Zoom B3 Noise

    I have a problem with my Zoom B3. It does not want to play well with the other effects on my pedal-board. I get a high pitched whine and clicking noises but only when connected with other effects. It is very quiet when used on it's own and all of the rest of my effects are dead quiet when used with each other.

    I have a Joyo PS-2 so I should have clean power to the unit. I'd like to keep it in my pedal-board for the versatility. About the only way I can think to make this work would be to use a splitter which I really don't want to have to do.

    Has any one else encountered this? If so what did you do to solve it. Is it solvable?

    Where in the chain are you putting it?
    Mine doesn't really like having too many pedals before it sometimes, but it has pretty much replaced my board apart from a Ibanez PhatHed and MXR M80 DI.

    one solution is to make sure that pedal is on active vs passive. On the back of the B3, there is a button that is active and passive. The manual states that the B3 needs to be on active if you place pedals in front of it.

    Hope this helps!

    Troubleshooting is a process of elimination. Change one, and only one, variable at a time until you find the cause.

    1) Try using the Zoom supplied power supply. The Joyo isn't likely a truly isolated power supply like the Voodoo Power units.
    2) Make sure you don't have the Zoom plugged into USB. That's notorious for causing audio noise such as clicks and stuff.

    Yes I have had it plugged in at the end of the chain. I'll try the active switch 1st and try putting it at the front of the chain to see if that makes a difference.

    Yes I've noticed the USB noise as well. This noise is pretty much similar to the USB noise but I get it with the B3 unplugged from the USB.

    Thanks for the responses, I'll post back if I find a solution that works.

    Tried moving it around the chain. middle front. I was actually quieter at the end of the chain and noisiest at the front. I don't know why all of my effects work well with each other except for the B3. I guss the next thing is perhaps to try the B3 with other effects one at a time and see if it's possible to isolate which effect(s) are incompatible. This is really kind of a big disapointment.

    I hope I didn't miss this, but a lot of times when adding these devices the type \ quality, capacitance of the cable is often overlooked. Just a suggestion.

    Although not a practical fix,but for the sake of troubleshooting;try plugging in everything as you did originally.Now disconnect B3 power supply & try battery power.

    Some of the amp sims can add noise, especially depending on the comp.

    I was just struggling to figure this out as well. I'm getting the same high-pitched sound when I'm using my B3 as well. I have it set up behind a compressor and in front of my BBE Sonic Stomp with USB unplugged. It doesn't matter if the compressor or sonic stomp are on/off, the sound continues. Curious to know if you've figured anything out that fixes it (other than isolating it from all other effects and using it as a stand-alone).
  11. There is a faint processor whine from the Zoom units that can become quite annoying depending on placement and power supply especially when playing thru an speaker with a high tweeter or powered cab. i have been able to de-emphasize that sound by using the oem power supply and finding the right placement.
