, the final sound will change a lot depending on the cabinet and the mike used, which is completely logical. You must find the right combination between the head and the cabinet. You can even use the head only if you wish. All of this is virtual, you may do things the way you like them!

On the Internet, you can find impulses made by people and freely distributed. Unfortunately, their quality goes from excellent to very poor. The only way to know is to try them. I gathered some impulses from various cabinet brands: Mesa, Fender, Marshall, Vox, Orange, Soldano, London City... That's already a very good start. The microphones used to make these impulses are classics from Sennheiser, Shure, Rode, AKG, Neumann...
For free, you will have something to make some good mixing.

I add two zip files containing a total of about 950 more impulses. It's a wide collection, but the file naming is somewhat messy. Some names are crystal clear, some others... you'll have to guess...

On this page, you can download impulses that I created with my own amps. Audio samples will give you an idea of the type of sounds you can expect.
These impulses are audio files to use in impulse loaders such as LeCab 2 or MixIR 2, in order to assemble a virtual cabinet simulator.

You can download free impulse loaders from this page.

You can also buy professional, high-quality impulse packages. They sound really good, because the designers of these impulses have access to a lot of hardware and can provide us with a wide range of impulses. With each cabinet, several microphones are used, and each microphone is placed at different places before (or even behind) the cabinets, so you get nuances that will enrich the sound. Users can then combine several impulses for each guitar or bass take in order to get THE sound they're looking for.

REDWIREZ (web site)

This company offers the best cabinet impulses I ever tried. In the "Big Box Series" collection, Redwire offers 31 cabinets (some in several versions):

    - "Modern Classics" series: Bogner 2x12, Bogner Uberkab, ENGL Pro 4x12, Halfback (Bottom, Top Closed, Top Open), Krank Krankenstein, Krank Revolution, Marshall 1960, Matchless ES212, Mesa Rectifier 4x12, Orange PPC412, Peavey 5150 4x12, Roland JC-120, Soldano 412B

    - "Vintage Classics" series: '68 Marshall Basketweave, '75 Hiwatt SE4123, Fender Deluxe Reverb, Fender Dual Showman, Fender Twin, Marshall 1960 4x12, Mesa Mark II, Supro Thunderbolt S6420, Tweed Bassman, Tweed Deluxe, Vox AC30

    - For bass guitars: Ampeg B15, Ampeg SVT 810, Aquilar DB115, Hartke 4.5XL

They also offer impulses coming not from cabinets but from specific speakers placed in generic boxes:

    - Celestion Blue 12, Celestion G12H30 12, EVM12L 200w 12, Weber Blue 12

Microphones for guitar amplifiers: AKG C414B-ULS, Audix i5, Beyerdynamic M160, Coles 4038, Neumann U47, Neumann KM84, Neumann M8/CMV563, Neumann M7/CMV563, Neumann U87, Royer R121, Sennheiser MD421N, Sennheiser MD441, Sennheiser MD409, Shure SM7, Shure SM57, TAB-Funkenwerk SM57, Electrovoice RE20, Earthworks TC30/M50, Lawson L47, Blue Bottle/B4 (Room only), Blue Bottle/M7

Microphones for bass amplifiers: AKG D12, AKG D112, Audix D6, Beyerdynamic M380N, Coles 4038, Earthworks TC30, Electrovoice RE20, Heil PR40, Neumann U47FET, Royer R121, Sennheiser e602, Sennheiser MD421, Shure Beta52, Shure SM7, Shure SM57

Each cabinet offers a minimum of 550 impulses. The whole collection costs 121 dollars (about 90 euros), which is OK considering the number of impulses and the amount of work put into it. And good idea: you can buy each cabinet impulse collection separately. You get the first cabinet collection for 10 dollars (about 7 euros) and the next cabinets will grant you volume discounts.

RECABINET (web site)

I bought their Recabinet 2 collection which contains the following cab impulses:

    - "Modern 1" Series : Line 6 Vetta 4×12, Marshall 1936 2×12, Genz Benz G-Flex ported 2×12, Mesa Standard Oversize 4×12, Krank Krankenstein 4×12, Carvin 4×12 British Series, Ampeg SVT 8×10 Bass Cabinet (for bass), Marshall Hand Wired 4×12, Roland Micro Cube

    - "Modern 2 Series" : Marshall 1960AV 4x12, Randall RS4 12XLT 100 4x12, Mesa Engineering Standard 4x12, Orange PPC412-C

    - "Vintage" Series : Fender 1965 Super Reverb 4x10, 1970s Marshall 4x12 with Celestion Greenback Speakers, 1960s Ampeg Portaflex B15N (for bass), Vox AC30, 1953 Fender Deluxe 1x12, Selmer Zodiac Twin 30

Microphones used: Shure SM57, Shure Unidyne III 545, Royer 121, Sennheiser MD409, Sennheiser MD421, Audix i5, Audix D6, Neumann U87, DBX RTA, Audio Technica 4060

In total, there are 1959 impulses. A large choice that is difficult to sort out at first, but I gradually spotted combinations of impulses I find quite satisfying to my taste. I chose this collection because user reviews were enthusiastic and it is very affordable: 15 dollars for the whole collection. At this price, I did not hesitate for long: spend 15 dollars for quality impulses or spend hours to find good, free impulses without any guarantee to find something useful, it was an easy choice...

Since then, they released Recabinet 3 (winter sales at 20 dollars in January 2013). New impulses and a new, more convenient interface. I said I wouldn't buy it but finally gave it a try thanks to a discount price... and I'm a bit disappointed. Recabinet 3 is not bad at all, the interface is pretty nice and it works smoothly. But I find the interface not as complete as the free Poulin's LeCab2, and more importantly, the impulses are integrated within the interface, so they cannot be used separately with an alternate impulse loader, and also I still prefer thesound of the Redwirez impulses. I think they are better defined, clearer and more accurate. So I would recommend Redwirez, but that's a very personal choice! Nevertheless, Recabinet 3 is a good product... but it isn't the best.

I have compared the sound of a few impulses from the 3 commercial impulse libraries that I own. Of course, I chose impulses that are as close to one another as possible.

For the left rhythm guitar, I used two impulses taken from a Vox AC30 2x12 cabinet: one impulse from the microphone Royer 121, position Cap Edge, about 10 cm (4 inches) from the speaker, and one impulse from the microphone Shure SM57, position Cap Grill (centered, against the cab grill).

For the right rhythm guitar, I used two impulses taken from a Fender Deluxe (Deluxe Reverb for Redwire, Deluxe 1953 for Recabinet 2 et 3) 1x12 cabinet: one impulse from the microphone Royer 121, position Cap Edge, about 10 cm (4 inches) from the speaker, and one impulse from the microphone Sennheiser MD421, position Cap Grill (centered, against the cab grill).

For the centered solo guitar, I used two impulses taken from a 4x12 Orange cabinet: one impulse from the microphone Royer 121, position Cap Edge, about 10 cm (4 inches) from the speaker, and one impulse from the microphone Neumann U87, position Cap Grill (centered, against the cab grill).

The obtained sound is rather different from one impulse library to the other, although it was made with similar cabinets and the same microphones. This shows how difficult it is to make perfectly reliable impulses, and it also shows how the recording conditions will affect the result. I can't tell which library sounds the most realistic, as it will be a matter of personal preference. And you can always EQ the sounds to make them sound the way you want.

Bravo Xavier, juste un petit mot de soutien, je suis impressionné par ton site et tes compos, très motivant pour un "jeune" débutant comme moi, je ne manquerais pas de revenir pour en écouter plus et profiter de ton expérience.
Bonne continuation et merci.

Merci à toi, ça fait plaisir !

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.
