Double to single blender control diagram

[BowerR64]

Came from a Washburn WI-64 it blended the pickup from a single to a double. Kinda neat idea maybe some one can get some use of this.

The leads going to the pickup are green/white = top solid pole coil and red/black screw pole coil.

I wired them like a standard humbucker using the black and white tied together that gave the fat bucker sound green i grounded and red i used for hot. Maybe this will tell you how to wire the pickup your gona use.

Blue is out to the volume and the dash is the white from the pickup.

This just shows how it was all wired in the guitar when it came stock. I didnt like that sound so i cut it all out and wired it like a les paul.

Thats interesting. They're blending from parallel to series. What's also interesting is that they have it wired such that in series mode the total resistance of both pots is between hot and ground. In parallel mode the resistance of only one pot is between hot and ground.

I guess, the proof would be in the pudding, as they say. If it sounds good, it must be a good idea.

Re: Double to single blender control diagram

Damn, how did you figure all that out? i thougth it was just fading from double to single.

How would you wire it so it fades from double to single? maybe thats why it didnt sound so good? i would prefer double to single fade and thats what i thought it was.

Its what I do.

To blend from double to single is just the Duncan spin-a-split mod, as shown here:

The difference would be that you'ld have a dedicated pot rather than using the tone pot, and you only need a single pot. Although, you could use half of one of those if you didn't want to buy anything new. Also, the color codes are slightly different.

Re: Double to single blender control diagram

My guitar has a 5 way blade type switch tone and volume with 2 buckers. The bridge i want left alone, the neck i want to blend and get rid of the tone. can i do that? is there a diagram around for this setup?

The guitar actualy is H/S/H but i never use the middle pickup so its just unhooked but if i need it so there is no dead spots i can hook it back up.

Ide like to turn it counterclockwise for full neck single and clockwise for full neck humbucking. Can i do this with just a regular pot? or do i need the double blender pot thing?

That shouldn't be a problem. A single pot should work fine. Let me chew on this a bit to see if you'ld be better off with a linear or log pot going that direction. Also, I'll see what I can come up with for the 5-way.

Might be tomorrow. Its getting close to Pilsner time.

Re: Double to single blender control diagram

Another question, my friend has a charvel with EMGs and he wants to replace the stock 25K pot with one that has a short taper. He wants to do volume swells but the pot thats in it has such a long taper he cant turn it with his pinking and have it work like he wants.

How can i find a short taper pot or can i rewire a stock pot so the taper is shorter? 25K since its EMGs

I think about half the radius of a standard pot that would give the effect he wants.

Re: Double to single blender control diagram

There is a way to alter the taper of a pot by soldering a resistor across two of the terminals. The thing is, I've never done it, so I'm not sure what the formula is, or which two terminals. If I can find the link to that, I'll get back to you.

Im gona try the spin a split today, the way it is wired in that diagram wich way does it go? clockwise slowly adds ground splitting the humbucker?

 

[Artie]

Re: Double to single blender control diagram

In that diagram, counter-clockwise is full split. If you want the opposite, leave the middle lug where it is, but move the outside lug to the other side. One thing to be aware of, you also effectively reverse the taper. I'm not sure which way it works best.

Re: Double to single blender control diagram

That is one sweet mod man thanks alot!

Do you see any problem in hooking the bridge pickup to the pot also? the 2 leads that tie together from the bridge and from the neck on the blend pot? so then when the bridge pickup is selected i can dial in or out double or single.

Will this cause any weird problems using the 1 pot for both pups?

I never use a tone control but this mod actualy makes the second pot useful i love it.

 

[Artie]

Re: Double to single blender control diagram

That won't produce the affect you want. If you tie the bridge and neck red/whites together, you'll always have the stud coils of those pups on, and in parallel, even if that pup isn't selected.

Thats the brief explanation. Its actually a bit more complex than that. I tried it once. It does create a new tone. It won't hurt anything if you want to try it, it just won't be what you expect.

Re: Double to single blender control diagram

Dang your right, that sucks.

What if i used one of those stereo pots? the one that has the 2 pots stacked.

If i put one set of wires on one pot and the other bucker on the other pot? would that work since they are like seperate pots stacked?

That would work perfectly. You have two options. Use a "ganged" pot that has one knob, or use a dual-concentric pot that has two knobs. (Independent control.) They both wire up the same. The dual-concentric will be a bit more expensive, while the ganged is a bit harder to find.

I think Antique Electronics Supply has them - here.

Re: Double to single blender control diagram

I already have it in the pictures up there. I think im gona do it so when the neck pickup is selected counterclockwise will split it. Then in the bridge clockwise will split it. So its like turning to where the sound is going.

My favorite setup is single coil neck sound, and humbucking bridge so that way i should seldom have to turn it.

Cant wait to try it.

Re: Double to single blender control diagram

If i wanted the stereo pot to split each way i would ground the outside lug on each pot right? Like say i ground the right outside lug on the first pot counterclockwise would split it. Then i ground the left outside lug on the second one, counterclockwise would split it right?

depending on wich way you look at the pot. but one way would reverse the direction.

Re: Double to single blender control diagram

That should work. The only thing you may run into is if the pots are audio taper, you won't have equal "blend" at the middle of the pot travel. It won't hurt anything, just may not be ergonomic.

Re: Double to single blender control diagram

Im not sure, it just says "B 500"

 

[Artie]

Re: Double to single blender control diagram

The ones you show in the pic may also be the "blender" variety. That is, they only have the resistance element go halfway around the pot. They will both be at full on in the middle. Maybe. This is where a meter comes in handy.
