I added a couple of mini pedals (TC Ditto and TC Polytune Mini) to my PedalTrain Jnr bringing the total to 10 pedals so I needed a couple more power slots on the PedalPower 2+. I could have just gone with a daisy chain from one of the PP2 slots but I wanted to keep the board as neat as possible. After investigating making up my own splitter cable from parts I came up with this much easier solution. I ordered two of these daisy chains from eBay for $5 each:
9V DC 1A 6 Way Guitar Effect Pedal Daisy Chain Power Supply Cable
The quality of the daisy chain is just fine.
I created two splitters from each daisy chain by just snipping off the unwanted leads with sidecutters close to the plug to leave me with two 2-way splitters of just the right length for the board. This works particularly well for two pedals from the same manufacturer that are mounted next to each other on the board. Much neater than adding a full 6 or 8 way daisy chain to the board.
You start with a full 6 way daisy chain (f = female, m = male)
f---m---m---m---m---m---m
and end up with two 2-way splitters (and a useless female end):
f m---m---m m---m---m
I use one to power the Ditto and Polytune and another for the Flashback and Hall of Fame. I still have one unused daisy chain
cable which I'll either keep as is or hack it if I replace one of the larger pedals with two minis.
Note that I'm not using the female end. I'm simply going straight from the centre male plug into the PP2 out to two male plugs to the pedals. The fact that they are all right-angle plugs keeps the whole thing really neat and tidy. Two splitters for 5 bucks!
