Hi, and thank you for having me here:-D Sorry, if my English isn't 100% Oxford, second language.. I have been monkeying about with various electronics for about at least 40 years nearly 50 actually..I am about to do some work on my Ibanez AFS75t. It was basically a Gibson style HH setup, two tone, two volume, 3 way switch job. Dropping in a pair of splitable lipsticks, controlled by 3 pushpulls. Looking for split, parallel and "normal humbucker". I think i got it, adapting a diagram off the net. What i need is an experienced eye on it, to confirm that it might work. And if there'd be any issues in it. Don't look at the cap values, random leftover from old diagram. I am looking for spilt, parallel and series options, and I'd really be a happy soldering camper if I got it right, so help much appreciated. And what a site this is, goldmine is what it is.

Hello ibanezernoob . Welcome to GN2. Looking for split, parallel and "normal humbucker". I think i got it, adapting a diagram off the net. What i need is an experienced eye on it, to confirm that it might work. And if there'd be any issues in it. The diagram you presented will work as-advertised if the pickups you use have the Seymour Duncan color codes. If not, we can help you modify to whatever color codes your pickups have. There are two minor issues I would recommend dealing with. The shunting of the unused coils when splitting and having both HBs split to the North coils. Shunting one coil of a HB does work but it can cause a slight loss of treble in the adjacent coil. Better, in my opinion to simply disconnect the unused coil and have the coil being used, connected to hot and ground. I think it's best to split the Bridge to the North coil (as it is in your original drawing), since that is typically further away from the Bridge than the South coil, and will not sound as brittle. If we split the Neck to the South coil, the South coil of the Neck and the North coil of the Bridge will hum-cancel when they are both used together. If you're interested, this is my suggestion to achieve those minor improvements:  |

Much appreciated, thank you. Especially the wiring colours.. This is from the Artec wiring manual, and i think it's counterintuitive the way it's drawn up. ![]()   |

This is from the Artec wiring manual, and i think it's counterintuitive the way it's drawn up. Counterintuitive and confusing. It suggest the color codes are the same as SD but with the opposite polarity. It would be prudent to determine the magnetic polarity of every one of the four coils (I'm guessing the location of the north coil of the Neck pickup is farthest from the neck and the location of the north coil of the Bridge pickup is farthest from the bridge), then do a screwdriver pull-off test on each of the four coils to determine the pairing of the wires to the coils and the appropriate polarity. |

My thought too. Something i'd do in any case, as i have seen errors, either in printed manuals or in finished products..(I had to switch the wires around in one of my car headlights for instance..And with a past in electronics i often saw multi lead plugs with errors.) But I thank you very much for the help so far.

I think i may have spotted an error, (may fault entirely), on the bridge volume..Shouldn't the black lead from the pickup go on the left tab, with pink, rather than ground (right tab/blue)?

I think i may have spotted an error, (may fault entirely), on the bridge volume. Good catch, I completely overlooked that. My guess is they mirrored that pot and push-pull complete with wiring and forgot to move that connection to the left side. In any case, I updated my drawing with that correction. |

In any case, I updated my drawing with that correction. , for now, I still see the old version of the drawing, above. |

Yup! Though in Safari, it must be some other key combo. I opened the thread in another browser (which I shoulda done before) and it shows the updated version.
[edit: and even after making this post, my browser still shows the stale version!]

After the F5 trickery it shows the updated version here. Thanks again. I will return after Easter with an update on the project. I need some more important things done, (such things do exists, according to my One That Must Be Obeyed..)
