I'm thinking about buying the POD HD500.  I want to use it as an effects board for a stereo amp configuration.  The two amps that I have are a Mesa Boogie Rocket 440 and a custom Fuchs ODS 50.  I've downloaded the manual to see how you'd set up the HD500 but it doesn't show you a diagram of where in the signal path the HD500 should go.  Should it be between the guitar and the input to the amp or using the send/receive input/output  in the amp?  Does anyone have recommendations/suggestions?
