today my murf was acting funny. We had my friends Rhodes plugged into it, and at first it sounded like a bit of hiss coming from somewhere. then we noticed that the knobs seemed to stop working. we thought maybe a bad cable but they were all fine. then we noticed a weird "delay" type of sound and almost like a very faint tv signal coming through. i unplugged everything and then it was okay again but would start up again.

i'm wondering if maybe it's the power supply or maybe because it was in fairly close proximity to an RME firepod which we were using to record and a computer monitor.

so anyone else here notice weird noises and or knobs not doing anything? After we moved the foogers away from the firepod and monitor it seemed to go away gradually. maybe a weird power surge? or interference?

I don't own a murf, but i know that with wah-wah pedals, if you plug them in backwards they pick up stray signals in the air...maybe the same thing happened with your murf...

i've picked up a local mexican station on more than one occasion with my vox wah (even when plugged in correctly). used it as a textural seasoning, which was fun, but aggravating when you don't really want it there.

Once I mistakenly used a 12 volt adapter instead of the normal one, and it wouldn't work correctly - I think the knobs stopped working, but it was four years ago so i don't remember the specifics. Are you sure you're using the right adapter? I finally had my friend put labels on all the adapters so that I could tell them apart! (The 12 volt adapter was for the Budda Phat Bass pedal - I think I even have an 18 volt adapter!)

i was only using foogers. it may have been possible that i got one of the adapters mixed up. but they must all be fairly similar in terms of power. I was using 101, 102, 104sd, 105, and cp-251. all of these foogers are 9v i think. the murf was sitting on a bench right beside the rme firepod, and there was also a computer monitor fairly close as well. THis has never happened before. maybe a power spike? i was going into a power bar that didn't have surge protection.

i played the murf again today and it seemed fine. it just got me worried because theses things are so expensive and i love them to death.

following is from the murf manual:

"Note the MuRF uses a different power supply than some other Moogerfooger effect modules, which are only rated at 200mA. Using a 200mA power supply may result in hum, distortion, and other less than desirable audio artifacts. Make sure to use the proper power supply."

it's more likely this was your culprit. you might want to label the MuRF power supply to avoid any future mixups...i also remember reading that using anything higher than a 9v adapter may cause permanent damage to the unit- all the more reason to be careful & label those adapters.
