As far as the OP, I bought a bunch of 1>2 and 1>4 barrel splitters from ebay for about $3 a piece. You just have to try it....you'll be completely safe as far as mA, but as mentioned, some pedals don't like sharing power supplies. I also keep my digital and analog pedals on separate isolated outlets. Currently running 14 pedals off of a single VoodooLab PPII using a bunch of splitters. Only problem I had was my Fulltone Clyde....nasty buzz when daisy chained.
May be so, I've never tried it, just going by what VoodooLab states in their manual. Not sure how you can rig series or parallel from two sources. Typically that implies from one source you can either wire series or parallel like in speaker wiring. I have no idea how to do such a thing from two sources combining.
They state it doubles the voltage, doubling the mA is of little concern. The typical basic combiner plug only works to one issue, doubling volts. I do not think confusing the issue towards complex wiring Gerry rig helps trying to teach uninformed players on the basic issues of daisy chain and isolated supplies. They do not get the basic much less confusing them on more knowledgeable options. I just use high current or high voltage wart supplies for the ones a brick cannot produce. Everything runs off a Furman, a another thing less experienced players run into is using multiple wall socket sources, that simply provides multiple paths to ground and presto ground loop hum.
Every Fulltone I have had reacted terribly to power supply issues even good ones. Every time I increased the voltage on the Fat Boost to what Fuller claims it can handle the hum got worse. First thing they tell you is "remove the pedal from your chain, use a soldered end cable and a new battery and see of the pedal still hums". This is a test of a pedal??? Of what use could that possibly be?
It's because of the customer service and refusal to admit some of the pedals have a noise problem I stopped using Fulltone pedals. I noticed that Robin Trower who uses Fulltone exclusively uses batteries in all his pedals, I thought man that is really old school low tech, then I realized he is just trying to keep the pedals quiet.
