OK, so I really love my spector, But the EMG single coils are driving me f***ing nuts. They hum. A lot. And it bothers me. I know, they're single coils, and single coils hum, but I want to change that. So, I've been looking into ways of eliminating hum, other than noise gates or suppressors, which mess with your sound too much for my taste. I'm intrigued by the EHX hum-debugger. So, I was thinking about getting one and mounting it inside the bass. Then I realized, wait: instead of shelling out 120 for one of those, why don't I built my own and mount that inside it. Problem is, I don't know how the things work. It sounds like it might be a notch filter to me, but I don't know much about this kind of stuff and I can't find a schematic or anything anywhere.

So, a few questions:
1. Does anyone know how the pedal works?
2. If it is a notch filter, is that all I need to put in, or are there other necessary components as well?
3. How would I install it, whatever "it" happens to be?
4. Would an on/off switch be worth putting in?

these things have intrigued me as well. What it is supposed to do is filter out all ground loops, or anything related to grounding that causes buzz. I'm not sure exactly how they work, because i think they are passive. You have to remember that Single coils will always buzz. That's 60-Hz for you. People have been looking for single coils to stop humming for yeares. That's when the humbucker and noise gates came about. P90 and single coil buzz were too much for some people, and not hot enough. I dunno what to tell you. Order one from musiciansfriend and try it first, this might not be your solution..

I hate when people oversimplify a pedal build...

That said: I have never heard of that pedal. Doesn't sound overly simple or easy to build, either. Buuuuut I DO have a schem/layout for a "45-90Hz hum filter" that I'll give you if you are interested. It's a fairly simple build.

^That does sound good. Where could I get my hands on it?

Sorry to not be of help, but aren't EMGs supposed to be silent. Perhaps you could shield your guitar?
#7
^ You probably only have experience with the humbuckers. Those are dead silent. Their J-bass pickups still get some hum. Less than most passive j's, but it's still there.

Not entirely, but it reduces it greatly

1. No
2 N/A
3. You'd probably have to expand your cavity
4. No

Personally though, I don't rush for the biggest waste of money I see. I, crazy person I am, like saving money so I would get this.
#13
^ I was going to build my own to save money... Still $10 is even better, though Invader Jim's pedal sounds good too, you really need to get on uploading it, dude. Anyway, where would I put the shielding? there's no pick guard or any other convenient place to mount it. In fact, I don't think I could put it under the pickups without completely disassembling the body.

Why not just replace the pickups. Get real EMGs. EMG make very low noise active pickups, like with a battery in there and hum simply never happens.

I know EMG has licensed and possibly designed some lower end pickups to be branded with their name. Never heard any good of them.

Put something serious in there and forget it.

You mean the one Bobbert posted? Why? It's right there.


I forgot the site it was on. Might have been GGG. I think I remember MSPainting the watermark out of it, and it looks like the GGG style.

They are real EMGs. Again, I remind you all that they are J-bass pickups, ie single coils. single coils hum, and it's damn hard to get rid of the hum in true single coils without

a. reverse winding one of the pickups and keeping them at the exact same level
or
b. some kind of electronics mod pedal, etc.

I feel like an idiot. I missed the last two posts on the first page... this is embarrassing...

Anyway, thanks for the schem !

It does get rid of a fair bit, but cause EMGs are active they do not need shielding.
