aaaahhhh heeemmmm.............the amp models in the AXE FX 2 are so realistic, NO ONE has ever been able to consistently tell the difference between an actual tube amp and these amp models in ANY blindfold test ever conducted. EVER. Any person who claims that they can tell, is really just blowing smoke........period. With fractal algorithms, or whatever the secret sauce, the time is now upon us where the digital has caught up to the analog. Outside of this technology I would certainly agree that tubes are the way to go. After all, tubes are what these new processors are simulating. Also, the AXE FX 2 is dead quiet, while tube amps hum. Now for the real rant.... After 35 plus years playing the guitar, one truth has become evident to me. That is no matter what rig I play through, it always ends up sounding like me. I have become aware that every guitarist has their own unique tone that they gravitate to, and aim to dial in regardless of the equipment. Also, " tone is in the bone ", meaning that ones individual sound, and musical personality are going to be communicated through the player's soul and fingers, much more than the amp. Music is a hearing art. For example, I used to get a shimmering, pristine clean tone from a Mesa dual rectifier, an amp not renown for its ambient chime, because my ears were seeking that sound. Now its a given that the Mesa is a tube amp, but my point extends beyond the classic tube vs. solid state debate. I think it touches on the first law of all music.....that is....." Whatever sounds good, IS good. " When properly understood, that statement should end any argument. Side note: My electric guitars are now a pair of Custom 24s, and that because of the wide variety of sound these tools make available. AND.....I still have the option of a Groove Tubes Trio preamp, with a Real Tube spring reverb in my signal path, and probably always will.
