Hi there, This my first post, and I'm also a bit of a newbie when it comes to wiring - please be gentle! Anyhoo - What I've done is follow this wiring diagram from a Premier Guitar Magazine article on interesting things to do with you Strat. www.premierguitar.com/articles/21112-three-must-try-guitar-wiring-mods?page=3As a keen country player (but also someone who's never got on with a Tele over a Strat), I was keen to try the Nashville Wiring. This essentially swaps out the original 5 way with a tele style 3 way blade, (Neck, Neck + Bridge, Bridge), then uses one of the tone pots as a volume for the middle pickup. The middle pickup bypasses the switch completely and is routed to the tone pot and then straight to the output of the guitar. When I've tried this, a few things happen that have confused me. If I turn the middle pickup down, I have no sound at all. I would have thought that turning this down would just shut off the middle pickup leaving the two outside pickups to work independently (like a tele). Similarly, turning the main volume pot fully down renders the guitar silent, regardless of the position of the middle pickups blend pot. I've really like to get this working - so if anyone can suggest alterations to the wiring I'd be really grateful. Much thanks in advance. Rob x  |

Grovesnor-
Hello and Welcome to G-Nutz2!
The diagram looks correct and should work as advertised, so the problem must be in your wiring of it. The loss of all signal when turning the 2 pots down suggests a short somewhere (and maybe two separate issues), but it's difficult to troubleshoot these things on the web.
BTW, the Premier article says that one downside of this arrangement is that one loses the middle pickup by itself, but as you note, it should be possible to turn the blend up and the other V pot down to get the middle pickup alone.
No obvious solution strikes me, but I'm still on my first cup of coffee. Let's see what others think.

is this not a case where the standard jazz bass wiring where the pickup hot instead of the output jack should be on the wiper, that way when it is turned all the way down you are shunting the pickup instead of the output?
i personally would keep the master volume wired normally (before i got/gutted/made a volume pedal i'd ride the volume knob for swells), removing the middle only option, but if having a quick way to mute the guitar (only one knob to turn down) isn't important to you, you could move the selector switch/tone pot connection to the wiper
these are my thoughts on the situation
quit
end
done

you got Neck/Bridge Switching to use the Tone and the MAIN Volume
and then you have the Middle on its own Volume
so that if the Middle is Near or on Ground it will ZERO out the Main volume as they are fighting with each other!
Think maybe a Just a Pot to bring in the middle, with a off selection
(im not sure what to call these pots)
basically when you turn if fully one way you hear a click and it turns it OFF
and when on you will just have a Resistance between the Pickup and the Main circuit

I agree with anglebunny.
Premier Guitar is always a fun read, but there should be a health warning since the diagrams are often full of mistakes!
To make that Nashville design work better, use the centre and right lugs of the middle blend pot, and dont ground them. Also, id suggest wiring to the volume pot rather than direct to the jack.
So keeping the switch volume and pickup wiring as they are, wire from volume hot outer, to blend right lug, then blend centre lug to M pickup. This will smoothly blend in the M with low resistance, or effectively remove it as it adds a high resistance. Slightly better, use a no-load pot to completely cut it out. Note this will be full blend at knob position zero, this is how it needs to be if using a standard log pot, to get the low-resistance side of the pot active. Most of the blending will happen in the first few k of pot resistance.
and. btw...his tone pot is wired back to front.
also..page 1 of that series has some PTB mods. the LP version will have very little noticeable bass cut available with most amps.

grovesnor, HI! And  to The NutzHouse!  What everyone above has missed is the most obvious - you are NOT dealing with a blend pot - you are dealing with a two-volume, master tone setup. This has inherent pitfalls that were not pointed out in the PG article. (John's correct, they should be made to publicly wire up their own diagrams, in front of a house full of modders, before any publishing takes place.) In a two-volume layout, you have the problem that angeIsbunny states - when connected in normal fashion (like your circuit), turning down either control kills ALL output, not just the desired pickup(s). Here's a case where you'll have to strongly consider using either a "reverse wiring scheme" (see this link -> Modern And 50s Wiring for details), or move to a properly designed blend control. This isn't impossible by any means, I'm just saying that your source of inspiration is, sadly, not up to snuff. HTH sumgai |

Hi grovesnor In my opinion, Mr Gore is taking serious liberties by calling that "Nashville wiring". At the time of his writing, Fender had been marketing a Nashville Telecaster in various forms including the B-bender for nearly 15 years. None of them used three potentiometers. And they didn't use a 3-way switch. They used a (special) 5-way switch. I can't say what might have been done by various " Music City’s session cats" but for sure Fender never offered such a poorly thought out scheme. Whenever two pickups or systems are joined in parallel with only volume pots controlling that connection, the result you describe (turning either to zero will kill all sound) is nearly unavoidable. I say nearly, because it is possible to back-wire the volume controls such that the input is on the wiper and the output is on the CW end of the resistive element. However, wiring that way solves one issue and creates others. While it makes possible the complete blend-out of the middle pickup or whatever is selected by your three-way, it's absolutely hideous at controlling overall volume. It becomes a massive tone-suck if you try to reduce the overall volume even by a modest amount.
Three-knob solutions worth considering: - Wire the two volume pots 'in series' such that when both are at maximum, the middle pickup is in series with whatever is selected by the 3-way. The downside here is that this won't sound the same as having the middle pickup in parallel.
- Use a proper Blend pot (these are hard to find) to join the middle in parallel with what's selected by the 3-way, followed by a master volume.
Two-knob solution: Use the actual Nashville Telecaster wiring scheme which uses a 2P5T switch (aka half-superswitch) to select: - Bridge
- Bridge + Middle
- Bridge + Neck
- Middle + Neck
- Neck
Of course, since you aren't putting this in the narrow control cavity of a Telecaster, you could use a full superswitch if you happen to have one. |

 just working with a S-Type switch to see if i can get this Nashville N,NM,NB,MB,B effect .. i did think i managed to do without cutting but sadly no  NOW if putting in a STRAT body so got a EXTRA HOLE than Telecaster. What to do with EXTRA one. BASS, Switching for Phase, Switching to change to GreaceBucket or bleed! |
