Alright y’all, this rookie here needs some advice and pointers regarding multi effects pedal and tube amps.

A little background…

I got my first tube amp about a year ago, love the thing. I slowly built a pedalboard with the basics (tuner, compressor, MXR classic distortion, tube screamer, holy grail reverb, Joyo delay, modded GE-7 EQ, JHS black box, chorus…). But I also wanted to start experimenting with multi effect pedals and patches, so I got a GX-100, exclusively to play around, tweak effects more in depth and see how it would be to have a one stop shop for all effects, albeit I have zero interest in amp modeling, I’m happy with my JCM800, just thinking about effects here.

I’ve never messed with multi-effects pedals, so here are my concerns…

1). With the GX-100 set up in a 4CM, I noticed that immediately all knobs on the amp itself are disabled, I’m thinking this is normal , since the control now lays on the Gx-100, not the amp itself (right?). However, isn’t there an option with multi effect pedals were I can still keep the raw sound of my tube amp and just feed it effects from my multi effect processor?

2). Considering question number 1 above. Is a multi effects pedal intended then for use on SS or modeling amps instead and not tube amps? Is it a complete disservice to a Marshall JCM800 to go and hook a multi effects processor to it?

If I can’t preserve the original base tone of my Marshall with the multi effect processor, it seems kind of a waste of time, the way I see it it would be stupid to hook a ME pedal trying to model an Amp that I already have, just to add effects to it. Am I missing anything? Am I way off here?

Would I be better off keeping the pedal board connected to Marshall like I had it and just get a modeling or SS amp to connect the GX-100 to?

I don’t gig, just play to backing tracks at home and occasionally get together with friends to jam together, but nothing serious or advanced...

Any input would be greatly appreciated!
