Topic: Can 2 discete pickups share one output jack? |

I have an acoustic guitar that has a transducer type contact pickup. I plan on adding a magnetic pickup to the soundhole. I plan on running both pickups to an A/B switcher so I add different effects/EQ's and can select between them on the fly.
My question is - instead of installing a second output jack for the magnetic pickup, can I replace the current mono jack with a stereo TRS jack and run one pickup off of the ring, the other off of the tip, and share the ground between them?
The other end of the cable could then be split from stereo to two mono plugs.

No reason you can't use a sterio jack to bring the hot side of the pickups out of the guitar .. should work w/o a hitch ... good luck .. sometimes their can be impedance missmatches with some pu combinations .. just make sure you have the correct output wire attached to the sterio lugs and the common to the ground
lug.. |

| As long as you're going into a switch, or mixer, stereo amp, or two amps, it will work. Like Scott said, though, you'll run into problems using both in parallel through the same channel. The low impedance impedance of the magnetic pickup will probably much wipe out the piezo transducer preamp. |

Not a problem at all... there are a lot of 6 string guitars out there over the years that did exactly what you are talking about... The only hitch is if any of the pickups on yoru guitar are 'active and have a battery inside that needs switched off, traditionally, a stereo plug is used to make the groudn connection to the battery... in this case, you would need to look into one of the fancy switching stereo plugs (yes, they are out there!).
In other words, what you want should work. |

Cool - thats good news. I wouldn't ever use both at once. I plan on switching to the transducer for a more acoustic type sound and then switch to the magnetic pickup with some grit for greasy slide work. Running two seperate cables just seemed unnecessary.

In one guitar, where I would not be switching between pickups in a single performance, I wired the most-used pickup hot to tip of a stereo receptacle mounted through the end block. The pickup which would be used least often was wired with the pickup hot going to ring. Both pickup grounds go to receptacle ground. In this way, a standard guitar cord is usually used. When I wanted to use the other (lesser used) pickup, I made a very short cord (6" or 8") with a stereo plug ("male" part) which had the side hot wired to ring. This plugs into the guitar. The output of this short cord was a mono receptacle ("female" part) so that it could be connected to a standard mono guitar cord.
In a guitar where I would want to switch between pickups in a performance, I just used a standard mono receptacle in the guitar's end block (so a standard guitar cord could be used), but wired the pickups to a switch which mounted under the soundhole and slightly inwards so it is not visible.
In both guitars, I wanted to avoid using long stereo cords, which would in my case mean carrying a few different lengths for different performing situations. |
