So a few days ago i ordered a Dimarzio hs-3 that i'm going to put in the neck position of my american special. I also ordered a Dimarzio tone zone for the bridge(going to stay with the texas special in middle). My problem is that i want a 250 k tone pot + volume pot for neck/middle and a separate 500 k volume pot for the bridge. Basically what i want to do is to replace a tone pot that goes to the bridge with a 500 k volume pot that only works for the bridge, and make the tone pot i have left work for the middle pickup(and neck, which it already does), and ofcourse make the 250 k volume pot NOT work for the bridge). I'm not too hot on circuitry, if someone could help me with a digram or something i would be very happy.
To put it in few words (noticed it looked a little messy) NECK/MIDDLE= 250 k volume and tone BRIDGE = 500 k volume And ofcourse i want the 5 position switch to work as usual
That link is pretty much exactly what you're asking for. Go with it. Just completely ignore the bottom (as shown) part of the stacked tone pot and everything to which it is connected.
Be aware, though, that the 250K will load the bridge a bit when it's switched to B+M. That's usually a pretty bright, kind of thin position anyway, so the loss of high end might not be such a big deal for you. I can't see any way around it without going to a superswitch.
Also in B+M mode turning either Volume all the way down will kill the entire output. They will tend to act independently until near 0, and then will start to act as dual Masters. This might not be a problem for you, either. If you don't want some mix of both pickups, then why would you switch to this position rather than the one you actually want? If this bothers you the fix is easy, but it has it's own gotcha!
As the article discusses, a 5-way switch is actually a 3-way switch with 2 intermediate "notch" positions. The switch has 2 poles, which is like 2 separate switches joined together and operated by one lever.
In a regular Strat, the 'hot" wires from each of the 3 pickups are wired to one pole of the switch. As the switch lever is moved, each of the 3 lugs is connected to the "common" lug of that side of the switch.
In a regular Strat, the pole to which the pickups are connected is then connected, via jumper wire, to the second pole common lug. This is the diagonal wire you will see in all std. Strat diagrams (unless the switch is an "import" style, where the common lugs are right next to each other).
The volume and tone controls are thus wired off of the second pole of the switch. Study how the switch works, then look at a standard Strat diagram and you'll be able to trace the wires from the pickups, through the switch, and out to the V & T pots, and to the output.
Once you've got that down, look at JohnH's dual-volume scheme. It's a little different. Instead of all three pickups being wired to one side (that is, to one pole) of the switch, only the neck and middle are wired to one side. The 2 poles are not wired together as in a regular Strat. Instead, the bridge pickup with its separate volume is wired off of the second pole, from the 3rd lug. The other lugs of the second pole switch the middle and neck V and T to the output in positions 1,2, and 3 of the switch.
As noted, you will simply ignore the dual-gang tone pot and the wiring to the other half, since you don't want a bridge tone pot.
Don't feel lost, we all started somewhere with this stuff. Me, I was dumber than a box of rocks when I joined this board- some would say I still am! Ask lots of questions if you need to and we'll walk you through this mod, it's fairly straightforward.
ok before i start to pick the guitar apart is there someone who could fill out this paint document with the wires connected to the right place ? im not the sharpest knife in the drawer when it comes to technical stuff:( also since its quite a reconfiguration(atleast it is for me) should i desolder all the wires and start from scratch ? because the current wiring compared to the one i want just confuses me.
