sorry a use a translator.
hello,
after having repaired my cards Preampli at Alembic, I always a buzz. buzz come from micro round, I wanted to know if it was repaired by a luthier? and how much a microphone nine or opportunity?
mer?i
-
Nice translator - neuf is nine if it isn't new, and occasion is opportunity if it isn't second-hand. Not sure what got translated as round?
Jolie traduction! Quelle micro est la source du buzz?
-
thanks Adriaan
Buzz at the neck pickup
-
I will take a short video of the problem
-
Tu as d?j? essay? d'ajuster les quatre petits tournevis visibles dans le dos de la basse? Les deux au milieu sont pour supprimer des buzz, un pour chacun des micros. Les deux autres sont pour r?gler le niveau de volume maxi des micros.
-
Oui j'ai tout fait,le buzz est toujour la!!!

Would be helpful if you can post a clear close-up picture of the electronics cavity so I can see the type of pots you have.
Does it only happen only with the Q switch in the maximum position?
Do try rotating the pot back and forth a good 30-50 times to exercise it. This might clean the pot since it was stored for a few months with no use.

Thank you for your prompt response Mica,
I shot several times pots, but the noise does not disappear!
I've made a gallery of the cavity,
Can you send me a pickup connections card preampli because they are bad (you can see the photos on the tip of green thread is not original, and other connectors are tired)
I said the price of everything!
Thank you to soon
a question; can this come from my neck pickup?
-
You can switch the pickups very easy, just switch the connectors ;-)
Marked with the orange arrows (if i'm not mistaken)

Edit: Maybe it's plugged in the humcancceler input?

I haven't been keeping up with the translations, but the bottom connector in the picture isn't plugged in all the way. Also, the top connector isn't standard and, though it's hard to tell in the picture, the wire leading to that connector looks worn.

And try Flip's (FC) suggestion. If you switch the pickup leads and the neck pickup is still buzzing, then you've isolated the problem to the pickup. If you switch the pickup leads and the bridge pickup is buzzing, then it's not the pickup.
-
To determine if the problem is in the pickup or electronics, swap the neck and bridge pickup connections as suggested. This image shows where the Hum X pickup should be connected:

If you determine the pickups are ok, we need to look at the filter pot.
To clean the pot, you can't use spray (shot). What it needs is mechanical rubbing by rotating the pot. My dad suggests really wearing your hands out and rotating even up to 500 times to clean. It will not harm or wear out these pots.
The problem is that your pots are apparently left-handed rotation. While you are trying to clean your pot, we are looking for an old-stock left hand rotation replacement. While a new one can be built, the price will be amazingly high, so I hope that you are either able to clean it or we find and old one to send you.

I forgot to tell you that my plot (volume + filter) are in reverse.
I buy the low left-hander has a right.
Is it possible to put them in the right direction?
Indeed noise comes from the plot!
The buzz when he just stick the microphone (it was open
What to do? Buy another, or I will mail you to fix me (is what it costs)
Thank you all for your information.

Mehdi, could you post that in French? The translation tool that you're using is terrible - I'm sure I can do better than that.

Ok Adriaan
French vesion:
J'ai oubli? de vous dire que tout mes plot(volume+filter)sont a l'envers.
j'ai acheter cette basse gaucher a un droitier.
Est-il possible de les remettre dans le bon sens?
Effectivement le bruit vient du plot!
Le buzz quand a lui ,viens du micro manche(il a ?t? ouvert
Que faire?en acheter un autre ,ou je vous l'envois pour que vous me le reparer(est combien cela coute)
Mer?i a tous pour vos renseignement.

OK - here's the English translation:

I forgot to tell you that all the pots (volume+filter) are in reverse. I bought this bass from a right-handed player. Is it possible to put them in the right direction?
Actually the noise is coming from the pot!
The buzz itself is coming from the neck pickup, which has been opened. What to do? Buy another, or send it to you to have it repaired (and how much will that cost).
Thanks to all for your help.

Your welcome!
