3 mini-humbuckers and coil splitting.

Re: 3 mini-humbuckers and coil splitting.

Also, I included a master [...]tone.

Okay, this I don't get: I've got three push-pull pots, and we've designed the push-pull part, but the three pots are volume, tone1, and tone2, just like on my factory-spec Strat, so we're using those, right? Anyway, I'll study it more tonight....

Say, Chill, I appreciate your input: You think this is a worthy scheme? And what did you mean by this part of your response:

which will allow you to use the upper right pole for tone pot switching.which will allow you to use the upper right pole for tone pot switching.

Re: 3 mini-humbuckers and coil splitting.

I missed the part about dual-tone controls completely. :yell:

I'll mod the pic one more time to add that in. Might be tomorrow. I'm getting ready to head out for my boys football game.

Artie

btw - That will also answer your question about Chill's comment about using tone switching.

Re: 3 mini-humbuckers and coil splitting.

Ok, I editted the pic to include dual tone controls, and to make it easier to see how the middle switch was connected. The cool thing is, you can connect your tone controls to any combination of the terminals I have labeled A - E.

For example, I show it with one tone for the middle, and one for the neck & bridge. You could connect one to A & B, and the other to C & D, and you'ld have one control for the neck, one for the bridge, and none for the middle. The possibilities are endless. (Well, almost.)

Artie

For example, here's two more ways to do it:

A & B is neck.
C is middle.
D & E is bridge.

Chill explained it perfectly.

Only because I had an awesome diagram to work from.

Wow! Engineering-on-demand -- this is great! That diagram is a thing of beauty.... I do have to admit it seems a little daunting, but I'm too naive to let that stop me. :laugh2:

I'm thinking I'll go with Tone1 controlling neck/mid, and Tone2 controlling bridge. (I tried coming up with a way to cram a 3rd tone pot in, but I gotta draw the line somewhere! You don't wanna know what kinda ideas that was giving me....)

Finally, to test this circuit as I go, I just max out all the pots, and use the ohmmeter to measure the resistance at the jack to see if it seems reasonable for each position of the switch, right?

Meanwhile, I've got to wait for some of the parts to come in, so I have time to study this and try to translate this to some sorta wiring diagram.

Thanks alot!!! :dance:

Re: 3 mini-humbuckers and coil splitting.

For any of you spectators keeping score, neither diagram posted so far is exactly what I'm building: The first diagram is correct in terms of the push-pulls and basic switch wiring, the second diagram is correct in terms of tone-controls and volume control.. At least, that's my interpretation....

Re: 3 mini-humbuckers and coil splitting.

This diagram should be complete, with the tone controls configured as your last post stated.

Re: 3 mini-humbuckers and coil splitting.

Okay, got the CustomCustom trembucker dropped in and the wiring all "prototyped". (In other words, everything's wired up but I didn't solder anything yet.....) I've only got the bridge pup in so far....

However, I think I've got the tone pot wired wrong; I've got the cap for it hanging outside of the guitar, and trying different values doesn't seem to matter. It just doesn't act like a tone control, it changes something but I can't describe what it is.....


Anyway, for this particular schematic in this thread, how should it be wired? I don't recall at the moment, but I think I tried one way, that didn't work, and then I consulted one of the SD schematics and wired it up as

-- left terminal: open
-- middle terminal: to cap, then to ground
-- right terminal: input, as from the schematic in this thread (i.e., connected to one or more terminals on one pole of the super-switch, depending on what pups this tone control should apply to)

Generally, its better not to refer to the terminals as "left" and "right" simply because we don't know if you're looking at the pot from the front, back, lugs pointing up, lugs pointing down, etc.

So, if the pot is like this, use the terminals with the arrows:

With those two terminals, it doesn't matter which one goes to the cap, and which one goes to the point you want to control. With that in mind, note that the following four configurations are all electrically identical. Doesn't matter which way you do it, the tone control will work the same:
