Just got my Valve Senior Combo today. I'm surprised there's no mention of it on the Epiphone website. I've noticed on a european website, they show one with two inputs (high & low), and claim it's 18 watts. Every amp I ever saw including the one I have says 20 watts, and there's only one input. No problem there, because it works for me. The reverb is weak, but I don't use a lot of it anyway. One thing I do know, I'll have plenty of time to experiment. It's just what I need for what I play.
