I have a zoom 504II that I am playin my fender acoustic/electric through and I'm usin a session 400 amp. I like a good bassey sound for my acoustic, when I find a setting that has that bass sound, then when I strum across my big E and A strings I get a popin noise from my amp. I can cut my bass control back on my amp or guitar, and that helps, but then I don't have the bassey sound I like. am I tryin to run too much bass, or to much sensitivity that's causin this popin noise? any imput will be appreciated.

That's a bad connection, somewhere. The first place I'd check would be the molex connectors on the reverb chamber. (They give a LOT of problems!) Second place would be a dirty control. Third place would be the speaker itself. Bad voice-coils or tinsel-leads have been known to cause those type of problems. The last place I'd check would be a bad component or solder joint on the PWB. |

Thanks Donny, it's probly the reverb connectors, I've been havin problems with my reverb goin off 2/3 times a week. I've pulled the connectors off, and sprayed contact cleaner on them, and tightened the sleeves up a tad, but I don't think I tightened them where they fit at the top of the amp. did you mean dirty reverb control? thanks I'll try tightening the connectors at the top..

Terry...................I have had this problem off and on for several years. This is what I found. Upon loud notes(especially bass notes) that it is not the amp or guitar. what happens here is that the speaker cone physially bottomes out aginst the speaker frame/houseing and the poppin' noise is physical, a mechinical thing(eventho its sounds electrical). Some speakers are better than others. (I won't go into the speaker wars here). "Peavey" speakers (in my opinion) are the best at handling lows without bottoning out. Please try different speakers befor you dish the amps and guitars. Bill

I think Bill is on the right track. When you said the problem occurs when you add bass, it makes me think "speaker". If you can connect to another speaker,you may learn something. At the least, you will have eliminated the speaker as a problem. ....JD |

If you are plugging the Zoom unit directly into the front of the Session then the level (volume) of the Zoom send may be way too hot... ack off of it and turn the amp up more... maybe that will fix a few of your pops??Good luck !! |

Well, I'm sendin my zoom 504II back for a refund. I've concluded that it's just not made to play through a session 400rd. I tried all of the above suggestions, and can't get rid of that pop.
thanks for your help guys.

Nothing like resurecting a old topic, I had a similar problem on my session 500,It would distort or break up with certain low notes.Well I finally got brave enough to pull the magnet off the black widow and found that the foam dust screen thats right behind the wire screen had come apart (I guess with age and heat) and worked its way down between the circular groove in the magnet and the voice coil,it created a sticky goowy mess in there. My solution was to pull the magnet off and take rubbing alcohol and poured it into the groove of the magnet and let it soak for a couple of minutes, then turned the magnet upside down and dumped the excess out and use pieces of corragated cardboard to insert in the groove and clean the rest out. I then took a hair blow dryer to the magnet and dried it up good. then took a paper towel saturated with alcohol and carefully cleaned the goop off the voice coil,reassembled the magnet and she sings loud and clear even down in the low notes, I just wish I had done that a long time ago....maybe this will help someone somewhere down the road------------------

Check your speaker connections and your reverb connections.They do come loose from the vibration.

My wife has a Peavey TNT bass amp that makes a popping noise when she pushes it too hard. It will make the same noise with nothing plugged into it, when you hit the top of the amp, near the input jacks, with your hand. So I figure its the vibration from the speaker transferring to the amp chassis.I have removed, and resoldered the input jack, but that wasn't it. It must be a bad soldering joint, or trace on the circuit board, somewhere. Might be the same problem you are having. Les |

Terry, two more questions...Does the problem exist when you're not using the Zoom pedal? How are you setting the pre and master gains on the amp? |

Donny, I've already sent the pedal back for a refund. but to answer your questions
no, it don't do this without the pedal. I can turn the bass on the amp wide open and it still don't do it.and I have my volume set on about 2.5 to 3
on my amp.
