For playing in a band: Archer, Black Zendrive, and a Reverb (Digitech Polaris is on the board, atm). Playing alone / practicing, I would add a looper (Boss RC-2) and loose the Zendrive. I switch around all the time, though. I try to keep no more than 5-6 pedals on the board, including here the tuner and the looper. BJFE Honey Bee is another one is often stacked with the Archer and works exceptionally well with SGs.
