As long as you do not go OVER 9.6 volts you will not damage your pedal. Even then, there is A SMALL AMOUNT of headroom to protect the pedal, but you shouldn’t depend on it.

There are a few things to consider though.

First, as Administrator said lots of “daisy chained” power supplies will allow pedals to inject noise into the system, and digital pedals seem to be the worst offenders. So, test it with the Pitchfork plugged into the power with all the other pedals and then again without it plugged into the power. See if there’s a difference in your setup. If you notice the Pitchfork adding noise, try running it on its own dedicated power and see if that makes it go away.

Second, these digital pedals can be a bit finicky. They are basically little computers that have to go from being off to booting up in a tiny fraction of a second. If the power supply doesn’t ramp up to full power (I think that’s calle the slew rate.) fast enough, the pedal might come up in a weird state, like not responding to the button, knob turns, etc. Again, if the pedals acting funny try doing a factory reset, and running it on it’s own dedicated, ORIGINAL, power supply. If that works, then you know that’s the problem.

These kinds of problems are very dependant on which other pedals you have on the same power supply. Unfortunately, it’s very difficult for the EHX engineers to foresee EVERY POSSIBLE combination of non-EHX pedals that you might use with your EHX pedals.
