What Boss pedals do you BCB6 users have onboard? I'm running a TU2 as a power source (and tuner, of course)->AC2->GE7->CH1->PH2->DD5->amp. A lot of times I'll run this through the amp loop, sans AC2.
In front of the BCB6: Guitar->Crybaby->OD-20-> to the BCB6 or amp if BCB6 is in loop. Occasionally use a DS1 and a HM2 in place of OD20. Also have a Boss ME50 unit. Sometimes I run that into my junky little PA.
