If I touch the pedal or the strings and the hum goes down in volume, but does not completely go away. If I turn up the gain and master, obviously it gets worse. If I turn on the overdrive pedal it gets seriously bad, that I cant drown the hum/buzz with my playing. The amps dont make any noise, connected to the same outlet as the distortion pedal. I even connected it to a portable battery operated amp and the result was the same. As soon as I connect the distortion pedal, it starts making noise. I have used all different types of power supply units for the pedal from Zoom ac adaptor, One Spot, Strymon, generic POS, etc etc. I cant get rid of this stupid loud hum. Is there a remedy for this? What am I doing wrong? Thanks for all information and advice in advance. Forgot to write, no other pedal is attached except for this overdrive pedal.
