Ok, so I've built Bean's MXR117 SAD 1024 version. It's up and running and sounds great except for the noise. While I can live with a little noise there is just too much to make this pedal usable. I'm out of my element on how to reduce it to where it's tolerable. I've tried it on a One Spot as well as my Voodoo Lab's PS and it is the exact same. It is not in a chain of pedals.
Noise wise, you hear the clock but if that was all I heard it is low enough to where I could get by and not sweat it too much. But the classic swooshing thing is just too much.
Any thoughts on how I might attack this problem would be helpful. I realize the SAD has more inherent noise however no way do I believe that all the old SAD chips were this noisy by 'design'. Now, this SAD chip could be in and of itself 'bad' but before I decide that I'd like to try a few things to bring it down some.
I have pics below to see if anyone spots anything out of whack. All the pots work however the one that jacks this pedal up is if I take the Regen past 75% there is an immediate squeal and I don't mean the kind that you go huh and it goes up when you keep turning. I mean the kind that will make you come out of your skin immediately.
Also of note the trimmer nearest the top and nearest the SAD chip is very scratchy while turning.
Thoughts from anyone?
