Which part of amp is the most difficult thing to model ?

[mr_fender]

The different textures of Tolex...

Don't forget grungy, smoke and beer stained tweed also!

 

[groovenut]

when the crystal lettuce whilts, you get the brown sound.

 

[Gamedojo]

...to answer the question properly:

I would imagine the SPEAKER is the hardest part to model.

Crystal Lettuce is right. Subtle idiosyncrasies are a huge challenge, with regard to how a tube amp reacts, to whatever signal
is being thrown at it, how hot, bias settings etc.... Cliff has raised the bar here. I mean think about the stability of electrons,
bouncing off of the plate in a typical, say, EL-34, then recreating that in a digital domain, which is static and inflexible, as far as
audio goes. Ughh.

The grill cloth.

Then the tolex.

 

[maxdown]

The little plink sounds after it's turned to standby

Seriously ... I don't understand analogue circuits nevermind the conversion to DSP ..... so I try not to think about it.

 

[Smilzo]

The grill cloth.

Then the tolex.

The dust on them.

 

[ps43203]

Yes to all, and don't forget the 50 year old nicotine glazed, vintage capacitors, the sound of a 1960's drake transformer, ready to fry.

 

[Char2000]

The flux capacitor

When does the cat die?

Schrödinger?

 

[kavoo]

Preamp ? Power amp section ? Someting else ?

The part that sounds good...to everyone.

Schrödinger?

More or less...but never both.

 

[steadystate]

The tube smell. No one has done it yet. It's the only thing I still miss.

 

[Rex]

The tube smell. No one has done it yet. It's the only thing I still miss.

So true. Though I don't miss the smell of a hot amp that's been steeped in bar fumes.

 

[ps43203]

Schrödinger?

The cat is alive and well, if you ask me.

 

[Stratoblaster]

Hmmm I'd say it would be how to model the demodulation of a taxi/CB/AM radio signal on a poorly shielded amp/cable making it the worlds loudest AM radio receiver...it's creepy when you hear voices coming thru a 4x12...
