"Eat Well, Stay Fit, Die Anyway"

Electrical Expertise Required

Is anyone out there a wiz with electronics?  If so, I could use some help with a small guitar project.

My effects pedals are all driven by 9v batteries, but these things eat them like candy.  I could buy a 9v adapter for each pedal, but then I would have a mess of cables and an entire power bar devoted to driving these things.  I’ve looked around online at power supplies for pedals, but figure that building one might be cheaper.

Each pedal is 9v and has between 30 and 100 mA of draw.  What I’d like is one power supply I plug in and then 9v adapter cables that run from that to the pedals.  Since some pedals don’t have 9v adapter inputs, a few cables would have to have the male ends for a 9v battery hookup instead.

So, what would it cost to build something like that from spare parts or from the various buckets at a place like Active Surplus?  Am I just better off buying one of the power supplies many people get for pedal rigs?

    I’m not sure of the process but if you build that, the most likely end result will be fire.

    That’s where the ‘expertise’ comes in. Also, if fire is the expected result, that’s not what will happen. My accidents are always surprises, so it would more likely result in drowning.

    Dude, I could totally help with that. It would be easy, and you would have one of the coolest pedal board setups around.
