Ziller, tube amps and Solid State amps react differently. 100w tube power will overbear 100w solid state any time. It works like this, once you reach the peak power, 100% of solid state, it starts clipping, sounds HORRIBLE and THIN.
When you push a Tube amp past 100% it gets LOUDER, starts breaking up in a warm and pleasing way, and sounds sweet.
As I said, Tubes will outpower SS when push comes to shove.
The louder a tube amp gets, the fuller and more robust the sound, the livelier it gets.
The louder a SS Amp gets, the more fuzzy, thin and lifeless it gets.
Line 6 is SOLID STATE.
Actually, I can honestly say I HATE Line 6 gear, cause in THE REAL WORLD of playing shows and in band rehearsal THEY SUCK.
I actually PLAN on getting a POD just so I can record direct to my computer. It's great for that, or for bedroom or at home practice, but once you throw it in the mix against a tube amp of even HALF the wattage, it gets drowned out.
As ZILLER said, I consider the amp to be an extension of my soul, and nothing is better than driving tubes to their sweet spot and hearing them react to your playing.
Solid State does not REACT it PROCESSES your sound.
For a budget, it's fine, for pure TONE, it's garbage.
Then again, a man who is happy with a black and white TV and has never seen a COLOR one, it's the greatest thing in the world. Give that man a color TV, and I guarantee you that he won't turn the B&W on ever again.
Ignorance is BLISS. This holds especially true to the people who rave about Line 6.
I wish I could be happy with it, but I have seen the light.
Unfortunately, I KNOW what good tone sounds like, and I have to PAY $$$$ to get it. That sucks, but that is just the way it is. I can't settle for less.
