    ...of all the pedals I have ever owned, why does THIS one pick up radio signals so much? Just curious, is there anything I can do to minimize this "effect" on the effect? :confused:


    Love this pedal, but man, the radio comes pretty loud sometimes. I have other germanium fuzzes that don't do this. I would have presumed it was the pickups, but I only hear the radio when activating this pedal (using a Fender twin btw, with Esquire, or Tele). is it just me?

    Does reducing the fuzz knob a touch get rid of the Radio noise?

    I have a Sunlion with the same NKT fuzz circuit, and I've never heard radio. But you will need radio interference to get the authentic Hendrix tone of the Isle of Wight performance :)

    I get the radio when I use the sunface and the beano together.

    I should add I do boost the signal with my Klon at the end of the signal chain, and that certainly adds volume to the radio signal, but the sunface is the only pedal in the chain that introduces it into the signal. sounds really trippy when i kick in the POG ...

    My Sunface just arrived yesterday, and it was a wtf? moment for me with a song playing through my amp!
    I'm curious to know how to stop it, but so far it doesn't bug me too badly.

    I had a recent funny moment with that when we realized allot of the Sun-dial pedals where having that problem at a Jam session with some buddies.

    I talked about this problem on a couple of boards and it seems that for some reason it only affects the pedals with the dial knob !

    it wasn't that big an issue that I thought of bugging Mike about, especially since I have an original NKT Fuzz Face that acts at times like a real FM receptor, ( imagine us having blues jam and as the song fades out we hear : I drove allll nightttttt ! )

    It's in a sense the nature of the beast when dealing with vintage circuit boards and electronics ... but heck do these Sunfaces sound good !

    My suggestion, try one without the sundial knob !

    I don't recall my NKT-275 (When I owned one) to pick up the radio. I have had my Rangemaster pick it up once or twice butr it was pretty low in volume. I thought I had read somewhere that there's a component you can add or a device of some sort that will stop it - but I can't remember if it was a BS article or just another thread that had someone with the same problem. It was years ago.

    I had the same issue and analogmike said they will do that. It depends on the amount of radio signal in your area If I remember correctly. I think he mentioned way to stop it but I can't remember what it was. Send him an email. He'll help you out.

    right on, i'll shoot Mike an email. No doubt, great guy, great pedals... and the radio thing does make for some funny moments in between songs : )

    never had radio frequencies with it....
    though it sounds like it might be fun in small doses

    foil hat will do it!!!!

    One easy thing you can try is to turn the white clean trimpot down a hair.

    Any fuzzface can and will get RF interference depending on your location. I was at Lenny Kravitz's old house in NYC and they got RF I/F so bad they used metal doors with foil seals. But they still could not solve it completely.


    Radio Frequency Interference (RF IF) is a tough one, most
    gain pedals like Fuzzes and even some wahs have a lot of RF problems.
    Since we cannot duplicate the problem here (it has no noise here)
    it's not something we can fix at our shop.
    Gain is amplifying the RF from the air like a radio, it is tuned
    to the local station. Sometimes shortening wires or adding ferrite beads
    will help but since we dont have the problem here we would only
    be guessing. If you have a good tech he can try shortening the internal
    wires one by one and test to see if that helps, or he can try
    adding more and more ferrite beads and see if that stops the noise.
    Also you can try to add a small capacitor on the input of the board
    or the input jack to ground, that often kills the noise. Try something
    small like 100pF then go bigger up to .01uF if needed. We often
    put a small cap right on the switch from the TO BOARD wire connection
    (gets connected to input jack when ON) to the GROUND connection.

    Also dirty jacks can cause RF interference, try cleaning them
    with a swab and some contact cleaner.
    A customer wrote :
    "One thing I did was to uncoil all the power leads in the back of the rack. I had them coiled up pretty tight and then cable tied. This immediately helped, but I wasn't completely satisfied.
    At this point, I noticed that to make the radio signal be it's worst, touching the audio plugs on the back of the power amp (Metal sleeves) would do it.
    So next I soldered some 4.7pf capacitors across the DC connectors on my pedals. "

    another customer with RF problems with a sunface wrote:
    "Thanks for the note, Mike. After applying an, ahem, no-to-low-tech technique it seems that the RF IF problem is gone. Get this: after reading your reply I got to fiddling with the guitar cables in the chain, which includes a Framptone Amp Switcher in front of two amps. Anyway, I just swung the guitar-out cable from the Strat around from the front and behind my body and presto/change-o, the RF IF disappeared. No contact cleaner, no screwdriver, no solder. No BS."

    Here is another who found a simple fix for RF noise on a sunface:
    "Thanks for your detailed response to my question. I was able to solve
    the problem. I got a ferrite clamp from Radio Shack and tried clipping it onto my
    guitar cable. It eliminated some of the RF noise, but not all of it.
    I also noticed some loss of clarity from my guitar signal so I decided
    to ditch the ferrite and try adjusting the internal trim pot.
    I set my guitar volume to the most offending spot and adjusted the
    trimmer until the noise went away. I only ended up turning it down a
    bit. I would guess it's somewhere around 85%. Now I can use my
    guitar's volume knob to get that sweet spot w/o the RF interference."
    Hope that helps, good luck!

    I get very little RF on my Sunface (only when the plexi and=SF are allon 10) but have the new dunlop FF and it get Tons of RF when a volume knob is at 0...would the cap from ground to input work their mike?

    I have never had any rf, but I turned my trimpot ( inside pedal ) down from the get go so that may be it.

    You know, Mike's always so quick to throw in here and there & help us out... thank you Mike! A strong indicator of how great of a buisiness guy he is and how important his craft is to him. Top notch.

    Thanks for the info Mike, I'll definitely look at my cables, and adjust the trim pot.

    BTW, the sunface is just blowing away my other fuzz pedals for so many applications.. AND, that it takes up so little space on the board is a nice bonus!

    Mike, anyone ever tell you how much of a class act you are ? I mean I've had nightmare situations over the years with Fulltone, Klon etc ... when stuff broke down, you are a credit to this industry and I can't tell you how much I worship your peppermint fuzz

    I get a lot of RFI at my studio, and some from my old wah. I got a Monster Power Pro 2500 power conditioner, solved it completely. Not really convenient for a rig without a rack, but it may be something to look into.

    We use a Monster Pro 2000 power unit at the shop for our demo amps and power supplies... could be why we don't see the noise problems here????
