There’s this high pitched swirly hiss that happens when you turn the effect on and also it’s there during the playing.
Do you have the LFO switch on and exp pedal (hooked up?) Mine (it’s an “M”, not the “B”) will do that if I attenuate the pedal then pin it to the toe position. I back it off a bit and it’s barely noticeable.
What are the exact knob positions and what type of signal do you have plugged into it? I’d like to model it on my Midi Murf to see how it might differ.

Drive: at 11 o’clock
Pattern: 3
Output: at 3 o’clock
Envelope: 6
Mix: 10
Rate: 8,5
All knobs are on the top.
So it’s a simple tremolo effect what comes out.
If I lift the 1,8K knob down then most of this high pitched sizzle is gone.
The signal is from my bass guitar.
It can be also the problem of my instrument or wires.
I will try to send another signal in and let you know if this problem is still occuring.
I am afraid that the reason why my moogerfooger isn’t working is that once I accidentally plugged my boss adapter into moogerfooger.
Is it possible that the false adapter with other power-settings can spoil an effect pedal?
Check the polarity and voltage. If the Boss pedal is a higher voltage, different polarity, or both, you may have stressed or damaged a component.
Yes there is difference in polarity.
Is there possibility to fix my moogerfooger?
Sorry, man! Check with Amos, you might get lucky and only need to replace a diode. Maybe…
Sorry but what is Amos? I am really rookie on this stuff.
I apologize. Amos Gaynes (sp?) is one of Moog’s people who frequents this forum. We usually just bounce things off of him before going to tech. support. His user id is AMOS. However, since you’re new you would probably do better to call Moog Music tech. support and ask them. Their number should be in your information packet you received with the 'fooger. It’s also listed on the web site. It’s not toll free, so you may want to send them an email instead.
Tell the tech. support person what happened, and the symptoms you’re experiencing. If you’re still under warranty, they might cover it, however be prepared to pay in case they don’t. If they won’t cover it, then if you’re handy with a soldering iron and know what you’re doing, the tech support guy might be able to tell you what component(s) will likely need to be replaced, enabling you to do the repair yourself. (Often a sacrificial component is designed into the circuit for this kind of mishap.)
However, if you don’t have the experience or correct equipment needed for working on static sensitive circuits, then bite the bullet and pay the man to get it fixed right. Otherwise, you’ll probably end up making it much worse!
I hope this helps. Good luck and keep us posted.

I had the exact same experience with my bass murf when i got it. I bought it used, so I thought that perhaps something was wrong with it.
If I remember correctly (it was several years ago), I sent it in to Moog, and got it back seemingly in the same condition, with a clean bill of health. In other words, they could neither replicate nor find a problem.
I haven’t gone back to my murf for quite some time, but I will now. I’d like to check if playing my bass in passive mode or changing my pickup selector has any bearing on the issue. Also, I have a mooger lowpass; I’ll put it through and see if I still hear the high-frequency whine with that.
More to follow…
ok…did a little searching here…it seems this issue is not isolated. lots of folks report a high-frequency whine / noise with their bass murfs (and other moogers for that matter).
so here’s a new question - do we just have to live with this high-pitched whine and find our own way of “fixing” it?
What are the settings under which this occurs?
I have both the Murf, and the midi Murf. The only noise I can hear is when I turn up the gains way too high, with no input signal, I can hear the patterns cycling as I alter the envelope settings. This happens on both Murfs, and it’s consistent between the two. Other than that, if the gain levels are appropriate for the signal out of my Voyager, there are no extraneous sounds coming from either Murf.
It may be a signal to noise ratio thing. Is your bass putting out a strong enough signal to drive the Murf? If your bass uses active pickups, does the battery need replacing?
Just some random thoughts. Good luck!
