we need to do the blindfold test and just a Plexi marshall 50 thru 25w, 4x12, greenbacks .. all on 10! perhaps at one of the " monthly meetings " we could do that in real time. I listened real closely and from what I think I heard all were pretty much the same! If that's true then go to the least expensive and the corporations take a hard hit. I must say thou I can tell a good PAF a mile away ... due to the bloom and 3D nature of their sound. The early Plexi's do not hurt your hearing at 10, all day long! Of course, in case there's a fire there would have to be lots of " Suds " around, just in case .... Hmmmm maybe an old AC30 too
