The next step in amp modeling?...

model your own amp - that's actually pretty cool! I'm gonna check it out for sure at NAMM.

Beautiful. That should absolutely destroy the resale value of the Axe.

Let's hope so!!!

I dunno about that, but it would be fun to set there with your own amp and try to make this thing sound and feel just like it. It would be really great if it actually worked!

I highly doubt it does nonlinear convolution since that only works for "weak" nonlinearities, clipping cannot be done using Volterra kernels without a prohibitive number of terms and dynamic convolution (i.e. Sintefex) simply doesn't work.

My guess is that it works the way I used to do amp modeling and has the acquisition/analysis functions built-in. Using the EQ->waveshape->EQ paradigm there's probably a built in sweep generator and mic input. The generator sweeps the D.U.T., measures the response and calculates the corresponding EQs.

I've long since moved away from this approach due to the many inadequacies.

If it is doing some non-linear convolution then it could be revolutionary, but I doubt that will be the case since there hasn't been any breakthroughs in that technology.

I'm still a proponent of physical modeling as that allows one to create anew rather than just copying

I see. So Cliff's 5 year old technology is the way to do it and these new guys are creating a new product with 10 year old technology. Uh huh.

I was acutally thinking about this the other day. I mean, with software like Peavey Revalver, where you can tweak in tube types and their characterstics in the preamp and power stage, why can't developers enable the end user to "tweak" the amp models on modeling amps? Maybe the Axe already does this, I don't know. But, I'm thinking the guitarist could start out with say a Marshall. Then, through some GUI, he could modify the amps character infinitely (somehow). Much in the same way amp designers swap out capacitor values to modify the voicing, gain, etc., the amp would allow you to change the minute details about the amp. The revalver is the closest I've seen to this, but it would be interesting to make it a stand alone unit...

Mind if I join you?

this looks cool, so can you plug into your 5150 and "download " the tone , then use it ? or am I missing something

Dynamically sensing and acquiring the sonic and haptic properties of an amp played in proximity would indeed be revolutionary if it works as advertised. Even if it gets you a starting point to tweak further this could be huge IMO.

My interpretation of Cliff's words (so I could be wrong) is that by modeling each element in an amp circuit (and modeling the amp circuits themselves) and allowing you to mix and match modeled components and circuits and adjust parameters of each, you are effectively able to build your own custom amps without the need for soldering. Revalver does something similar if I'm not mistaken. In this approach, the user has to translate the sonic and haptic characteristics of an existing amp into the Axe-Fx (or Revalver) manually..as the nonlinear convolution is the tricky bit. If Kemper has innovated here, (and allows for similar manual construction of amps as the Axe-Fx) then yes...modeling will be in a new realm.

Thanks for posting this! I'm looking forward to hearing more about this!!!!

You're just worried that that one box could replace all those nice amps you have...

Looks like an oversized car stereo.
Anyway with Peavey Revalver you can actually build your own ampsim. Since 5 years or so. What's the big fuzz?

Revalver is the buggiest, most unsupported software in the history of the universe.

And I wouldn't exaggerate. Not in a million years.

I dunno man, there will some friend of some dude that knows that dude demoing them at NAMM so I'm doubting that's entirely correct.

sounds alot like a sampling synth to me
except you can "sample your amp" then playback the sample with your guitar

The guitar is connected to the tube amp via the Kemper Profiling Amplifier and the mic signal goes back into the mic input of the Profiling Amplifier. By the hit of a single button the profiling process starts and after 10- 20 seconds the guitar player can compare the profiled sound with the sound of the real tube amp. That's it. Simple as that! Amazing!

Well... that's it... the day of the tube amp is almost over...

oh, I doubt that - but it does look like something cool to have around, or at least mess with for a little while.
