I have started to learn alittle about my back neck. Using Jeff Newmans course on beginning C6. I notice when I switch from the E9 to my C6 neck the volume becomes twice as loud. I do not change any position on voulme pedal or Amp controls. Could this mean that my pick-up on my top neck is slowly going bad, and if this is the case where would I find another ShoBud pick-up, or what would be another option for a pick-up. [shobud D10 Professional] and how hard would it be to change. Jack<><

Jack - This may be a switch problem. When the switch is in the E9th position, are both necks hot? On an Emmons double neck that I used to have when both necks were hot (center position) my volume was lessend. ergo, when I switched to either of the necks individually, the volume was greater on that neck.
Hope this helps - Ol' Fred |

| I think Jack meant that his C neck was hotter than his E neck. If that is the question, why is that because my necks are that way also. My C neck is hotter than my E. This is with just one neck or the other on and I know it is wired right. |

Thats right...... If the switch is in the middle position, both necks are hot and have the same power. If I switch to my C6 [hot only] It has MORE power then when I switch to my E9 [hot only]?????? Thanks guys..........

| Check the pickup height. That can make a big difference. |

| I tried that but it didn't make any difference. |

| Well,,,, it should have made a difference. Perhaps your switch has gotten resistive, and is not passing the signal as it should. Then again, maybe your pickup has got some shorted coils. I'd get some Deoxit, and blast the switch. If that made no difference, I guess I'd get the pickup rewound. |

| Ok, the switch is less than a year old and Harry Jackson rewound the pick-ups at the same time. I have just learned to live with it. I also replaced the splitter switches and all the wiring then too. |

Sooooooo This brings me back to part of my origanal question. If the split switch is bad, or the E9 pickup, and If I have to change out either one, or clean up the switch which one of you said you tried and didn't work. How hard is it to replace the pickup or to have it rewound.???? This is an old shobud professinal. I am only two years into playing, so don't know alot about replacing stuff. Thanks............... Jack<><

| Jack, It's easy to change pickups. Email me and I'll coach you through. However, your pickup is probably fine, unless it's a drastic change when you switch necks. C6th is usually a hotter wound pickup, as well as way different string gauges, so you will see a difference there. Take an ohm ready like Craig did, and see what your pickups are doing. 3 quarters stacked should barely slide between the strings and the pickup. |

What does Harry have to say about it, have you checked with him, I'd be curious to see. |

| James I am not losing any sleep over it and just thought I would chime in on the topic. The difference I have is livable yet noticeable. |

| Well, you can settle the question of pup vs. switch by swapping the pickups, including rewiring them. Or you could accomplish the same thing by leaving the pickups in place and switching the wiring, which would reverse the pickup switch. I suspect the E9 pickup is just not as hot. You wouldn't think 17.5K vs. 18.5K would make much difference, but maybe it does. Maybe the thicker strings of C6 also make a difference. Try comparing single strings of approximately the same gauge. |

| It could also be that the magnets in the E9th pickup are weaker. Exposure to a strong alternating magnetic field will weaken magnets. |

I sure do get alot of good information from this fourm, to help me learn about this intrument I have taken up. Thanks to all once again. With all that has been said......... I think I am going to go with the premous that the C6 is wired "Hotter" then the E9. It is also not that bad that I can't live with it. It was just that I wonderd "Why", and you all gave me Great info. I will try the stacked quarter thing to see if my height is right. Not going to worry about it anymore, unless it really gets bad. Then I will holler again for help!!!!  . Thanks again............ Jack<><

| Regarding the stacked quarters height, there are some slight differences of opinion. In general I have heard to use one quarter if there is a cover over the pickup (no magnet heads showing), and two quarters for bare magnets. For single coil pups, you get a better signal to hum ratio the closer the strings are to the pup. I use one quarter height under the highest string, and two quarters height under the lowest string. There is a theoretical possibility that having the strings too close to the magnets allows the magnets to damp the vibrations and adversely affect sustain. However, I find it hard to believe the magnets are strong enough for that. Try raising the pup height until you hear sustain being lost. I have never been able to hear that, but find that string buzz limits the pup height before sustain damping noticeably occurs. |

| Three quarters for the old shobud single coil pickups, like in the Professionals and LDG's and Pro II era shobuds is very ideal. I do not have hum problems. |
