Resistors on switch to ground

[frets]

Newey,
I’ve been contemplating the resistor on a switch that leads to ground. These would be in relation to “Humbucker sees A500k, Single Coil sees A250k.” I have a mod for an HSS that runs a 470k resistor from the middle on the switch to ground and the same for the neck. Is this wrong?

I think your going to have to draw it to know where this resister is and what it effects

As @angellahash said, I don't know what "middle lug" means without knowing the type of switch we're talking about. The diagram you reference was a Tele set-up with a 4-way switch, which doesn't have a "middle lug" to my way of thinking.

Im going to ignore the TONE
and the Volume becauase the Volume is a PD which makes things complex

1) Neck with 470K, So 1 / ( [ 1/DC Resistance Neck ] + [ 1/470K ] )
2) Neck with Middle and 470K, So 1 / ( [ 1/DC Resistance Neck ] + [ 1/DC Resistance Middle ] + [ 1/470K ] + [ 1/470K ] )
3) Middle with 470K, So 1 / ( [ 1/DC Resistance Middle ] + [ 1/470K ] )
4) Middle with Bridge, So 1 / ( [ 1/DC Resistance Middle ] + [ 1/DC Resistance Bridge ] + [ 1/470K ] )
5) Bridge

Oh i see the Neck can be brought in to play Direct to VOLUME
NOTE when ever the Neck is brought in to play then you would need to add on
1 / ( [ 1/DC Resistance Neck ] + [ 1/470K ] )


So ignoring the DC Resistance and looking on the output and the effects of the Resisters on the Volume

INPUT--------------------------470K-----------------------------GROUND
INPUT------Resistance A-------OUTPUT--------Resistance 500-A----GROUND
10) Resistance A=0 so between Input and Ground is 250K Full Signal
5) Resistance A=250K so but still between Input and Ground is 250K but half the signal and between Output and Ground is 250K
1) Reistance A=500K so between input and ground is 250K No Signal

Shouldnt it be inbetween INPUT and OUTPUT on the VOlume

To get a true 250K / 500K pot .. you need two 500K Pots in parallel
and to turn it on and off .. i would need to Turn on/off two ends

SW1 you have bringing in the Neck, the only reason is when the Bridge as its already there with the Middle and on its own.

I think maybe best to bring in the BRIDGE and to make the Volume to 500K

Then you also have SW2 that makes it in the NORTH pickup on the Bridge

This can be change to Bring the NORTH in to play without effecting the Volume ie staying at 250K

BUT if both up you will get NORTH with 500K


N,N+M,M,M, BLANK

1) N+(Humbucker 500K or NORTH 250K)
2) N+M+(Humbucker 500K or NORTH 250K)
3) M+(Humbucker 500K or NORTH 250K)
4) M+(Humbucker 500K or NORTH 250K)
5) (Humbucker 500K or NORTH 250K)

I've not planned in the TONE yet, i can but hope it wont effect things

My Lapto is going a bit wappy so hard to draw.. JUST example
I couldnt explress the 5 way switch as i wanted to .. But i use both sides

Wait what's the question? In bridge only position, it only sees the V and T pots. In B+M, both B and M see that resistor parallel to the V and T pots. In M only, the M sees the resistor parallel to the V and T. In B+N, both pickups see both resistors in parallel with each other AND the V and T. In N only, the N sees its resistor parallel the V and T. We're back in that situation where anything parallel to anything is also parallel to everything that is parallel to that thing. I mean, put it together and see if you like it, I guess, but...

Like Ash suggested
maybe best to put it together and you can see it happening
dont need to Solder in Pickups just use a a Resister for each pickup

That way it stay in the mind than a load of MATHS and being TOLD yes or no
NOW ya learning like a Boy would learn by what nearly kills you and doesnt work as you want it.

Ah, you must be talking about this:

guitarnuts2.proboards.com/thread/9702/chrisk-brilliance

? 🙂

[Deleted]

Hmmm no
Just thinking that just solder in pickups just use a 100k 200k 400K resisters so you can see how the switching and volume is working

Just a way to do the maths easier

But knowing Frets she would make it with her solderless connectors

...just need a routing in the body that's big enough to contain a breadboard.....

Kneading bread, inside a guitar cavity 😯, is frowned on by me 😉; and I don’t even know much.

gumbo, you don’t knead bread with a breadboard? You prefer to prototype electronics? What about banana bread, or genuine homemade bread? Tastes so good! 🍞❤️


Sry, I didn’t know about electronics on a breadboard. 😔
