from a newbie.
When I turn both necks pickups on I get a considerable drop in output from both pickups as opposed to using them singly. Is this the norm? |

Hi Jerry,
Sounds like they may be out of phase.
What kind of guitar? can you see the wiring?
Either they're out of phase or there'e a bad connection or contact in the switch. |

If it is a phase issue, swapping the wires on one of the pickups should fix it. As it is, the out of phase signals cause a cancelling effect. (IF that's the problem) |

Many people wire the 2 pickups in opposite polarity so that you can cancel hum by turning on both pickups. I think that's a good reason to leave them wired opposite. |

Yes, it's perfectly normal. Without some sort of isolation circuit or separate controls, one pickup loads down (partially shorts out) the other, and you lose some of the signal...and also get a change in tone (due to the different impedance). |

Donny is correct! Also, many people think this gives the guitar a more Fendery, West Coast sound. |

thanx all. The guitar also sounds like it may have a ground issue. I get quite the hum at a medium volume. A deep hum. I have played many a single coil guitar and am used to the noise and this sounds more like a ground issue. I have to get in there and take a look at the wiring. Most if not all of it is visible.
I don't know the model of the Marlen but it is a '73
D10. |

Jerry; if you email me pictures> sshawaiian@austin.rr.com > I'll put them up here.
The serial number on the plate on the bottom of the steel; read backwards, is the year/month/day of being built.
You can run an extra wire from the ground of the input jack; to a screw point of the changer mounting for both necks....>that will properly ground the pickups to the strings if need be.
What are you running to after your volume pedal???
Yes single coils will hum; but that hum will become more apparent as the windings start looseing through the years in a pickup.
Donny; of course, is correct about when both pickups are on...you will loose full value of each; and they will be somewhat hum cancelling and a little thinner sounding.

Jerry I have a Marlen D10 and the same thing happens to me if I put it in the middle. I just use one neck at a time. Have fun. Bob |
