Amp Modelling - How does it work?

[Zyklons Eye]

Hallo everyone!

I've to write an essay about amp modelling and how it works, software and hardware. Does it work like a convolution reverb? Has anyone some ideas about that or could give me some links? Would be very great!
Maybe someone knows a book where amp modelling is explained.

If anyone has some informations about amp modelling, please let me know!

Thanks,
Zyklons Eye

No. Convulsion is a linear operation. Amp modelling is much complexer, because of it's nonlinear behaviour.

As a first approximation you can use a nonlinear characteristic curve of a single tube.
This gives you some kind of distortion.
But real amps are more complicated, i.g. the voltage drops by using tube rectifier, the amplifier stages interact, there are different frequency responses, the output transformer produces distortion, Etc.pp.

try calling Line 6 Tech Support... I don't know if they will take the time to explain it, but it might provide some results.

POD etc manuals might be worth a look. Admist their talking themselves up, there is a little insight into their approach.

Also, check out some of the articles at Universal Audio's site http://www.uaudio.com. They make the awesome 1176, Pultec, and Fairchild plugins, and their Webzine has some interesting, if brief, articles about modelling classic hardware in software (check the archives, especially the "Ask The Doctors" column). They also make the Nigel amp modeller, so there should be some stuff on there regarding your specific area of interest. I would go and find them, but I'm busy researching a much more boring term paper.

Thanks for the fast reply!!

I'll check the hints!

Behringer wouldn't tell me anything about the V-Amp,

You'd think that the main manufacturers would keep their amp modelling procedures as close guarded secrets. You could check with the developers of Guitar Suite. That's a free VST set of guitar distortions/effects/amps and the guys are all scholars.

after hearing a v-amp, I wouldn't ask them anyway





sorry. I coudn't resist a little behringer bitchin'.
