Problem with Power Plus 2 and Morley Bad Horsie 2

Post by Prudence » Mon Jul 16, 2018 11:44 pm

Hello!
I have a Voodoo Lab Power Plus 2 and I’m having trobles with my Morley Bad Horsie Wha pedal, connected to output 5. Theres a lot of hum and noise when its powered from the Power plus 2. Same thing when its powered from a regular 9V adapter, but works fine with a battery :roll:

How should I set the Voodoo Lab to get the Morley Wha to work properly? Or is at a known problem with Morley pedals?
The wha needs 9V and 300mA.

The actual current draw the Bad Horsie 2 is about 16mA (300mA is merely the capacity of its OEM power adapter) and it should work just fine, setup:

To power the Bad Horsie 2 Contour Wah with Pedal Power 2 Plus, use any output, DIP switch set normal with one of the all black (standard polarity) cables supplied.

Some devices (often times wah pedals, due to their inductors) are susceptible to coupling noise interference if placed in close proximity with a power supply, adapter/wall-wart, etc (due to the fields surrounding their power transformers). Many/most devices will be completely unaffected.

Perhaps this is the root cause?

Grab the wah and lift it away from the power supply, does the noise go away?

If so, generally, the best and most reasonable solution is to modify the physical placement of the offending pedal(s) and/or power supply.

Any better?

Ok, I'll try this. Thanks.
