This is weird... I had built an Abider (Dude) previously and liked it. Recently I rebuilt my pedalboard and used a One Spot Pro CS6 which is great because it is low profile, fits under my Pedaltrain Nano with few mods and has been whisper quiet with all of my pedals - until now! Seriously, compared to my previous power supplies - Voodoo Labs ISO5, various others... it's been very quiet.
So I was really surprised when I plugged my Abider in and it hummed fairly loudly. I assumed there was something wrong with the pedal, so pulled various bits off to see what was wrong. In the end I just built another one (with a few diode mods) as I had the board. Plugged it in and there's that hum again. Tried a different power outlet - still hums. Tried a new DC cable - still hums. Used an old Ibanez power supply for just that pedal - hum goes away. None of my other pedals do this. I have three other pedals inline - a Korg tuner, my home-made Tim, and a Source Audio Collider. I often put a new pedal in front of the pedalboard to test it and out of dozens the Abider is the only one I've had an issue with. And now it's with two of the same pedal - I didn't reuse any parts either. And it still hums even if I go guitar > Abider > amp, no other pedals inline.
Any ideas why this is happening? Does my Abider just not get on with this power supply?
