Here are my pedals

It goes guitar to bypass pedal, which goes out to the reverb and amp. The loop goes fuzz factory, volume pedal, DMM, small stone, dd-5, loop station, and back to bypass pedal. My problem is both my small stone and DMM cut the volume about 25% when I click them on. however If I just use one. like I go guitar cable DMM cable amp. I get no volume drop. None of my other pedals do this, and I really want them to work in this order, especially the DMM. it has to be after the volume pedal. What the fuck is going on. I'm mad

I may throw my guitar out the window
