What is the best sounding amp you ever played in your life?
Me, I am not sure. I guess it would be the Vox AC30 Collector's Edition. Man, that was some oomph in that aamph!
Edit: I forgot to mention the Dr. Z Maz 18 Jr I played in Portland, OR. It was stunning. Fantastic clean tone, and it was also possible to get soaring overdrive tones at low volume.
