Trem spring damping

Hi guys!

I play an RG7620 and get this irritating 'wom' feedback sometimes and I have a feeling that it's coming from the springs under the trem. It's taken me ages to come to this conclusion as i'm normally on stage when i notice it and i use pretty hefty noise gates that eliminate it most of the time.

Anyone got any good ideas for damping them without ****ing the beast up? My first thought was some kind of cloth to put between the springs and the backplate but i was wondering if it might get caught in the spring and knock my tuning out. I'm gonna try it anyway, but if you guys have any better ideas, i'm all ears!

cheers,
james.

I fold a piece of paper towel and put it between the springs and the guitar body (because I don't have the spring cavity cover plate on). Works for me.

Cheers. Does having no cavity plate do anything? I've seen a few people without them. I always assumed it was cos they lost the screws. I think Mr Vai may be one of those people.

I wrap electrical tape around each one individually. That silences them completely. Another suggestion is to thread cotton inside the spring. I would think that could work loose or get caught in the coils, but someone here said that's what Vai does. If you do a forum search you might find it.

I had the same problem with a couple of my guitars. I placed some foam rubber under the strings. Works great.

Just cut some strips from washing up sponge - 6mmx6mmx40mm (1/4"x1/4"x1.5") and use some thread to get them inside the springs.
The last time you are ever going to hear spring noise and it looks great from the outside.
I'll take a photo and post it tonight.
Here you go - pics 3 to 6 show how to get rid of unwanted spring noise without stuffing loo paper in your guitar.

Mr Nordegg, take notice.

those are all great methods to stop the trem springs from ringing -- i use a thin strip of foam between the body and the springs -- but i've never heard of springs causing feedback like you describe. vibrating springs usually give a faint echo like reverb when you suddenly stop playing and mute the strings. feedback comes from the pickups.

the "wom" sounding feedback you describe, a low moan rather than a high-pitched squeal, usually comes from the pickups vibrating in their mountings. it can happen when the strings are muted [just like ringing springs]. to see for sure, get your axe feeding back and then grab the pickup really tightly between your thumb and finger. if it's vibrating in the mounting, you should feel the vibrations and your grip should choke off the feedback.

this kind of feedback can be really tough to fix -- since it's not loose windings vibrating inside the pickup, repotting the pickup won't help. on Les Paul type humbuckers mounted on rings, i will stuff a huge block of foam underneath the pickup in the cavity. with the 7620 direct mount, you can't do that. you could try bigger mounting screws and more strips of mounting foam underneath the pickups.

a first check would be to make sure the existing screws are clamped down tight. if they aren't because you've got the pickup set high, close to the strings, consider adding more mounting foam or thicker foam, so you can have the pickup high yet still crank down on the screws.

Thanks, everyone! Damping the springs seems to have sorted out my problem at low volumes, but i guess i'll have to wait until i next crank it up to see if it's fully sorted. It's sounding hopeful though!

vai himself uses folded kleenex/tissue paper placed between the cover and the springs.
