    I have a Dunlop cry baby that works fine with the battery but when you take the battery out and try to use it with a power supply it chokes as soon as you kick on the wah. The power supply is after market but its matches the pedals voltage and amphere requirements and i have even measured to make sure the voltage was accurate. I have plenty of experience trouble shooting this stuff but thought someone might have some ideas?

    Be careful to measure voltage while the wah is working. Measuring from the DC plug output of the power supply is not accurate as voltage decreases when consumption is applied. If you DC power supply measures at 9V, this voltage may lower when connected to the wah. Good luck!

    I had the same thing happen. I found that when I stepped on the pedal the little power plug was hitting the floor and
    interupting power flow to the unit.Check that out and see if that is the problem. :)
