hi cbg people i have a question regarding wiring diagrams. i want to make a double neck cbg, with 2 string fretless bass coupled with a 3 string cbg. i want each to have its own vol and tone but all use the one jack, so i guess its a 2 pickup 2 vol 2 tone 1 jack. can you point me to the best wiring diagram for that. or do you think it would be better to keep the bass and cbg wired to two different jacks? thanks for all good work done on cigar box nation...

I want to build this also. I googled "double neck cigar bass" and saw this. I have P bass pickups to use for bass. Will check back from time to time. Still in planning stage.
Switchable jacks come in stereo or mono types - I tend to use stereo as the extra connection gives more grip to the jack plug (you just ignore connecting to the middle lug)
They have a springy inverted L which connects to the other side so when not plugged in the signal passes as though it isn't there. When a jack plug is inserted it lifts the arm of the inverted L shape so the signal goes to the jack plug.
I buy them from a UK seller but if you cannot find them locally you can get them off ebay - cheapest I could find with a quick search

If you were to use this rather than having to keep switching amp cables the 3way would let you select the pickup in use (or both if you are switching between bass and 3string during a song). Using an extra switchable jack before the 3way switch would still let you have the option of playing the pickups to different amps but unless a cable is plugged in the signal follows the normal pathway and would work as per the above diagram.
If you are interested in this idea it is simple to do - I can post a photo of the jack I mean in the morning UK time :0)
thanks david that would be great. i will check out article, off to walk the dog in morning sunshine here, have a good one...
For the output jacks I tend to use switchable jack sockets which give you the option of sending the bass and 3string output to different amps or both signals to one amp if you use 1 jack plug.
Do you want to be able to turn off the bass circuit or the 3string circuit when using the other to cut down on the risk of getting sound when you catch the strings to the circuit not in use?
Seymour Duncan has loads of wiring diagrams http://www.seymourduncan.com/support/wiring-diagrams/
for ideas. Two pickups, 2 vol, 2tone and a 3 way between them is a typical Les Paul set up so check out the humbucker options as a starting point.
thanks david great advise, it looks like i have a couple of more questions to answer myself. i am using magnetic pickups one pick up per circuit, i was thinking of having both circuits on at the same time all the time, but that does sound like it could be a little noisy.
can i use maybe two separate circuits and two separate jacks and when i want to play both i could use one of those two jack leads that blend into one lead to the amp.? i will look into the seymour duncan wiring diagrams and see if i can upscale myself to working out three way switches etc.
thanks again for your help, much appreciated...
