I currently have 3, but only 2 of them are wired up and get used Live. The 3rd is my "Fun" board consisting of pedals I don't get to use in my band, but like to have until I find a use for them. I consider the boards as one big board, like a modular setup, in which the first board is for general tone shaping, and can be used by itself with no effects, the second board adds on to the first for the effects I use with my covers band, and eventually the 3rd board (when it's finished) will have the mad stuff that will plug onto the 2nd board for all kinds of effected crazyness when jamming and doing originals.
Board Number 1: A small Diago Gigman, just for the bare essentials so I can grab n' go if I don't need effects. This consists of my X2 Wireless receiver, Mojohand Cream Pie for a bit of dirt, Korg DT-10 tuner, and a Visual Sound Volume pedal (for matching the outputs between my Passive and Active basses).
The second board is my main effects board, it's a Pedaltrain Junior, and the Diago plugs straight into the front end of this board which consists of Boss OC-2, Xotic XBlender, home made Swollen Pickle/Big Muff fuzz clone, Crowther Prunes and Custard, Analogman Chorus with Deep switch, and an MSD Earthquaker Bass Wah. Still experimenting with the order of things, but should have settled on a final setup soon.
My 3rd board is the largest, being a Pedaltrain PT-2, and has on it (not in any particular order as it's not wired up): Original Mutron III, Original Digitech WH-1 Whammy, Montgomery Appliances 77 flanger (A/DA clone), Atomic Echo Clone (original Way Huge Aqua Puss in a different enclosure), Catalinbread Serrano, Catalinbread Valcoder trem, EHX BassBalls (I bought this to perform the internal trimmers->external pots mod, but haven't got round to it yet).
Haven't got any pictures of this setup yet, but if anyone would like to see it all I could take some
