Help me, John!!!

Post by JSMidd »

I have two PP2+'s connected to my Pedaltrain Pro.

I know that with the correct cabling, it will power nine of pedals nicely. There are three that I am concerned about...

1. Vox Joe Satriani Big Bad Wah. It's 9V DC, but I cannot get any of the cables to power it up. It works great when I chain it off of my Tuner, though... but I'd like it to have direct power.

2. EHX HumDebugger. It runs off 7.5V, and I'm certain that powering it with 9V would only cause damage.

3. Seymour Duncan Twin Tube... its 16V. How can I make this work off of my PP2+?

According to the specs on the Vox website, this pedal only draws 4mA of current. As long as it is a standard "center negative" polarity (it doesn't say what the polarity is on the Vox website), it should work with any of the supplied standard center negative cables from any output of the Pedal Power 2+ with the DIP switch for selected output set to Normal.

According to information on the EHX forum provided by an EHX administrator, this pedal cannot be ran from a 9V supply without damaging it and is therefore not recommended.

16V pedals cannot be powered via any of our current Pedal Power products. Furthermore, the published power consumption spec for this pedal is 10.4 watts, which translates to about 650mA @ 16V, which is more current than our DC Pedal Power products can supply.

Thanks for the helpful and rapid response. I will find a way to squeeze the respective power supplies for the Twin Tube and HumDebugger into the slots on my PedalTrain Pro where the extra plug-ins are.

I will also re-address the wah.
