OK, thanks for your advices.
I just have one more question.
We often hear that to get a nice sound with a tube amp, you must push the volume and the gain, so that the tube really delivers a nice sound.
But with a transistor amp, either you play at a low or at a pretty high volume, it sounds more or less the same.
Am I right for the transistor part?
Well, except for the 'need to push a tube pre or power amp to sound good', I agree.
Put another way, many people like tubes because you can push them and they 'change' at different input levels and volume levels, ranging from quite similar to a good quality solid state amp when not pushed hard, all the way through massive grind and growl when pushed.
On the other hand, many like high quality solid state amps due to the fact that they do maintain a relatively constant tone up to their wattage limits (and solid state watts have become so inexpensive that you can get so many watts in a lightweight amp that you would never, ever come close to reaching their limits).
The unique thing about the TC amps is that they have a kind of 'tube rig through a sealed one way cab' emulation built in, which makes them sound a touch like a tube amp pushed a bit all the time (i.e., the low end is a bit compressed, and on the units without the variable hi pass (called tweetertone I think), a warm, rolled off top end.
