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 Cabs, mics and speakers.

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, 32 bits floating point WAV files. Their length is usually 50 ms, though some files may be shorter. You will probably need to adjust their phase if you want to mix them with IRs from other vendor/provider.

Two amps are used for OverDriven.fr IR creation : one using KT88 valves, the second one using 6L6 valves (this is generally mentioned in the directory name of the IR files or in the readme file of the collection).

These IR are systematically tested under Two-Notes WOS running in Logic Pro X, and they are sometimes tested under Nadir (still under Logic Pro X), the Two-Note CAB M. pedal and the Mooer Radar pedal.

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 CAB, mic or speaker to the other. Sometimes, EQ’d versions of the IR can be provided in subdirectories. In this case, read the readme file to get information about the EQ.

Some advices

  • These 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)
  • Pay attention to P00, P05, P09 positions , especially at high volume, as they can be harsh (lot of treble).
  • You may need to slightly boost the 100H to 500/700 HZ frequency range in order to get more presence and bass.
  • I suggest to use low-cut filter (50HZ-120HZ) and high-cut filter (7500 HZ or less) to achieve better results.
  • 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.

File naming convention

IR are provided as collections : a collection represent 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”.
  • -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).
