I'm going to look at and play through both of these amps this weekend. After a bunch of internet "research", I feel that both will meet my needs of tone and volume. I've never played a Super Reverb, and to my understanding, 1981 means that it's not a reissue? I have played a Twin amp, and I liked everything about it, including the Gain channel. I liked everything except the weight, but either the new amp or my Peavey C50 410 will live at church, so I won't have to move it very often or very far. I'm going to play both of them with my guitar and pedal board and bring home the one I like most. My concerns are whether these things are reliable, and also, regarding the loudness of the two amps: 45 watts/410 vs 100 watts/212, which is going to peel paint better? Any bugaboos I should be aware of that might lead me one way or the other?
