Impulse Responses For Guitars

  • I've been working a lot with the IR loader for the convolution reverb and it got me thinking...

    Would there be a way to make an IR loader so we can use guitar tone impulses? I'd love to make a guitar plugin!

  • @SteveRiggs how would you generate these IR files? - or is that what you are asking?

  • @SteveRiggs said in Impulse Responses For Guitars:

    You can use the Convolution reverb to load Cabinet Impulses right now. I've been using Deconvolver to make my Impulses.
    Guitar Tone, on the other hand, can't be captured with an impulse. It can only be space and frequency response.
    You'll need to create the functions of a guitar head separately (most likely do-able in ScriptNode, when it's ready) and feed that into your Cabinet impulse.

  • Yeah of course you can make a guitar cabinet model with the Convolution module in Hise.

    Like @dustbro said, I am also using Deconvolver for this. This is a good tutorial for making your own guitar impulse responses 😉

  • @orange - er isnt that an IR of a guitar thru an amp - not a guitar?

  • @Lindon @dustbro @orange

    Cheers for the replies fellas. I'll take a look at this properly then. I'm using the Fortin Nameless Suite and STL Tonality at the moment as my rig since I sold my Marshall (still kicking myself!) but still have access to a bunch of other nice cab/amp setups I'd love to make IR's from. If I can make a decent sounding head emulation to run through it this looks like it could be a winner down the road. I'll probably take a bit of time over this to get it right! Let the experimenting commence! 😎

  • @SteveRiggs Theses days I stick to a Boss GP-10 in the real world -ts not quite my Rick360 thru my Vox AC-30 but its close, and its got all those other guitars and amps in there too...

  • @Lindon

    Badass. The GP-10 looks cool. Not tried it myself but I used to have the GT-10 a few years back. I ended up selling it to get a Korg AX3000G instead. It wasn't the best swap to be honest! I only use it for the wah pedal and pitch shifter now and run that into the Nameless or STL. It gets the job done ☺

  • @Lindon

    • He picks a guitar tone from a song.
    • Then plays the same riff (in order to catch the similar frequency spectrum).
    • Then applies some guitar amp to the DI track.
    • After applying amp, he makes an EQ match process to emulate the cabinet sound of the song.
    • Then process the Deconvolver's sweep tone through the Matched EQ tone.
    • It's time for Deconvolver, process it, and Done 🙂

  • @SteveRiggs Fortin Nameless Suite is one of the best tones in the market, for my ears. Really great plugin.

  • @orange wow how complex - and sorta not likely to be too accurate...

  • @Lindon Actually it's incredibly accurate, this is almost identical to how I made my brass mute emulations for Sordina 😉

  • @SteveRiggs yeah I was a VG-8 and VG-88 user before it - but they got lost/toured/giged to death/stolen/"roadied" the GP-10 sits quietly in my studio mostly not doing much....I did promise my self I'd use it in some library at some point ... but the point hasnt shown up yet.

  • @d-healey wow OK I stand corrected...I'll have to pay attention to the video and see how I might capture the "tone" of some GP-10 guitars...<-- looks like that point might show up...

  • OK so I watched the video - hes a funny guy...BUT. its what i said - its a guitar + amp+fx tone - its not a guitar tone.

    I cant see how I'd use his technique(or Daves) to get the tone of a guitar , e.g. I have a Rick360 and a vox AC-30.... I want to get the "tone" of the Rick360 bridge pickup.....and NOT any part of the Vox AC30

    So basically I can put a signal thru the captured "Rick360" IR and then thru a "Marshall stack" IR and get a Rick 360 thru a Marshal stack... I cant see how this is possible _ I can do it for the marshal - just send the sine tone thru the amp and record that, but the guitar itself? cant see how - I'm probably being dumb.

  • @Lindon Yeah I don't think this technique would work either to get the tone of the instrument. I have seen people who hit instruments on the bridge to generate an impulse that can be deconvolved - I think the one I saw was to get a violin body IR but I can't remember now.

  • @Lindon Yeah it might not be accurate but it can be very close.

    The result IR tone depends on which amp you've used. Also the dynamic range of your amp will determine the frequency responses on different input volumes. Also while exporting Deconvolver sweep tone, you must bypass amp, because you want only cabinet sound, not the amp.

    Actually convolution technology is quite old for realistic guitar sounds. For a better solution, the new trend is "Amp Profiling". Check this out 🙂

  • @Lindon
    take a look at Peavey's Revalver 4, they tried to do that. you can choose a humbucker, a single coil pickup or even a guitar model to run your clean guitar through. it emulates the character of the chosen pickup pretty close, but I think it's just a EQ match. you know for sure, humbuckers sound fuller than single coils and so on.

    However, the pickup emulation is never completely accurate because its hard to emulate the circuit with coils and stuff. so you have to EQ match it. that's the only solution I have in mind.

  • yes thanks everyone -so not ever getting anywhere near a guitar IR, only really possible with serious modelling - @clumsybear @orange - yeah I took a look previously but those are pretty marginal solutions when you have one of these sitting in your studio:

    so what I was really looking for was a way to capture the tones of guitarrs without amps - but I can always pass a swept tone thru this and get guitar + amp

    In fact with it I can say guitar body shape, pick up type, and pickup physical position (even silly places like half way up teh (virtual) neck.

  • @Lindon cool 🙂

    btw - Kemper is state of the art amp modelling atm. great tool. haven't tried the gp-10 but I'll take a look at it
