This brings up something interesting to note. I too spent endless hours building and tweaking several amps. And the funny thing is, it was much like having a modeler and endessly tweaking dials but instead of dials it was soldering or clipping in various resistors and caps and altering circuit pathways. I would leave the chassis sitting on top of the combo cab with the speaker plugged in so i could tweak and listen in real time for months on end tweaking it daily sometimes for hours ! granted, part of that was almost as much a game to me as trying to nail perfect tone. But it's funny you mentioned this because that is exactly what a modeler gives you....the ability to alter the tone in far deeper ways than with the basic gain/vol/bass/middle/treble fine tuning controls (because thats really all the are) on a typical tube amp. Just like i did for years with tube amps and a soldering station, but with a dial and buttons and LCD. Thats a point i've made here before....that a modeler is like a blank canvas and a tube amp is like the almost finished picture that the designer brought to the point you have to do very little to finish it. But the almost finished picture (the tube amp) is going to look the way the painter intended leaving the owner very little left to do to change it more than a tad. A modeler is like a blank canvas and a set of brushes and colors and the rest is up to you. It's no wonder many would rather have a tube amp because not everyone is willing to put the time and effort in when it's so much easier to let someone else to all the work for you. But there are also benefits on the other side and some of us find them worth the effort. To be honest, maybe the biggest reason i love the mustang is the fact that i don't go crazy wondering why my amp sounds like cr@p one day and great the next. I LOVE the consistency i get where i know every time i plug in it's gonna sound the same. For years up until i got the mustang i never could figure out if it was me, my ears or whatever, or the amp that caused that. Now happily I know the answer.
