Crazy Noise Problem In Some Venues

    Hey guys,

    My pedalboard (powered by a Voodoo Labs PP2+) works great in most venues, but some venues cause the most god awful noise to come from my Dr. Scientist Reverberator. Like a crazy hum that is louder than the effect.

    Now I've narrowed it down to the venue power and not, say another pedal in my signal chain because the RRR works fine in most venues with the same power hook ups.

    What are my options for eliminating this noise from popping up? Will something like the Monster Power or Furman surge protectors do the job? Or would the Lehle DC Filter be more my speed?

    FWIW, all of the other pedals on my board work great in all venues.

    We recently moved practice spaces and once we did we had crazy noise in all our amps, it comes and goes. I splurged on a Monster power conditioner that is supposed to be doing audio filtering - it changed pretty much nothing. I'm not an electrician, but I'm pretty sure it costs significantly more to truly get clean power, I've just learned to live with the noise and I've got everything in my effects chain gated, which helps. I don't usually have any issues at venues.
  3. Yeah, if your AC power is on the same circuit breaker as motors, fans, pumps, refrigerators, tube lighting, etc there really isn't much you can do other than learn to live with it or use a different (clean) breaker outlet.

    That's really a bummer. When this noise happens, it is significantly louder than my clean signal. Not really "live-able." I'm not really going for crystal clean / pure noise-less sound 100% of the time, but when this issue pops up it renders the pedal completely useless.

    Also, when the pedal is bypassed, the sound is gone. It is only present when the pedal is engaged (thankfully).
  5. Metal,
    I've used the Electro-Harmonix Hum Debugger to good effect with a 60 hz hum. If you hear this hum and it is the same frequency as your 440hz tuned 'B' note then the Hum Debugger will be a good friend ($120).
  6. Hmm, if the noise is intermittent, chances are you may be able to track down the noise source. See if you can find something like motors, fans, pumps, refrigerators, air conditioning, florescent lighting, electric fencing, and etc that turns on whenever you get the noise.

    The noise is intermittent from venue to venue, not song to song or during the gig. It just doesn't like some rooms, all or nothing. Maybe it's the lights in the room that are on the same circuit?

    Have you contacted the manufacturer? Sometimes they have knowledge of what causes these issues.

  9. Oh okay, then never mind. And yeah, dimmer packs can be nosey - lighting should be on separate AC breakers.

    TIP: At least invest in an AC outlet checker http://www.amazon.com/GE-50542-3-Wi...d=1397092464&sr=8-2&keywords=AC+outlet+tester and "always" check AC outlets before using them and if it if they're not wired correctly - don't use them (its not safe).
