Guitar makes popping,cracking sounds when plugged into amp.

What make a guitar do this? I'm thinking a loose wire in the input jack,or a loose wire in pickup. I have a Yamaha APX-5NA classical A/E. It has a killer sound when I plug into my little bass amp. It's not the amp,because I play my Tele and bass thru it all the time. I am right about a loose wire? What else do you think it could be?

It could be a loose wire, it could be a shorted wire, it could be a completely disconnected wire. I don't know what kind of pickup you've got in there, but what I usually do is get inside the guitar and check everything out, making sure that everything that looks like it should be connected is. If its not, I usually bust out the soldering iron, or if its minor, electrical tape should do the trick.

Good luck!

Thanks. I'll take it to the guitar store and let them fix it. I can't even put strings on a classical,much less do my own work. I'd ruin it for sure. Maybe I'll check out the jack,I could probably fix that,if that is the problem.

Turn on your amp and plug in the cable...Wiggle the cable when it's not plugged in and see if any crackle occurs...if none, then wiggle the cable when plugged into the guitar...if you get a crackle, it's most likely a bad solder joint or a very slightly bent terminal on the "hot" lug (the part that comes in contact w/ the cable's tip) that's not making good contact.

 

Either is a very easy fix...either reheat all solder joints on the input jack (just to be on the safe side), or bend the hot lug inward to make better contact.

 

Feel free to send the $25 or so I just saved you to a good charity...I like NORML ;)

Moisture in your attenuator pots can bind to dirt and dust that gets in through your jack and reek havoc on your sound. I found something you may want to check out. It is a new product that addresses that very problem. It's on KickStarter. I will put a link here for you to check it out. It's called the Jack Guardian. Here's the link http://kck.st/1zaxG2K

You're right, of course. I was out of line there.

 

tommyc, thanks for the tip. KATMAN probably got it sorted out soon after he posted but your reply is no less valid now than it would have been 9 years ago when he first asked for help.

I regularly use some contact cleaner on a Qtip to clean surfaces inside jack, besides wipe downs on both ends of cables. I live in Thailand and seems everything that can get gunked up and/or corroded does. Could try a different cable..... Oh, also wipe off contacts for battery if has a preamp.

Oh, welleth, you'll haveth that. $22K? Hungry varmint, too.

 

There was a similar campaign for some new fangled finger picks that I thought were a great idea. But, I never saw them commercially available so I guess someone didn't get enough financing together (for the new Beemer, that is).
