Ok just checked out the Alesis Multimix8 so started this thought bubble. (but you lose some bits/gadgets but IMHO this will sound better so maybe start like I'm suggesting and work things back in later).
Guit > A/B Splitter (A / JMP1, B / MP1). JMP1 L/R > Alesis MM8 line in chan 1/2 (pan L/R), MP1 > Alesis MM8 line in chan 3/4 (pan L/R) > Alesis MM8 out 1/2 > (Hush here if you want ? and DOD EQ if you want
) > DCM200 > cabs (stereo cab ?).
Now for FX, chan 1 and 3 Aux A and chan 2 and 4 Aux B to MX200 L/R in, MX200 L/R out to QV L/R in, QV L/R outs to stereo channel 5/6 (don't tun up Aux A or B on this return or will feedback). Adjust MX200 wet/dry so there is still enough dry signal for QV, run QV full wet and mix it all back in via chan 5/6 fader. (or don't use MX200, just QV full wet but connected this way). So this preserves analogue stero path all the way with digital FXs mixed in in parallel.
Boss GE-7 EQ >BBE Sonic Stomp could go in front of the A/B switch ? or in either the MP1 or JMP1 loops ?
Note: The channel vol level will affect the Aux B send level as it's post (ie post fader), Aux A (designed as a monitor send) wont be affected by channel vol as it's pre fader, but once adjusted won't matter as your not changing (continually adjusting) the faders/vols like in a live mix.
