Location: Always beautiful canyon country of Utah | I have a 1681-9. When I plug it in only 3 strings are electrified. I can change it to the other 3 strings by switching the plugs from the pickup under the bridge. And it only works when plugged in to the monural jack. Also the sound only comes out of one speaker (plugged into a stereo system). Does anyone out there know if this means that one of my preamps is bad?? And if it is plugged into the monural jack should the sound come out of both speakers?? Hoping someone out there is more familiar with this than I. If I plug the cable from the stereo system into the stereo jack on the guitar none of the strings are electrified. I bought this guitar used. Thanking in advance for any help which I might receive. always nerdy dave |

Location: Boise, Idaho | All the strings should put out sound when plugged into the mono jack. Start there. If they don't all work on the mono jack, I would switch the plugs at the pickup and see if they all work.
Beyond that, I can't help. I've never played mine into a stereo system, so I only know how it is supposed to work on an amp. I think you need a special cord to make use of two amps out of the stereo jack. |

Location: Always beautiful canyon country of Utah | Thank you for your reply. Only 3 strings have sound at the mono jack. If I switch the plugs inside the guitar (at the preamps) then the sound switches to the other three strings. That is why I think I may have a bad preamp. |

Location: Colorado Rocky Mountains | Is the battery fresh? Based on my ecxperience, the first sign of a dying battery is loss of sound from half the strings regardless of the output jack used. |

Location: SoCal | Clean out the plug on the preamp that's not working. Spray it out with some DeoxIT or something similar. I've had this happen on several of the reissue 2 knobber preamps. But check the battery as well..... |

Location: Always beautiful canyon country of Utah | Battery is 9.7 volts and I replaced both of the small plugs on the preamp where the pizzoelectric pickups plug in. So they are clean and functional. Thank you all for your replies. Does anyone have a preamp assembly to sell?? It is the old two knob type. |

Location: SoCal | It's the reissue, redesigned 2 knob preamp. Talk to Al. He can probably get one for you..... |

Location: Always beautiful canyon country of Utah | Can it be a reissue if it was made in 1981?? |

Location: SoCal | Maybe not. I've never heard of the problem you are having with the original. Only the reissue..... |

Location: California | How about the stereo pickup? It may be some bad crystals on the pickup, were you able to buy a new preamp or a new pickup?
Interesting to know what the problem is, let us know what you found.

Location: Texas | Boy, you can certainly find yourself on the wrong side of the guess here and end up buying something you don't need...is it a contact problem on the Piezo side or a pre-amp malfunction?
Surely Al or the MS would have a better way of isolating the culprit, other than a flip of the coin.
And as HW requested, please let us know how you resolved it, so that the next poor soul will have your experience to benefit from.

Location: Always beautiful canyon country of Utah | Of course I will let you know what it turns out to be. I think the fact that when I switch the plugs (at the preamp) the other three strings are amplified means that the pizzoelectric pickup is good. This would also seem to mean that the receptacle for the cable is functional. At this point I am planning on replacing the preamp. Mike has one I can buy as soon as he locates it. |

Thanks for the update. I am quite sure I will want it when you locate it. Just bought a new amp so I am ready to go electric. Just let me know when you locate it. |

Location: Always beautiful canyon country of Utah | Problem is fixed. I replaced both of the female jacks on the preamp and I now have sound on all 6 strings. Only one of the jacks was bad (hence the sound on only 3 strings) but I replaced both just because I was in there and my soldering iron was hot (plus they come in a pack of 2 at Radio Shack).
Just letting folks know as I promised I would earlier in this thread. Merry Christmas everybody!! |
