Well, I don't know how much this will help, but I had a Marshall powerbrake that I used with a JCM900 head and a TSL100 head for a while. I'm not sure it really helped the tone all that much. I have since sold all of the Marshall gear for a Soldano SLO100, which is the ultimate amp for me,,,but I don't desire an attenuator for it. Why? Well, because turning up a tube amp does make it sound better, fuller, warmer,,,,and the SLO is no exception,,,,but I once read that it's more than just driving the power section harder, it also has to do with how the speakers react, the air they move, etc. So using an attenuator may improve your tone if you will still be playing quite loud anyway (i.e stage volume), but to my ears, it will never equal the sound of truly, naturally playing louder. I currently use a Gmajor FX processor in the loop of my SLO, and use its level control to allow me to turn my SLO up louder without all of the volume..............and it helps a bit, but it always just sounds better when you really push those speakers and play loud. For live, I would say try just playing through half of your cab (then you could turn the amp up more with less overall volume),,,but for at home, quiet recording use,,,you might benefit some, but there's nothing like the real thing. Crank your tube amp and cover the miked cab with blankets....that might help. I think most people will agree that cranking your amp and heavily leaning on an antennuator to make it really quiet doesn't exactly create magic.
