Thank you for the pic:)

Well my bass does not have such a wire. But I am not sure if it should have one, it is supposed to be the replicate of the 1978 2-bands EQ and the electronics does not look like yours.
There are only three holes in the cavity one for the battery and another to the pickup and another that connect the jack toward the bridge (ground?) . There is no conductive paint in the cavity as far as I can see.

It is my first active bass, I read that the volume and the EQ should not be pushed to max. It sounds weird to me because in such a case I have less output than a Rick 4003.
Well, I like the old smoothie a lot so I'll keep it.

I wonder if shielding the bass would improve the situation since touching a metal part cancel the noise.
But I also wonder if it void the guarantee?

Yeah, all my guitars to date are models without pickguards, so all of the electronics are mounted from the rear.

The black wire you mentioned that exits the cavity toward bridge is definitely a ground. I would think you could add a ground wire from the same post on the jack that you then placed in a similar fashion beneath the edge of the cover, but I'm by no means certain of that.

I AM certain that I would not modify anything myself without first talking with support at EBMM.

Hey all this is interesting. Thanks for posting the pics. I have a feeling my classic is the same, but I will open it up and take a look anyway.

This very well could be a shielding issue, but if it comes down to that, I will reach out to Support again. Checking for a ground being properly seated is a logical first step. I will update.

I opened mine up and we have the same exact wiring. Very, very clean work by EB.

I was not aware that you should not max the volume. Are you sure about that? It does not make sense to me because the old manual for the 2 band version never said those things. I don't max my bass and treble knobs though, I thin kit sounds best with the treble a hair under the middle and the bass a little over.

Suspecting this may just be a shielding thing. I doubt it would void the warranty to shield the inside, but I will check. Honestly, it has not been too bad lately, but I am hitting the studio again and will check there. A little noise at live gigs is no biggie, as I have a mute pedal.

This story of volume I do not believe at all, I was just wondering as I read that on a post somewhere on TB, I think.
Now, I managed to hear that transient high pitched sound but very low on my amp just plugged with a cable. It is pretty difficult to reproduce. However, I know that it is not my amp because my stingray does the same noise when directly plug on my laptop (either on battery or plugged into an outlet). plus I never mentioned that with my others basses. As you said it is manageable and tend to appear less often (maybe I am getting use to keep my hand on the string:rolleyes:)

So my guesses is that is part on the vintage design of these basses and they tend to amplify some kind of interferences. Would make sense as the atmosphere was not loaded of wifi or whatesoever cell phone waves back in the 70's.

As it is cancel while touching a metal part shielding could work but I am pretty sure that here in europe it will void the warranty.
If you shield your bass, please do not forget to post here your results.

Best

The bass was dead silent in the studio last night. So this is an intermittent thing and so far seems like not a big deal. It was at it's worst when I used the quantum battery. So I would say, stick to the duracell and all is well.

I have had two instances of this type of thing, both accentuated with the treble boosted:-

1) In a room with grounding issues and a lot of fluorescent lights. My guitarist colleague's Gretch guitar was affected even worse. However as well as hiss, the usual grounding clicks when touching the strings occurred. This was with my SR4 Fretless.

2) With a particular combo set up (I can't remember the make but it was provided at a jam session and occurred with my 2 Band US Sub 5 with treble fully boosted - it hasn't done it with my LM3 and MB 2 X 10s or any other set up I've used.

In each instance I believe the issue to have been faulty room electrics or faulty amplification equipment.

Not sure if that helps - the fact your bass recorded ok suggests you've either solved the problem, or like mine were, it's some other local factor.
