g'day, today i installed a SH-8B Invader Humbucker into my strat. My setup now is as follows; 1 x Humbucker (Bridge) 1 x Single Coil ( Neck) NO middle pickup 5 Way selector switch 1 x Volume (500K pot for Bridge) 1 x Volume (250K Pot for Singe Coil) NO Tone Pots. My Problem is; No volume control in bridge P/U ,when there should be. No volume control in Neck P/U, when there should be. But for some reason when the Neck P/U is selected and you turn the bridge P/U Volume Down , it changes the tone of the neck P/U. Also playing through my clean channel on the amp is fine, then when i switch on the distortion channel, my guitar sound goes heaps quieter and i have to turn up my master more when i never use to on my old pickups. This is how i wired everything, i know the diagram is probs not the cleanest looking but let me know if you dont understand anything, Thanks alot in advance!

EGN-
Hello and Welcome to GuitarNutz2!
There are several problems with your diagram (and thus with your wiring, since you followed that diagram). First, there is only a single connection to the neck volume pot, it's not doing anything. Second, the bridge volume pot appears to be wired to both common lugs of the switch, meaning it's always in circuit.
There may be some other issues as well, I can't sort it all out this minute as I have a flight to catch. If you can wait until later today, I will get a diagram up for you, or someone else will.
Basically, what you want to do for dual volume controls is to take them off of the selector switch entirely. Each volume pot is wired "across" its respective pickup, and from the pot then to the selector switch, and from the selector switch to the output jack. Again, I'll get something posted for you later today.

El Grupo- Here's what I had in mind. This should be OK, but let's let someone double-check it before you start rewiring. Note that I didn't show the grounds going to the back of a pot, but you can certainly put them there. (I show them going to the jack sleeve, that's just for clarity on the rest of the diagram.) I also did not show the bare wire, as it is understood to always go to ground. Of course, with a five way switch you will have redundant positions at 2,3 and 4 (all 3 positions are "both on"). If you're happy with that, it's fine- but there are other things that can be done such as splitting the HB coils.

thanks for the help newey, i followed your diagram today and still no luck, but it has fixed the problem of the sound cutting in half when i hit the gain channel on my amp for some reason. I just dont fully understand your last line, " Basically, what you want to do for dual volume controls is to take them off of the selector switch entirely. Each volume pot is wired "across" its respective pickup, and from the pot then to the selector switch, and from the selector switch to the output jack. Again, I'll get something posted for you later today." sorry ima newbie at this stuff, i guess ill just keep playingaround with it . thanks

Any problem with your gain channel is not likely to be related to the wiring in your guitar. Sounds like a separate issue.
I don't know what you mean by "still no luck". Does this mean that you are still not getting any volume control from either pot?
Have you ascertained that all else works as it should, the pickups switch correctly and are both operating?
That's what I showed in my diagram. The wiring goes Pickup - - -Vol. pot- - -Selector switch- - - -Output jack.
Were the volume pots new? It is unlikely that both pots were bad, but perhaps you should test them to be sure. But first, let's see exactly how you have it wired now.

yeah they are new gotoh pots, ive basically done it exactly the same as your diagram, but ive run the white wire from the SC to the neck volume pots terminal instead of the selector switch, then the red wire carries that to the 1 & 2 on the selector switch.
Then ive run the hot output wire from one of the output jack terminals to the 0 & 0 on the selector switch.
and the bridge red wire to the 2 & 3 on the selector switch.
Is it possible im running my red wires from the wrong soldering terminal on the pots? or the output jack is running to the wrong pot or pot terminal ?? thanks for any help.

If you are getting output from both pickups, and they are switching correctly, there is no problem with the wiring of the jack or the switch.
If the wires were switched on the pots, but all else was wired correctly, the pots would operate, but in a left-handed fashion.
Please ascertain that you have a good ground from the 3rd lug of each pot to your grounding point. If you are using the back of the pots as grounding points, check those connections.
Did you perhaps just bend the 3rd lug on the pots back to ground to the pot shell? If so, double check that those are well connected. Also, if that's the way you went with the grounds, then the 2 pot shells need to also be grounded together.
If all else is working but the pots are not, it is either an issue with the grounding of the 3rd lug on the pots, or the pots themselves are bad. Since you indicate they are brand new pots, it is unlikely that both were bad, so a grounding issue is more probable.

ok thanks newey, well after mucking around today ive got the neck P/U volume control working , but the bridge still doesnt work, and no sound from bridge. Ill go back and re-check my connections tomorrow and let you know. I have a feeling thats what it'll be. thanks.

egn, First off, Hi, and to the NutzHouse! Second off, newey's been treating you right, you aren't too far from finishing the project! Third, here's what I always tell folks who are having troubles like yours - multiple symptoms and multiple possibilies: When in doubt, always go back to the basics.Let me repeat that for everyone out there in web-land: When in doubt, always go back to the basics. This means that you take out everything that isn't absolutely essential, and connect only those things that are essential. In other words, the pickup (only one of them!) and the output jack. This tells you that the pickup is working (assuming that the output jack is not broken, but your eyes will tell you that, without any further and/or more complicated testing). When you've tested both pickups, each of them separately, then you can insert the selector switch, and make sure that it turns your pickups on and off as desired. Finally, you can add any pots/controls. I personally prefer to test potentiometers with a multimeter first, but that's just me. But if you are suspicious of any pot, then I suggest inserting only one at a time into your circuit, and testing to see that it works. If there are two (or more) pots in a circuit, then you don't know which one is bad, do you? It's like with the pickups - test only one new thing at a time. And that is the whole idea - test only one thing at a time, starting with the essential stuff, and build up from there. BTW, you don't need to solder everything each step along the way. Use what we call "jumper wires", which are simply short wires with small clamps* on the ends. Clamp them to the terminals, according to your diagram, and test. If it works, take the jumper out and solder in the permanent wire. If it doesn't work, then go back and compare your temporary connection to the diagram. If it looks good, then the component you're testing might be bad. HTH sumgai * That small clamp is usually called an 'alligator clamp' or perhaps an 'alligator clip'. There are other kinds of clamps/clips, use whatever is handy.... or cheap to buy! ;D

thanks alot guys, i got it working ;D, thanks so much !!
all i got now is one little problem, why when i turn the gain channel on my sound drop in half ?? then click it off and its back to normal sound level, just means i got to turn it up all the time then turn it back down when back on clean channel , other than that, im happy with the sound.
ill post some pics up in the relevent thread tonight,cheers.

thanks alot guys, i got it working ;D, thanks so much !! Congratulations! ;D My first question is, what happens when you plug in a different guitar - does the amp behave normally, or does it still have a problem? sumgai

Also, In that situation i would be tempted to go for a series/parallel switch for the hummer and a master volume knob..
