If you want to use both the amp's preamps and modelling then the only real way to 'have it all' is to use 4CM. Per the manual here http://www.marshallamps.com/handbooks/pdf/vsmk1.pdf ==> , the loop on the 8080 is parallel but there is an effects mix control also. When 100% clockwise the loop is effectively serial so 4CM should work. This is also how it works on my Marshall JVM.
If you are feeling brave then give 4CM a go ... details here (amongst other docs on this site) ==> http://line6.com/support/docs/DOC-2522
Otherwise the only way I can see you making this work is to have the HD500 in the loop but then use the second input on the HD500 to connect a lead straight in. To use the Marshall Preamp you would use the lead plugged into the front of the amp. To use the modellled tones you would use the connection to the second input. This is a bit of a pain but you could make it a little easier with an A/B Switch.

I'm affraid it won't work. If I'll set the mix control to 100% wet, there won't be ANY signal from preamp. Look into the manual of your JVM, there's a hint telling that with no effects in the loop mix control act like an additional volume control. If I connect my HD500 into the loop with 100% wet, I'll get 100% signal from POD and 0% from preamp.
Looks like I will have to stick with 8080 alone for some time and hope that I'll get the money for planned JVM as soon as possible (and then connect POD to it using 4CM).

I think you may be misunderstanding the function of 4CM and the function of a parallel loop.
With a parallel loop, the Effects Mix control balances the amount of clean signal output from preamp againt the amount of 'effected' signal that goes through the loop. The purpose of a parallel loop is to allow pristine and effected signal to be mixed and reduce the impact of tone-suck from effects units. A Parallel Loop with the Effects Mix at 100% becomes a standard serial loop !
With the Effects knob set at 100% this means that all signal from the preamp will pass through the effects loop. None of the dry signal from the pre-amp will be mixed in. This is a good thing for 4CM as you want all of your signal to go through the Pod. The full preamp signal gets 'Sent' by the amp to the POD FX Return and then 'Returned' to the amp via the Pod 1/4" Output. This is the bit of the hookup where you would want to put your modulations and delay-based FX.
Trust me on this, like I say, I run 4CM with the JVM regularly and this is how I set things up. It works. Perhaps the doc here might help you get a clearer picture of why and how this is working. http://line6.com/support/docs/DOC-2523
The advice from the JVM Manual is good if you have nothing in the FX Loop cause the Mix control acts as a volume control when there is nothing connected to the FX Loop but it does not apply in this situation - you have the butt-end of a Pod in the loop.

OK, now I get it.
Just checked - with 100% mix it really looks like loop behaves as serial and 4CM works excellent. Many thanks mate, you helped me a lot! :-)
