Before getting into this I'll explain my set up..

Guitar goes through Line 6 G30 wireless system into the first half of my pedalboard (wah, overdrive/distortion) before the amp. In the FX loop I have my chorus, delay, reverb and clean volume boost. All the pedals are controlled by a true-bypass looper.

For some reason whenever I activate a loop that contains any of the pedals in the FX loop, there's a pretty considerable volume boost.

The pedals are an MXR Analog Chorus, Strymon Brigadier, TC Hall of Fame and MXR Micro Amp. The Brigadier and HoF have the most noticeable boost, the chorus isn't quite so loud.

Is this something to do with the long(ish) cables involved in my FX loop? I'm totally clueless, and it means I end up leaving my reverb on nearly all the time..

Does it happen with both of your amps?

Is there a send volume or signal strength knob on your amp(s)?

Is your FX loop tube controlled? If so maybe you have issue there.

Is your volume pedal on?

It seems like you left out what your loop switcher is. Maybe that is affecting things?

Do you have the micro amp on with the rest of these pedals? Because that's literally what it's supposed to do.
If not: Does your amp have send/return level control for the fx loops? Try lowering them if so.
Charvel So-Cal (SH6TB/N, killswitch), Jackson RR5FR (TB6/Jazz, Drop C). Joyo pxl pro.
Loop1=Crybaby from hell, Boss PS-5, Seymour Duncan 805 or Green Rhino, EQD Hoof or Earthbound Audio Super Collider. Loop 1 into ISP Decimator II.
Loop 2 (FX loop)-Line6 M9, TC Spark Mini. Loop 2 into mxr 10band. All into a Peavey Triple XXX 212, Ibanez IL15.

I've not actually tried it with anything other than my JCM900, long story short, all my gig gear lives away from home as I don't have the space to keep it at home.. So I don't know

There is an "Effects Loop Level Control" on the back of the amp, I can't believe I never thought to try that Although, the guitar signal is going through the FX loop all the time, even when I'm not using those particular pedals so surely that wouldn't make a difference?

I don't think so..

I only use the Micro Amp for a volume boost in solos, so no usually not.

It's a hand made thing built by a guy here in the UK, it's completely passive unless you connect power for the LEDs.

When boosting for solos and certain other lead parts, yes. Otherwise it sits in its loop minding its own business

I thought, maybe these pedals are buffered and that's what gives the volume boost? If I need to put a buffer somewhere before/after my FX loop cables to keep the volume consistent, maybe that's what happens when I engage these pedals??

unplug your pedalboard, and try one of those pedals in your loop by itself. run the guitar straight into the amp, no effects out the front. if you don't have the volume boost, then start adding stuff back in. process of elimination.

if the boost still happens, then it might be a little more complicated. try what i suggested first.

Turn down the effects loop level before going through all the trouble of processes of elimination. You are probably using line level at the moment when you should be using instrument levels for them pedals. I would turn it down all the way 1st and then bump it up as needed till it sounds best to you for your setup.

I ended up turning the FX loop level all the way down, and it's all balanced out. I'm not sure how that works, but it does!
