I guess I don't understand the db range that is stated for the AirBrake.. maybe somebody can explain. After all, if I'm at 100-110 db level without attenuation, -1.8db per click wouldn't be particularly noticeable, but it is. So that figure might mean something else?? Is it stated as the effective reduction in sound level or as a change in speaker/cabinet rated sensitivity?
I used my Airbrake on stage with a Marshall JTM45 last weekend for the first time. I was surprised that I settled on 1 click for the best attenuation setting that evening. I would have thought I'd be on 2 or 3, but the first click was perfect. Diddling at home I'm on 3 or 4 with my Z28. There's more going on than just dropping 1.8db because that amp is mighty loud with no attenuation... hmmmmm??? I'm wondering if it changes the way the amp reacts to the load as well, ie. I am interpreting volume settings with the "feel" I normally associate at a given amp setting. The attenuated amp feels less stiff, which is what the amp feels like when it's cranked and the tubes are cooking.
