    Default Help with Wiring Diagram - Master Vol & Tone, 7 Way Strat Mod

    Good day,

    I need some help with wiring a 7-way Stratocaster mod, but only with 1 master volume and 1 master tone using a DPDT Switch. In this video, the guy wires his pots oddly, and I got confused as to why that circuit works. More importantly, it seems like that circuit would only work because of the 2 tone pots, which defeats the point of having a master volume/tone.

    Any help would be greatly appreciated.

    Thank you,
    GreatOz

    Just use the diagram in the Premier guitar article, choose whether you want the volume or tone to serve as the switch, and wire the rest as written.

    From the Premier guitar article:

    If you only want one tone, ignore the tone connections in the pic above and send the input of the volume (as depicted in the above pic) to the tone as well.

    Do the tone like it's done in this diagram taken from the seymour duncan site (ignore the humbuckers vs singlecoils, for 1vol + 1tone it doesn't matter, once you come off the selector switch the hot signal is the hot signal regardless):

    These are quick-connects, but the connections would still be the same..

    The pickup selector has 2 connections per lug (stacked), it is an Alpha 5-way And I have my connections on lugs B0(output)-B3(neck)-B2(middle)-B1(bridge) with ground on the far left. Basically you need only one side (pole) of the selector if you only have one tone..

    This is how the different selector switches are numbered:

    Thank you. That should speed up wiring when it comes in.

    So is this a correct diagram for a DPDT switch used?

    The big change from the design in the link above is I wanted a bridge-on switch instead of a neck-on.

    I feel like I screwed something up with DPDT.
    If there is anything that you need clarity on, please let me know.

    Edit: Forgot the wire for the tone on the capacitor.

    No. You're on two sides of two internal switches. Take your top-left connection, and move it to the center terminal right below your top-right terminal.

    Technically you didn’t need a DPDT, a SPDT would have done it. A DPDT is basically two separate switches side by side with one toggle. The A1-A3 side doesn’t connect to the B1-B3 side unless you solder a jumper across their lugs. You originally had it drawn thinking the two sides were already connected.

    Yeah, I figured out I didn't need a DPDT after I already bought one lol. No biggie.

    Thanks for the help!

    I have a treble-bleed circuit on the volume pot, does that change the circuit at all?

    Thanks,

    Nope. Except it makes it brighter when you turn down.
