HOLY FUCK!
Ran by work, picked up the Jettenuator (which was delivered there, so of course it shows up on my day off), got home and brought it into the house along with a whole bunch of other shit from my parents' place (have I mentioned that moving sucks?).
I set it up, set it to zero, turned on the amp (with EVERYTHING dimed, master bypassed) and then turned the Jettenuator knob up slowly. Damned if I wasn't nailing Van Halen's 1984 tone while using my Franky, but at bedroom volume. I could seriously set this low enough that I couldn't hear it over my AC.
That was damn good!
Makes me wonder if EVH skipped the Variac on 1984.
