More hiss from external powered wah? Answered
I put together a gig box with power, and everything is fine.only problem is I have a George Dennis wah at the beginning of the chain, with a battery it is just fine. It has a power jack mini plug ts connector. Tip is positive and ring is ground. I am a technician , so I made a cord from the gig box power supply, reversed the tip and ring, because the ring is positive with guitar toys, it works but now I have a lot of hiss, more than normal, I use a nova drive of distortion and have a noise gate. When I unplug the power from the wah the hiss normalizes.
if I use an external power supply for the wah it is ok.
Used a meter and the power is correct 9.3 volts dc.
Not sure what to make of this?
