Hello to everybody from the pyrenean mountains in Europe. This is my first post in the discussion board. First of all I apologise for my bad English and I'll try to explain my problem: I've owned a 1978 series II a month ago and there was no major problem except the "age injuries". A week ago, during a jam session, I heard a very disturbing metallic "pop" coming from the bridge pickup. It seems that medium frequencies are very high in this pickup compared to the neck one. The problem is that every little movement on the strings (slides, etc) or on the body is converted in a metallic and awful noise that disappears when I play with only the neck pickup or when I put the treble trim pot completely down. I've tried to readjust the trim pots and the hum cancelling several times with no results. What I can I do to solve the problem? I really enjoy the bass and I hope there's an easy solution. Thank you… |

Hi Landry (or is Riba your first name?) Welcome! For your technical questions, I guess you will have an answer soon! On the other side of the pond they are just starting to wake up ...slowly ...bit-by-bit. There ARE some REAL technical know-it-all aboard here but I am afraod that you have all intrest to look around for a GOOD guitar-electronics-wizz. There MUST be someone like that in Andorra (or maybe at the French side??? Perpignan?? Toulon?? Bayonne???) I have VERY good memories of my visits to Andorra! Don't apologize for your English. You can direct the Alembicians in Spanish but for French I doubt it. I don't think you have to apologize for your english. Most of the time I hear admiring recation from the other side of the pond that we CAN talk several languages and they don't. Now ...they get lucky that WE do. Anyway ...English IS more or less an international standard in doing business and communication (though I think FRench is still the language of the -formal- world of international contacts: diplomacy, but that's a complete other story). Anyway ... j'espère que le problème avec ta basse sera resolu très vite.; En tout cas ...c'est un 'machin' né pour être joué non?? A très bientôt! Paul the bad one |

Landry, Paul is absolutely right (as he often is) about not needing to apologize for your English. From reading your post you probably speak it better than I do. But Brother Paul, I thought Bayonne was in New Jersey. Sam |

Welcome to the board and congrats on the Series II! Read this thread, especially Mica's post, and see if it helps. |

Landry: If the President of the United States doesn't apologize for his bad english, you certainly don't have to! Welcome to the club. Bill, the guitar one |

Yeah, right, and next you're going to try and tell me that Belfast isn't in Maine. Sorry, Landry, didn't mean to hijack your thread. Sam |

Ok, I'll never apologise again for my english!!! I've read the thread written by Preston for a "pop" in his bass and tried Mica's solution. There's no change... I've tried to connect headphones to the jack connection and I hear both pickups in both ears (even using pikups one by one). Is it normal for a series II electronics? I'm afraid the bass has suffered some changes in his 28 years of life... Landry. |

On a '78 Series bass, I believe it is the case that if you plug stereo headphones into the 1/4" jack, you should get one pickup in one side and the other pickup in the other side unless the jack has been rewired for mono. You might want to take a picture of the wiring connections to the jack and post it here. Try this, gently unplug the two pickup leads and switch them. Did the problem move to the neck pickup or is it still with the bridge pickup? If it's still with the bridge pickup then the problem may be with the pickup. If it moved, then the problem is not the pickup. Let us know what you find. |

Thank you Dave, I'll try to switch the pickups leads. Do you think it's possible to have a picture or a good connection diagram of the series II electronics in order to compare the original system with today one? Regards Landry |

Landry; I don't own a Series II, and at the moment I don't have any pictures of the control cavity of my S1. But it is a good idea. Perhaps one of the S2 owners will notice this thread and post a picture. If not, maybe an S1 picture would help. |

Landry: I just happened to take some pictures of Rory's Series 2 control cavity lasy night. Here you go - I hope this helps. By the way, ever since I got a digital camera, I take pictures of EVERYTHING before I take anything apart or attempt any repairs. Bill, tgo

Here are the news: using Bill's pictures, I've found a bridge between the pickup controls and removed it. I still haven't found the difference but I'm sure it was added by the previous owner. In fact, when I use the bridge pickup, there's a "tin-like" sound that's very disgusting. In a studio record, a few days ago, it was possible to hear all my switch or knobs movements and any little tap on the bass. A great problem for me and for the sound engineer... Will it be possible to have a connection drawing from 1978 electronics? Bill pictures are good but I can't go on specific connections. Thank you all! Landry |

Email me your mailing address, Landry. I'm afraid that my father's schematics from that time were in ultra-fine pencil and quite faint, they do not scan or fax well, but I will be glad to mail you a copy of the wiring harness schematic and the printed wiring board schematic. It's the first on the list for the new schematics, that will hopefully start rolling out in about 3 months. |
