Free Guitar Cabinet Impulse Responses

The guitar cabinet impulse responses available on this page are created by me, in home-studio conditions. Before proceeding with download, please consult the terms of use, and more specifically the “impulse response” section : https://overdriven.fr/overdriven/index.php/fr/about/.

These impulse response files (IRs) are free and as mentioned in the Terms of Use, no warranty of any kind is provided with these files (issues, sound problems, inability to use them, sound quality, damages of any kind…).

They can allow you to get started with IRs and to experiment and/or enrich your IR collection and your sound palette. They might also allow you to discover new guitar cabs, speakers and microphones.

Buy me a coffee

You can support my website and the IR publication work by making donations through Buy me a Coffee :

Buy me a coffee is simple and easy : you can do a one-time donation very simply …. so, if you want to provide me some support for the free collections and help me providing new collections with new cabs/speakers/microphones to the guitar players community, that’s the way to do it !

Basic IRs collections will remain free for all users of the website : they contain a basic set of microphones. Additional content will be made available through a Buy Me a Coffee fee : these will consist in additional microphones and IRs mixes. This additional content will be accessible by using the download code provided when buying a Buy me a Coffee “extra” : you can check these collections on this page https://overdriven.fr/overdriven/index.php/sponsored-impulse-responses/

Check the next section for technical information on IRs : they are compatible with many IR loading software and hardware devices including Nadir, Two-Notes hardware, Two-Notes Wall of Sound, Libra, Helix devices, the Kemper Profiling Amp, Mooer GE multi-effects, Mooer Preamp X2, Mooer Radar, Engl Cab Loader, Hotone multi-effects, TC Electronic Impulse,… Before buying a Buy me a Coffee overdriven.fr extra, download and test the free collections to make sure your device or software work with them.

IR capture and technical information

These IRs are created with Apple Impulse Response utility, in 24 bits / 88,2 kHz and are made available as 44,1 kHz, 24 bits WAV files. Until Gen 4 (see below), IR length was usually 50 ms (though some early collections may be shorter). As of Gen 4, IR length is set to 100 ms. IRs are provided in MPT format : you will probably need to adjust their phase if you want to mix them with IRs from other vendor/provider in non-MPT format.

Three amps are used for overdriven.fr IRs capture : one using KT88 valves, another one using 6L6 valves and a third CLASS-D one : this is generally mentioned in the collection name of the IR files and in the readme file of the collection.

These IRs are systematically tested under Nadir running in Logic Pro X, and they are sometimes tested under Two-Notes WOS (still under Logic Pro X), Libra, the Two-Note CAB M. pedal and the Mooer Radar pedal and Overloud SuperCabinet. They will also work well on Hotone Ampero and Mooer GE multi-effects, the Kemper Profiler, Line 6 Helix or Tonex plugin and the Tonex pedal, the TC Impulse Loader, the Engl CabLoader for example.

In case of issue -unability to load them- please leave a comment on this page with the complete file name of the IR and the software or hardware you are having issue with.

All mics positions are not available and all positions that I record are not made available in the free collections. Distances and positions may be different from one cabinet, microphone or speaker to the other. Sometimes processed versions of the IR can be provided. In this case, read the readme file and the IR information page to get information about the EQ or filters applied.

Getting started with IRs ?

To get started with IRs and learn more about using them, I suggest reading the following blog posts :

Some advices

The CLASS-D IRs are captured with neutral settings, for minimum coloration and “flat” tone.

For the 6L6 and KT88 IRs, please consider the following recommendations:

  • The KT88/6L6 IRs are for the most part already medium scooped : I suggest you do not overly scoop your amp or preamp EQ. You can get started with a high level of medium (11H or 12H) and high level of bass (11H or 12H)
  • You may need to slightly boost the 100H to 500/700 HZ frequency range in order to get more presence and bass.
  • These IRs may need an output volume boost in order to sound as loud as OwnHammer or Two-Notes average IRs (from +0,5 DB to +2 DB for example). Please remind that EQ settings might impact the overall volume of the IR as well.

And more generally :

  • Pay attention to P00, P05, P09 positions , especially at high volume, as they can be harsh (with a high level of treble).
  • I suggest to use low-cut filter (50HZ-120HZ) and high-cut filter (7500 HZ or less) to achieve better results.

For Two-Notes systems :

  • On WOS / CABM / CABM+ / CaptorX, select 40 ms and original (up to Gen 3 ), 40 ms or 100 ms original in Gen 4

File naming convention

IR are provided as collections : a collection represents a recording session, with a given amp, CAB, speaker and mics.

The file names of the IR look like the following :

/overdriven.fr/6L6-SerieII/Fatboy-G12K100/OD-FB-G12K100-E906-P10-25.wav

The recording position uses a number with the following convention:

Mic positions

File names are made of the following parts :

OD-FB-G12K100-E906-P10-25.wav : OD_<CAB>_<HP>_<MICRO>_<POSITION>_<DISTANCE>

  • OD is the prefix for our IRs (OverDriven.fr)
  • FB : codified CAB name, in this case a Zilla® Fatboy
  • G12K100 is the speaker name : a Celestion® G12K100
  • E906 : a Sennheiser® E906 mic
  • P10 : mic position 10 (Cap Edge)
  • 25 : mic at a distance of 25 mm (distances are approximate), i.e. 1 inch.
  • File names may sometimes contain other information such as “HPF” or “v2”, or settings used in a specific capture session, such as :
    • -M0 to -M7 indicates some EQ was applied to reduce the medium scoop
    • -BRIGHT is a preamp effect applied to boost mids and high frequencies. It provides a lot of clarity for attack and definition
    • -SAT and -SAT2 are additional distortion settings from the preamp that brings also clarity to the IR
  • PxxA indicates an angled position (for example P10A would be P10 with a 45° shift)

Collections will contain the microphone preamp name : TubePreamp1, TubePreamp2 or SSP1 (Solid State Preamp 1).
