Floyd Rose issues.

I just got one of my guitars back up and working. It was a gift from a friend several years ago. Its a Kramer (I know like 30 years old) and I'm having issues with my Floyd rose. I have the bridge set up perfectly straight. everything in tune and using the whammy bar works fine so I know its not issues of the alignment. The issue is that my guitar is making a ridiculous screatching sound when I have my amp loud using distortion. I know its not my half stack because I use my Schecter Diamond Series on it all the time and I don't get the sound. This is happening on many different amps also.

I looked up what could be the issue and I've heard that putting foam or a wood block underneath the springs could help because it could be due to the springs but, I put 2 Pieces of foam under it and I still have this annoying feedback sound. My guitar has old pickups in it but I wanna make sure its nothing else before i try getting new pickups. I do not know what types of pickups i have on it now other than one says a quad rail and the other two say dual rails. I'm assuiming thats what it is. I know i've typed a lot but I'm hoping someone can help. Thanks.

Hm... strang. Sorry, can't really help you here.

I'll recommend having a pro guitar tech set up the guitar and check if theirs anything wrong with the pickups or maybe some wires/pots that need to be replaced.

Ask around for someone who has a good reputation.

Possibly a bad cable (the dimebucker is a hot pickup) or a loose input jack on the guitar. I know on my DOF the jack got loose a lot so I put teflon tape on the threads.

This is a stab in the dark, but along the lines of what elklandercc said, have you tried a different cable? How close are you to the amp? How about trying plugging in straight into your amp with no pedals? There's been times I've been plugged in with my pedals on, then go turn my amp on with guitar in hand and practically blow my eardrums, depending on which guitar I'm using. Oh, I just notice you said, "amp loud using distortion"- have you tried turning the gain and or level down? I know on my distortion box, depending on the guitar, if I have the gain up too much, I get a deafening screech.

How about plugging straight in clean, and see what happens? Maybe a gear guru like Lordathestrings can add some insight if he sees your post. Good luck.

I suggst trying a different cable, if that's not it then you could have a loose connection coming from your pickups or the changer switch (have one on my Prestige at the moment and it gives a scratching noise). Kramers are nice guitars so if it could be worth having a luthier look at it and give it a full setup.

Well, It occasionally stops. I play kinda far away from my amp.. and i'm only getting crazy feedback when I turn my petal on. But when i put it on the same settings with my other guitars it works fine.. I'm not completely sure what the issue is. As of now I'm trying to get a hold of a good Guitar Tech that is certified by lots of major companies and see what he can do about it.. I mean once I exercised it with the whammy bar it stopped but eventually picked it back up. I really wanna say it has something to do with the springs.

Maybe i have it set up in correctly. But hopefully he can figure out the answer.

In my very uninformed opinion, I think it's some type of circuitry problem. Have you tried plugging in clean, with no pedals? Different guitars respond differently on the exact same setup. I think you should try a process of elimination- try a brand new, quality cable, eliminate the pedals, see what happens then. Have anyone who can look under the hood and see if your pickups are wired properly?

I've always been lazy when it came to the maintenance of my guitars, but with a growing guitar collection, I'm slowly learning; recently, on one of my Strats, I plugged in, no sound, nothing. I removed the output jack and saw a wire loose. I googled for schematics just to be sure, and for a total of about $15, I got a cheap soldering iron and solder, and soldered the wire back on, and I was back in business.

Just hate to see you spend money on a tech when the problem is "obvious".

Feedback happens when the sound from the amp causes part of your guitar to vibrate. The pickups produce a signal for the amp when the strings move relative to the pickups. Whether that movement is due to your picking, or due to the sound from your speaker doesn't matter.

You can try putting some soft foam under the pups to keep them from flapping in the breeze, but you may simply have to be more careful about how you position the guitar relative to the speaker.

You might also roll back the gain a bit, but that's not as much fun. Feedback can be a useful effect, if you can control it. Infinite sustain! Try working with it.

Considering the guitar has some age on it, I'd guess the pickups have become microphonic.

Like ^^^^ HDJ said, plus; check your pick-up height, you can get problems if the pick-ups are too close to the strings.
