Hey everyone -

I'm puzzled with this pedal. I have built several of them. A GGG version, and 2 vero versions.
The one thing all 3 seem to have in common; the work really, really well if I use a battery.
What I mean is, they are quiet. But as soon as I put the wallwart to them, noisy as hell!

I mean, I tried swapping wallwarts from my standard ISPOT (I happen to like that one a good bit).
In fact, I use the ISPOT when I test all the pedals I build and the only pedals that produce this noise;
The Orange Squeezers - so this rules out the walwarts that I have or dirty power.

Perhaps I'm missing something but for the life of me, I can't figure out why these 3 builds all result in the same noise when not using a battery (mind you, that the GGG and the vero builds don't use some of the same parts - so I think that rules out making the same mistakes 3 times).

So in closing, I guess I'm asking if this is common for this pedal and if so, what have others done to stop this line noise..

Cheers
Chris
