Annoying Feedback Noise

Re: Annoying Feedback Noise

Hi, Kevin - can't help with the noise, but the little tag on the pot is a positioning lug, for where there is a corresponding hole on the guitar/device. You can bend it flat or clip it off, no problem. That'll let the pot casing sit flush with the cavity.

Re: Annoying Feedback Noise

As a test you could always connect the pickups directly to the jack so that you are bypassing everything in between. This way you should hear if there are any problems with the pickups themselves.

Also, it doesn't look like you have any shielding (wires nor cavity). This will also play a large roll in what you are hearing.

The only thing I see that might be a candidate for a problem (I can't really see what's going on with the green and bare wires for the pickups) but at least one pickup has it's green/bare wires quite close across the volume positive lug, which once it's all put back together and closed up might push the ground into the positive lug. Can't really see though.

Re: Annoying Feedback Noise

Does your output socket have a little extra wire sticking out? Sounds daft - and I am also an amateur - but could it be touching the jack when you plug it in?


Edit: I was mistaken; I was viewing at these on my tablet. Forget that comment.

Well you have a groundwire problem somewhere!

Re: Annoying Feedback Noise

Yeah, that's grounding hum, not feedback. There is a ground wire either missing or not soldered correctly.

Re: Annoying Feedback Noise

I'll try that. The most aggravating noise is gone. I'm getting more power out of the pickups now. I still have a hum but I can live with that. I'll try the direct pickup to jack connection. I started using the shielded wires, but I had limited room. I am using shielded from the tremolo to volume pot. I've read about shielding tape or paint. I may try that later on. Thanks.

Re: Annoying Feedback Noise

Let me go through my grounds just to make sure I'm not missing something. Tremelo to volume, volume to tone, jack to volume, switch to volume, both green and bare to volume, and cap to tone. Is there something else? Thanks.

Re: Annoying Feedback Noise

I noticed that with some of the pictures it appears that there are wires touching, but none or touching. I also checked the jack to make sure that the wires were clear of the cable input. I have everything clear. Thanks.

Re: Annoying Feedback Noise

It isn't near any of the lugs. The angle of the photos gives the appearance of things being close. You guys are awesome. Someone is going to figure it out. I do have a question? There is one thing that I'm not sure about. Do I have the main pickup cables running too far into the control cavity? I did this to minimize the exposure of the thin wires. I thought it would be more advantageous to use as much of the main insulation as possible. I even taped some of the wires to thicken the protection. I'm thinking maybe there is too much clutter around the volume pot although that none are remotely near the lugs. I'm thinking that it wouldn't matter if portions of the ground wires are resting on the Volume pot. Would it be alright to push the pickup cables further up the guide holes and expose more of the thinner green, bare, and black wires to lessen the clutter.

I don't like how the tone pot is resting against the cavity. I don't think this would matter though, considering the wood is ground. Maybe I'm making too much of this. Is it normal for passive pickups to have some hum? I listen to guys playing on youtube with the same pickups and they don't have hum. Unless, I just don't see them resting their hand or finger on something metal.

Re: Annoying Feedback Noise

If touching something metal reduces a hum then I think you are grounding the guitar.

Not ideal.

Re: Annoying Feedback Noise

Ok. I took my time and spent 4 hours last night rewiring the whole thing. It's less congestive and look pretty good. I hooked it up a few minutes ago and it still has that transistor radio, whistling type of sound. It's not very loud but it's there. The more I turn up the amp, the louder it is. I forgot to turn my standby off on the amp and unplugged the cord. The fascinating thing is that the same exact noise is there when the cord isn't in the jack. Could it be the amp causing this noise? I don't understand why my other guitar doesn't do this. It has active pickups and someone posted on here earlier that these pickups are configured differently as far as grounding.

These cords are new Monster cables. The amp, a Marshall DSL-40C tube amp, is about 16 months old. What the heck is going on? I'm ready to have a tech look at the guitar. It's a shame, because I changed everything on this guitar and I want to complete the project myself. I don't want to take it to a tech and spend money to have someone fix it, to find out that it's the amp.

I just used several other cords and the same thing. I also done a little experiment on the guitar. If I turn the tone all the way down while the volume is turned all the way up, the noise disappeared. I played around with the volume while the tone was all the way down and the noise would reappear at various turns. The noise stays constant while the tone is turned up no matter how I turned the volume.

Is there a particular way that the spacers, washers, and nuts on the pots and switch have to be for grounding? I place the rough looking spacer on the inside followed by a spacer and nut on the outside.

Re: Annoying Feedback Noise

I know somebody out there can help me. I'm begging for someone to figure out what is wrong. Please help me. I'm getting tired off trying to rewire the guitar. Just look at my last post and tell me what is wrong. Somebody out there has experienced the same problem. I really do appreciate all the help I've received so far. I'm not saying this lightly. I'm absolutely thankful for everyone. This site isn't just a forum, but a support site within the guitar community. I can take negative criticism. If you see something that I'm doing wrong, please tell me. Thanks again.
