Hi everybody! I urgently need an impulse response of an e-guitar body (Strat, Les Paul, etc...). Does anybody know where to get this?

I don't think these exist. If you can describe how to produce these, and what you're going to do with it, I'm sure some people here might be of assistance...

yeah Im not really sure how this would be produced, but enlighten me and I will produce some of my epi sheraton, fender strat, and mandobird.

Thank you for your responses!

Just send a impulse to your guitar body and recording it...

In fact: knock on the wood and record this sound

This is not the best way but it works for what i need this.

Record with a mic, or with the elements? And could you please explain what you're going to do with it?

I want to use it in Kontakt in a guitar instrument. To get more body resonance.

I don't know how to record it the best way. I think a good mic should do the work.

I always thought e-guitars didn't have body resonance (except for those hollow-bodied ones)? Solid wood doesn't really resonate, you know. And if it did, it wouldn't be picked up by the pickups.

Marc, I am guessing guitar is not your first instrument? Of course the body resonates - why do you think people use expensive timber in electric guitars and then paint solid colours over it? Timber in guitars isn't just there for cosmetic purposes.

If there were no resonances MDF or plastic would do fine for guitar bodies and there would be no difference in sound between a maple and rosewood finger boards on Fender Strats and Teles and Jazz Basses. (In fact plastic electric guitars and MDF ones have been built they just don't sound the same as mahogony or ash.)

The resonances affect the guitar tone even when you are plugged into an amp simulator.

The body and the strings interact and the change in the frequency spectrum is transimitted by the p/us.

It is indeed not my first instrument (nor my second, tbh...

). Still, I have a hard time believing that a solid piece of timber could resonate that much and have an audible influence on the actual sound. Still, happy to take your word for it.

You could do it the same way you test a piece of wood to hear if it has good sound response.
Hold a piece of wood, by the top, between 2 finger tips and knock on it, bellow in the middle, with the tip of a finger (of your other hand , of course) on it.

I wouldn't do it with a guitar, but with the guitar body only. Easier : just a solid piece of wood.

The quality of the wood for a solid body guitar is VERY important.
If you wanna buy a solid body guitar you also have to play it without amp connected.

This is luthier info.

Cheers, knock on wood,

Max... .. .

Hi Dynamitec,
I think I know what you want.
I figured out something that works really nice,
Its a bit more complex than just knocking on wood.
And in my opinion the kind of wood does not matter.
The kind of strings and pickups you use is more important,
since its not the wood that sounds but the strings.
There are great sounding E-Guitars without any wood.

On Acoustic-Guitars the wood is much more important than on E-Guitars.

Unfortunatly I'm not allowed to tell you how I captured and programmed
the body-resonance bevore my Guitar-Library is released.
But this will be very soon.
Sorry for that, but if I forget to tell you after the release, ask me again.

Your script-work and the guitar.cocept look great.
I wish you much success with your guitar.

Chris Hein

Chris Hein, with all respect, if in your opinion the kind of wood (of a solid body guitar) doesn't matter, then in my opinion, based on 35 years of experience, you know very few things about a solid body guitar !!!

I can even tune a solid body so that it gets more sensitive and gives more sustain at a defined frequency !!!

Warm greetings,

Max el Luthier... .. .

trying to go back on topic..(rare from me, huh?)

I remember that something to capture el.guitars irs was announced by the same developer behind the Bodylizer plugin (can't remember his name, help) but never got released..

Hi Chris,

thank you...i often look on your page if somethings going on.

I would be very glad if you could tell me your technique after
releasing your guitar library. Maybe i could than help out a little
with some of my techniques (KSP) i use to build my guitar scripts, too.
If you are interested.

All in all i wrote more than 20.000 Lines of code for my guitar library...so
there will be a complex chain of scripts. On the other hand: you have more than 30.000 Samples,
i haven't even started with sampling.

e-guitar Body impulse respone? Help me!
