Motherbucker wiring diagram

[daedolon]

This is the diagram I created for the motherbucker:

[SWITCH POSITIONS]

DOWN - DOWN = Series
UP - DOWN = Left Pickup
DOWN - UP = Right Pickup
UP - UP = Parallel

I'd just like some advise. Is this worth the trouble, and will it work?

[UnklMickey]

i really liked this circuit 'til i saw what happened with:

DOWN - UP = Right Pickup

everything gets shorted!

the other positions of the logic seem O.K.




U.M.

[daedolon]

Well. That sucks.

I didn't see that before, I don't know how I could have missed it.

I guess it's back to the drawing board.

Thanks for finding that btw. Atleast I can correct my mistake before it's too late.

[UnklMickey]

stay tuned, i think i've got it figured out.

need to draw it out and "test" it.


later today, or first thing in the a.m.

hey Daedolon,

try this on for size. i copied your image and edited it.

first time i've ever used mspaint to do a drawing, (or posted an image), so it's a bit rough.

it was designed with the following targets:

• no coils ever shunted
  
• no coils "hanging from hot" when unused
  

should work as you originally intended. i've checked it myself, but as you have already learned, things get past the author! (maybe we can enlist the help of JohnH or Wolf to proofread it)

if this proves to be good, we'll have to clean up the drawing and create a schematic, cause i think we've got the "mod of the month" here. (unless of course it's already been done?)

[JohnH]

I think that is great! and I believe it is correct. You have one pole on each switch to do the basic tone changing, and the others work together to stop the disconnected coil hanging off the hot connection. I think that is the right way to do it.

As you pointed out, it can be applied to two seperate pups also. With the Humbucker, it is a good alternative for the use of an on-on-on switch for series/single/parallel, which is a switch type not available in many countries - Nice!

[daedolon]

Wow, was definitely not expecting that. Thanks a lot, I’ll give it a try!

[UnklMickey]

alrighty then, looks like we have a few more things left to do:

• wiring and real-world test
  
• create generalized schematic and wiring diagram
  
• name this puppy
  
• post it to the schematics sub-board
  

so i thought, since the idea came from wiring the motherbucker -- ToneMutha? or maybe Simplex?

give me some ideas guys, cause this will be my first "published" circuit on this forum. i'd like to have an appropriate name for it.

thanks,

U.M.


just had another thought for a name. the Double-Double? or Double-Duplex?

(TWO-switches, TWO-pickup coils, DOUBLE-pole, DOUBLE-throw)

or is that too trite?

[daedolon]

Just changed the colors to fit the pickup.

Works great btw. Thanks again.

As for a name... WDMB Motherbucker stealth switch?

i was thinking more along the lines of a name that might allude to the functionality, or the switching arrangement.

i get the motherbucker part, and the stealth (push-pull switches on the pots).

but where does the WDMB come from?

U.M. I've been watching this diagram evolve. Other than not being able to turn off the bridge and neck pups, this diagram would also work for the two 3-position switches on my Mustang to give me series/parallel. Correct? May need to get the soldering iron out again.

[UnklMickey]

mustang,

don't heat up that iron just yet!

that switching configuration i've devised for daedolon's arrangement is designed around two-position switches.

some ugly stuff is bound to happen if either (or both) of the switches are in the center position.

if you can find some two-position, dpdt slide switches in the appropriate size, with the right spacing on the mounting holes, you might want to replace the switches and use this circuit.

otherwise, check with JohnH or Wolf. one of them may already have a circuit that fits your needs with the switches you currently have.

WDMB is the model code. Stamped right on the back of the plate. And it's listed on the site.

WD = Wd music and MB = Mother Bucker

[Mustang]

U.M. you may be on to something. On first glance, I thought the switches where electrically equivalent because the center two terminals on each side of the 8 terminal switches are shorted together. But, as you suggest, on the Mustang wiring in the middle switch position, both sides of the pickups are isolated. In this circuit, one side would be connected to ground and could be an issue.

Do you guys think that these kind of pots would fit into the control cavity of a tele?

And if they did, what sort of cool stuff could I then do with my 3-way?

probably, but you might want Daedolon to give you a measurement on the depth required, before you actually buy them.

seems like the wrong way to go if you already have a slot for that 3-way, unless you are planning to add another pup. or change one to a HB.

maybe a better choice would be to get a strat superswitch (somebody help me out here, do they have the same mounting dimensions?). with the 5 positions, you could have the 4 sounds in this mod, plus series out-of-phase. and you can arrange them in any sequence you want.

U.M.

[eljib]

I already tried that, and the switch fit neither the mounting holes nor the inside the of the cavity (so it ended up in my strat with the help of John A's S-tastic mod, which kicks butt so bad I decided I had to get the same options from my tele). And that's what got me interested in this wiring config.

It seems like I could add phasing with the 3-way, and maybe some other stuff...but, since I am very unfamiliar with the limitations of the parts we are working with, the stuff that seems to me like a good idea is actually not possible.

Please advise.
