Boss GE-7 with the sniper mod. The least expensive way is to buy a used GE-7 off of the bay and send it for the mod. Otherwise Tonejam charges about $145 last I checked for a new modded pedal. He recently changed his website though. You can probably get more info over at guitargeek.com
10 highly responsive bands, super silent performance, 9 memory slots to save your favorite settings, it's everything anyone could want in an eq (except for the fact that it's a bit of a tonesucker in bypass mode. I never turn mine off, though, so it doesn't bother me).
