What is the impedance of a Fender Blues Deluxe combo's Power Amp In jack? I'm thinking of recording direct from the Preamp Out jack into a Director DI then reamping at mixdown when I can crank it. Should I use something like the ReAmp (http://www.reamp.com) to change the balanced +4 Low-Z singal to unbalanced Hi-Z? I know it will work for the Preamp In on the amp but am unsure of the Power Amp In. Thanks.
