Here are my 3 DIY boards (and some pedals on the floor), installed in the practice room, feeding 3 rigs.
The main board:
Bass -> Dunwich Doomfinder -> DOD Meatbox RI --> wet goes through the 2 Aggies into Sunn 200s/Acoustic 301.
Meatbox dry --> EFE Dope Priest --> Monolith Oracle --> DIY Silver Rose --> Hilbish Pessimizer --> Blackblood (=Dunwich Fuzz Throne DLX) --> Industrialectric Incinerator DLX --> Industrialectric Echo Degrader --> Industrialectric RM-1 --> Boss Flanger --> Boss DD7 --> tbc
DD7 output Left --> DIY Megalith -> Creepy Fingers Supa Fuzz with extras --> DIY Octave Fuzz --> DIY Polaris --> DIY Life Pedal/Hyper Fuzz --> Dunwich Wizard Fuzz --> Laowiz Foxx Tone --> DIY B&M Fuzz --> Dunwich Spatial Rift (Muff+Meatbox) --> RW O)) / 2x15"
DD7 output Right --> DIY Sputnik II --> Dunwich Temporal Rift --> Dirge Double Fuzz --> DIY Systech OD --> DIY Peach Fuzz --> Buzzaround --> DIY Life Pedal / Coda Black Hole --> Musicman HD 130 / Ampeg 6x10"
To hear and feel all this, we have in total: 4x EL34, 4x KT88, 6x10", 2x15", 1x18". (the Peavey 2x15" was replaced by an Ampeg 6x10").
The main board has stayed like this for a long time now. But I regularly swap out pedals on the left/right boards.
