My SKB-PS-45 Profesional Pedalboard has a filtered power strip (with it's own 15 Amp breaker), spaced for 3 Wall-Warts and will also power up 8 9v outputs with it's own filtered internal 9V DC power supply. That means I can run 11 pedals and a volume pedal. (Being I play bass, I'll never have to worry about filling it up.)
It will run stereo pedals and easily feed 2 amps. The built-in effects loop can be tapped into for a seperate loop or run the D/I or both. It also has extra taps to tap into on it on both channels. (I run it in Mono, so I have double ins and outs on it to play with.)
The case has a reinforced locking top that's so tough, you can literally JUMP on it and you can't hurt it. The power cord on it must be about 12 feet long and is thicker than most drop cords I've seen.
Because it's grounded and shielded already, when I run it off the front outlet of my Furman Power conditioner in my rack, everything I have is all in phase with each other and I don't usually ever have to worry about hum coming thru the line. The only time I did, it was a bad wire and there was a lot of neon signs in the bar. I changed the 1 pedal cable and the hum was gone. (my guitarist however was going NUTZ, dealing with the noise from his set-up.)
SKB gives this unit a lifetime guarantee on it. It's not just a pedalboard; it's self contained case for all your effects. (I think it's also water-proof as well, but I'll have to check the Specs on mine.)
I got mine at a deal and it was still about $200, so they're NOT cheap. But if you add the cost of a powerstrip and line conditioner, breaker, the DC power supply, 9V pedal cables and 3" wide velcro roll into it, it really isn't that bad of a deal. YMMV.......
