While I realise it’s more options than any out there that’s not my point in this post,
I know if I turn knobs on a real amplifier it changes its value resistance
what I meant was if it was if the fundamental values of the potentiometer , capacitor and resistor were changed
For example on an amp’s bass/treble circuit section it had ...to...
Pot=100k to 150k
Resistor=5K to 7k
Capacitor=100nf
It would change the bass ,middle treble’s frequency response , (q values , band width etc..)
I’m personally not an expert on electronics/audio circuitry so pardon me, but this also would be a cool way to understand how an amp works
Not my point. I understand what you are asking but I don't think you are following what I am saying.
Mind you my tube amp circuit knowledge is, granted very rusty (haven't modded a real amp in years, haven't needed to with the Axe)
For instance if you go to an Amp block with any amp model, to the Preamp settings you find Low cut Freq. Now in Axe Edit, or the Axe III display it shows as a knob, and you can change the frequency. But, IF this were a real amp, to change the Preamp low cut freq, you are changing a capacitor and resistor value. Triode 1 Plate frequency is shown as a knob, but again you are really changing a capacitor and resistor pair that produce that (if it were a real amp. Basically, almost everything on the Amp Block NOT on the Authentic 'tab', and some of the Ideal 'tab', is represented as a 'knob', that is setting a result, that requires changing capacitor and resistor values, in the amp circuit, if it were a physical amp.
Granted Axe Edit for the Axe II, I seem to remember more settings to be more of the change the capacitor value types.. But, now, with Axe Edit 3 for certain, the parameter/setting is more descriptive as to what you are changing, from a player/tonal/feel perspective. Most guitar players know what more or less SAG is and does, and could care less that to achieve more or less requires changing values on components like changing a ss rectifier to a tube one, or adding a series resistance to the ss rectifier, or changing the value of the filter caps, or different transformer windings etc. Some or all of which is happening in the amp model with just a couple of parameters.
In fact, on most of the parameters, on most of the Amp BLock Tabs, what you are getting is variable value Capacitor and resistors at key locations of the AMp circuit. That is what the little knobs are in these tabs Some are truly just a variable value Cap, or Resistor, others are pairs of a Cap and resistor, others are multiple componants.
And in your example above, you can do, just not the way you describe. WHen you change the tonestack type in the preamp tab of the amp block to one of 119 other amp's tonestack, that is what you are doing. Of course, you would have to research what the different tonestacks from these amps are actually like. Might be nice to know that the Ampeg SVT (Axe SVT Bass) used a Baxandall EQ AND what that does.
Most axe users are, imho not going to want to the kind of granularity you are asking about. I wouldn't mind. But we would be a minority. Adding it as another level in Axe Edit (i.e. toggle on or off), imho, makes Axe Edit too cumbersome to support and upgrade. Again, imho, it would be an additional tool added.
