Well, there is some post production involved with those clips, I have to say. The speaker sims of the TLab aren't that great, but overall the sounds are superb, very versatile. This modeler has actually given me back the fun of guitar playing.
I recommend to exchange the stock EH12AX7A with a JJ one - gives more warmth and depth indeed (ensure to use the highest spec ones), and the presence should be used with caution on the Soldano model...
Meanwhile I'm not touching it so much, as I'm back to playing loud (band assignment:), which means less effects and a valve head (ENGL Screamer). At the moment I only use the Engl, a RMC3 Wah and a T.Rex Replica Delay. These are all finest components and give a nice sound indeed - however it's much harder to capture than the Tonelab sounds.
I would be wondering actually what it would be like to play the TLab directly into the PA system...
