Adding to Johnny's link and thinking about your gear
You'd want a humbucker
I'd try and dial in the Zoom to get a Marshall-y tone (a tube scream/marshall guv'nor in front of a Marshall JTM w/ 4x12 seems to be the default rig to model).
I'd use the amp as flat as possible (no gain & eq from amp) to let the Zoom do as much modelling as possible without the amp colouring it (Multix like full range amps). Though this may be tricky, guitar amp speakers colour tone, it's part of their design - you'll find a decent set of headphones will likely get you closer.
But that meaty sustain without a humbucker...? Possible, but probably not as satisfying.
