Awesome that you back up his assessment. I totally agree and appreciate this concept since my old 150w 1x15 combo, seemed like it could almost reach the same volume as the Rumble 500c (no extension) that replaced it when it bit the dust. That's why I hoped a 4x10 might be enough, but since a 4x10 is usually equated to a 1x15 in volume, I guess I should have expected as much. I guess I just really want the 100T to be enough with a 4x10 that the tone plus the all tubes will give a better perceived volume for the rare occasion it is an issue and maybe a 100T through 2 4x10s down the road will be a nice boon. Based off my time with the 2 (Super vs 100T), it was close enough, that I really want the 100T with it's silent mode, but this is slowly turning into a side career and I've only just recently made enough to substantiate the purchase of 1 amp and 1 cab. Right now, I can't afford to buy the wrong amp. I haven't had a chance to play them through the actual 4x10 neo cab, only a rumble 2x10 extension cab, where the 100T does seem to almost have a louder (at least perceived) push compared to the Rumble 500c which might be all the help I need once I get the 4x10.
