As a new monthly feature I thought it'd be great to get Chris May (the master luthier behind 'Overwater Basses') down to SBL towers and share some of his knowledge with the SBL community...
In this brand new session Chris discussed "Shielding and Noise" talking specifically about why it happens - and how you can take some simple steps to get rid of it.
And trust me... if you're doing a lot of studio work, work in theatres, or have aspirations of doing these types of gigs - noisy basses can be a real headache, and knowing how to fix it is going to be priceless in so many situations.
As always, see you in the shed...
Scott :)

this is literally a blessing from the youtube algorithm i've been trying to solve the knobs turning crackling sound for soooo long I've even completely switched out all electronics from scratch...

Hey Scott. Great piece with Chris May. I've been a part time luthier here in north Idaho and everything that Chris talked about with shielding I learned from Mike Lull when we lived in Washington state. I teach the kinds of things Chris elaborated on and every bass or guitar I've ever modified or built from scratch is dead quiet using those techniques. By the way: you can find the nickel based lacquer on Amazon here in the states (perhaps in England and Europe as well) under the brand name of Super Shield by MG Chemicals. It does the job! Thanks again for getting this information out to the bass playing community, and special thanks to Chris May for his time.

Man, so I came back to this video after I had a nightmare of a morning with live streaming. Bass was making basically old radio sounds, thought it was the pots for months. Turns out it needed shielding real bad! Thanks for these, Scott!

I had an active bass that sounded mega but couldn’t record with it due to high frequency white noise. Just recently I pulled it out and realised the pickups were to low hence having to turn the level up so high I got noise, have to strip the bass because the pickups just won’t move, I hope it works, I love the bass.

Great Video, One of the things I would have love have Chris get into epoxy potting and the possible pros and cons.I work as an aircraft mechanic or in your country I would be called an engineer. We deal with all kinds of shielding issues that cause all sorts of odd noises in the Com system. So everything I herd Chris say was bang on. I really like the coper gauze and I had no idea that the entire pickup was encased in it, I thought it was just the back side. I just wish I could afford one of his basses!!! Scott as a life member of you academy I appreciate all you do, thanks!

I met John East himself at his house! Super nice guy, even going as far to fit my U-Retro preamp into my bass for me since my dad and I had come a long way and we were complete bass newbies at the time! Haha! Great video as usual, looking forward to the next instalments. :)

Love the part on shielding! I have gone as far as putting the vintage shield stripe from under the bridge across the body and down into the pickup cavity - I think it looks cool, but it’s a fail safe too. All my basses are quiet until I hit the SansAmp or the mig muff; at that point I cannot control what melts or explodes.

This video may have just saved my life. I've been asked to play bass on a production of Disco Inferno for a local musical theatre group and I was planning using my jass bass. Unfortunately its a really noisy blighter and like I said this has helped a lot. I'm gonna try to install some shielding and see what happens. I may have to use the p bass if I don't have any luck 🤔. Thank you for doing these types of videos, fantastic 😀

@RandyLott 7 жыл бұрын

Haha, I've seen it so many times. If you have tons of "shielding", there is no place for return currents if it's not connected to ground. Otherwise, it's a poor antenna.

@Belman5 6 жыл бұрын

Great interview with lots of information, but I'm still confused about grounding. What do you mean by grounding to the negative side of the circuit? I have a bass that's picking up static noise from the nitro finish, and I think it may be a grounding issue. But OMG there must be an easy to understand solution somewhere.

@boxybrown4278 7 жыл бұрын

i have a question about batterys, i have active EQ on my bass guitar and im wondering whats better for my insturment in the sense of consistent energy flow and not damaging my bass from any possible thing that it could damage. Alkaline or no Alkaline in the 9 volt batterys?

@RandyLott 7 жыл бұрын

+Trex, it doesn't matter. You can use any kind of proper battery. It won't make any difference except for how long they last. Hell, you can even use a +9V DC plug pack. However, batteries have no intrinsic noise like a supply.

What about ground lift on amplifier. You can have a perfectly noiseless bass which is noisy without using a ground lift button on the back of your amp or as I first tried, a wire connecting the bridge and the outside of my guitar jack plug.

@sergeiponomarev8316 Жыл бұрын

Is it possible to create ground loops by overdoing grounding connections?

@zachisebi 5 жыл бұрын

I think the shielding (which is a Faraday cage essentially) doesn't have to be grounded in order to work. Then again, it is a good idea to make sure the pots are all grounded.

@sergeiponomarev8316 Жыл бұрын

if it's not grounded, it can become an antenna, if it accidentally touched the signal path

I shield all my basses with copper, last one was a Classic/Vintera 70 without any shield at all. And in all videos of this bass being tested, there's hum and noise. Plastic on poties, not to touch the ground,ok, but then why connect the strings to ground ?

since a pbass would be hum canceling what could the problem be if you have a hum while playing? i have no hum when the bass is idle but as soon as i start playing i have a hum in the back. ideas?

@The12stringbassist 4 жыл бұрын

Informative, but - quite unusually, for a Scotts' bass lessons vid - it did wander all over the place into a discussion about the internals of pickups. I think it may have been better to explain shielding a bass and why it's done, rather than a discussion about ghost coils and suchlike.

How is a shielded cavity going to stop the pickups from picking up outside EM noise?

@chrisstorrier2709 7 жыл бұрын

Vin ....you are creating a Faraday Cage with the shielding thereby stopping any interference

@tubridge 6 жыл бұрын

As long as it stands in a direct line between the noise source and the internal component, even a partial shield will intercept incoming EF before it gets into the electronics. Much of that would be blocked by your own body when you play, but every contribution helps. The floating chromed steel pickup covers on older Fender basses soak up some amount of external EF. A Faraday cage works even though it has more holes than a swiss cheese, simply because it's first in line to offer the unwanted energy an adequate receiver.
