Ibanez NB-10 Noise Buster

Original info:
Unlike conventional noise gates, the IBANEZ NB 10 Noise Buster is capable of cutting out noise not only while there is no signal flow, but during actual playing as well, thus providing far more effective noise reduction. A FREQUENCY control lets the musician eliminate noise components without impairing the envelope or sustain of the original sound. With the NB10, players are liberated from the adverse influence of stage lighting or single coil pick-ups on their music, and high gain distortion effects can be used without having to worry about noise.

  1. Really impressive work making this 1590B friendly! Thanks Alex! I'm gonna give this one a build once I get the IC

  2. Thanks Alex - this is JUST in time for me. I was looking for a good noise gate and this looks like a great one. I like that it also has an RF filter.

  6. You can get the LM1894N from one U.S. vendor on eBay for $8.

    This is an interesting circuit and I'd love to hear if anyone builds it.

    3. I got three of them for $10. I guess I have two extra. I just built this but on first test it did not work. I need to go over it. One thing I don't understand is it does not have a threshold control (for setting where the gate kicks in) - it just has the frequency control. Is the threshold automatic, or doesn't it also work like a regular noise gate (the manual says that it does, but I am not sure how)

  7. Call this verified. I have some very high gain pedals that make an obvious background noise such as my BSIAB. This thing really does the job eliminating almost completely. This will now definitely be on the everexpanding pedal board.

    1. I'm assembling this as I wait on some parts and found the link next to the 100p cap near the top right is in two different spots in the two layouts. Otherwise looks good.

    2. Thanks!
      That was fixed on the day you've mentioned it but I forgot to write it.

  8. Alex - are those small red caps along the top 100n or 100p? (they actually look like 100u)

    1. Nevermind - when I zoom in I see they are 100p

  12. Hey Larry, try re-flowing your solder points. Mine wasn't producing any sound either, so I re-flowed and now it's working beautifully.

    1. thanks for reply, I will try this weekend, I will report back.

    2. All fixed. Only thing that I have noticed that pot does not silence all the noise. I have Boss NS-2 and it is way more efficient. Really a big disappointment with this pedal if it is like it should be. Maybe I have done something wrong.

  13. I finished mine this weekend. It seems to work well. It seems to really tone suck the highs when the pot is turned up. I guess its the nature of the beast. Does anyone know if we could mod it to too take out less highs ?
