I am totally new to modeling. I currently have a Marshall JCM 2000 TSL 100 head. I would like to use my own Marshall on the clean Channel and have flexibility to put HX Stomps post effects in the Marshall's loop. At the same time though I would like to be able to switch to a different heavier amp like a rectifier for the dirty tones bypassing my Marshall's preamp and still be able to use those delays/reverbs in the right spot when needed. I know how to wire the 4cm but I think I'm not building my path correctly on HX edit. Any help would be appreciated.
