Which leads me (us?) to think about the actual GUI of any amp sim, not only S-gear. When looking at ,say, Guitar Rigs fancy panels and elaborate copying of real life amp panels, one looks at certain freeware amp plugins, and so on, and I sigh i disbelief when looking at wish lists such as "add a pedal" add "reverb" add, and then just have to DIVIDE them from the amp, to really point out, that this is a pedal, this is a reverb. When actually everything is software, and IRL real electronics. Just because it looks like an Ibanez Tube Screamer pedal, it lures you, and seduces you into thinking it sounds the same.
Say reverb.
In the early days, a reverb knob was on the amp. Regardless that it was a plate or spring. Now, just because reverb was a dedicated OUTBOARD unit, now when doing anything software, you don't put it inside the amp as just a reverb button, but you just have to do a dedicated GUI display of any rack unit, and show it as a separate item from the amp.
I mean, everything is just electronics, no matter be it a stomp box, compression, effects pedal, reverb, or even cab sim. And walking down that line, in the end,
everything is just software, and number crunching, no matter if it's delay,reverb or distortion or whatnot. To me, "everything" is an effect. Or every effect is part of the amp, software or electronic. No need to MOVE it outside of the amp anymore, just because it once was like that. You just turn on a button or turn a knob and some changes happens to the sound. that's it.
In Guitar Rig, such VISUAL things can be elusive. I did a "mean" patch to rile people up. I managed to get the same sound out of each patch/preset (each of different amp sim, Hiwatt, Marshall Plexi etc) , despite having different amps and eqs and effects. They hated me when I published it at user preset library. You could get the same sound basically. Say if I wanted a Roland Jazz Chorus amp sim to turn out a Mesa Boogie Rectifier, I just put a couple of pedals before it, EQ:d it, and put the appropriate cab sims afterwards. Worked like a charm! Sounded EXACTLY the same. Especially those sounds with a lot of distortion in it (mega gain amps). This isn't possible in any IRL hardware amp of the same manufacturer. Which made me wonder if not all these amp sim companies have the same kind of subcontractors out there who makes the basic sound engine for them, and sells them to everyone (Native Instruments, IK Multimedia, Waves etc) and let them tweak the rest to their specifications.
This is something I just speculates on, and can't be sure about it. BUT IT WOULDN'T SUPRISE ME if it was like that.
Now, these things has slowly DAWNED on me, that - say - Peavey Revalver, THD, Guitar Rig, Amplitube, sounds "kinda" the same, when everything else is said and done. Not really the same, but, kind of. A more generic thing that is a flavor of amp software. The funny thing is, that it ain't so with IRL amps of any kind. Even solid state ones.
