They all sound great, this biggest suprise being my 6550 loaded Ampeg. I had heard all sorts of sterile stiff sound opinons on that tube. I was very suprised when I plugged that amp in. That amp is extremely dynamic.
I have learned in my musical messin, that there is no singular truth when it comes to what is the best.
