brand new pedal power 2+ makes loud hum

Post by magilla38 » Wed Jul 11, 2018 9:21 pm

i recently purchased a 2+ and i seem to be having a problem. i hooked up my board and turned on the amp and it immediately makes a loud hum. i started plugging things in one by one and checking. i can get 5 pedals hooked up but if i put a 6th in i get the hum.

setup works perfectly fine with my one spot daisy chain

tc polytune
boss OC-3
boss ODB-3
EHX big muff
EQD rainbow machine
EQD avalanche run( in postion 6 with normal switched up)
EHX 360 looper

tried with different amps and different cables etc and still have issues. i'm sure i'm missing something but i don't know what

My first guess would be the issue is power to your Avalanche Run. It should be setup:

To power your Avalanche Run with Pedal Power 2 Plus use a Current Doubler Adapter, part# PPAP in outputs 5 and 6, DIP switches set normal with one of the all black (standard polarity) cables supplied.


Any better?

yeah that fixed it. didn’t realize the current draw on the avalanche run was that high. also had a bad cable that was causing most of the confusion. thanks.
