i've had an SKB powered pedalboard for years, during which time i gradually gravitated towards all 9v pedals. it powers up to 6, and came with a few different leads.
i have a male-to-male lead now for the RAT which worked perfectly, it was good of SKB to be so thoughtful... my tremolo, phaser and chorus all take the standard lead supplied. it had a 9v clip lead too, so originally i'd drilled a small hole in the side of my vox wah and had it hooked up permanently, but i got a bad noise so i started using a battery on it. so as long as i remember to unplug my guitar from the vox after playing, everything runs forever maintenence-free.
