My Mesa Boogie Mark IIb has a Preamp-Out / Power Amp-In 1/4" jack.  This is separate from the amp's effects loop which is before the master volume, and this is only one socket so, connecting does not disconnect the preamp from the power amp.

So the question is, if I connect the Pod Pro out into this connection would the Amp's preamp interfere with the Pod Pro driving the poweramp?

Anyone ever try connecting Pod Pro to a Boogie Mark IIb?

Thanks.
