Well, let's get back on the Tube 800 topic now !!!
I tried it last evening at my rehearsal and I cannot be more satisfied !!!
The head is really different from my former LMK II as it has more 'balls' and more low end. I like it a lot and fits my personal taste. My Lakland DJ 4 has never sounded better and defined. All members of the Band noticed the difference in tone, being warmer. The trick with this head is to adjust the Tube/solid state control knob at 50-50, this is where the real power of this machine will be noticed and its magic will surprise you.
The Mute switch is a great addition as well as the second input. The VLE and VPF are the best invention ever and could not liv without them !!!!! The EQ section is as always really sensitive and easy to get the tone you want.
I really dig the Tube 800. I ran the 410/210 HF combination and the extra headroom I got from the 800 watts helped as well, when needed.
Definitely a great amp, in my humble opinion.
