I've used an Airbrake for a couple years, and it's really changed my perspective on using attenuators. When I'm using it, I forget that it's in the chain. That's probably the best compliment I could offer for it. It's also nice not having to mess with AC cords, heat issues, and matching impedence. Ken Fischer knows a thing or two about amps, so it should be no surprise that the Airbrake works so well. Hope you like it.
