Doesn't the POD have an FX send loop? If I understand correctly the POD allows you to send the signal through the FX loop and the assign the loop to hapen pre FX or post FX. This would allow you to process the signal with the POD then send that processed signal to the Wah and back into the pod to be sent in stereo to your other FX unit. I pretty sure the POD XT works this way. I not sure however it hte older POD (pre 2.0) works this way.
