Is there a 4PDT push pull pot for guitars?

[psychepool]

Hello.
I'm an old SD pickup user and I'm using SD Pickups on my most guitars.


I am trying to use the EMG pickup for the first time, but I can't find EMG user forum, so I asked a question on the forum of my favorite pickup brand.

I am going to use the EMG 81tw/89 pickup,
Both pickups are coil splittable,
For this, a DPDT switch is required for each pickup.

The problem is that the guitar I'm applying for this pickup is only 1 volume guitar.
I don't want to use toggle switch because it is a rear cavity, it is necessary to make a hole in the body wood to attach the toggle switch, and the size of the cavity is small, so it is difficult to find a suitable place to put the toggle.


If there's 25K push-pull pot with a 4PDT switch, I could solve this problem easily, but is there such a product?
I know of a product called the S-1 switch from Fender, but I found only 250K or 500K because it is made for passive pickups.


As an alternative, I thought of using a built-in relay switch as it is an active pickup with 9v power. But I am concerned about tone loss.
I planned to use two 9V DPDT relay switches(or using 5V through the regulator). Is there any noise caused by tone loss or power sharing by the relay?



Here' wiring diagrams of 81 tw / 89

I've searched but never seen a 4PDT p/p switch. (Doesn't necessarily mean they don't exist, however).

Absolutely. MEC makes them, Banzai sells them.

Slightly off topic, are you going to use the 89 or 89R?

in 25k? nice! ive found 25k p/p dpdt pots before but not 4pdt

Yes. Not cheap though.

89. not 89R

Absolutely. MEC makes them, Banzai sells them.

Oh, that's too expensive to me.
I have a traditional single pick-up guitar anyway, so it is not an element that I would like to implement as important as it costs.

If there is no other product at a reasonable price other than that, I am thinking of two alternatives.
1. Make a 25K pot by attaching a 27K resistor to the Fender S-1 switch 250K in parallel.
2. Use two DPDT relays.

Both methods have their own problems.

Problem with Method 1
-The S-1 switch is also not cheap.
-Pot value made through a fixed resistance parallel connection will not have any problems when turned at min or max, but I am worried that problems will occur when adjusting the pots.

Problem with Method 2
-There is concern about tone loss due to relay.
-Drive the relay with a 9 volt source(battery), but I worried if there's no power source noise.


Can anyone comment on the above problem?

To my understanding, when it comes to noise a battery is the cleanest power source. Not much else I can add to this conversation, but I am curious to learn the solution to your problem!

I worried that there might be interference caused by different circuits or components (emg preamp and relay coils) being shared in one power source.
You can think of it as a concern about the problems caused by using multi dc cable instead of pedal power on the pedal board.
I'm thinking about using a 5V relay by attaching a separate power supply circuit that includes a regulator.

First of all, I'm going to temporarily connect a 4pdt switch inside the cavity and test it to see if the tone is usable.
Based on the results, I decided to split the neck pick-up with the push-pull pot or split both using a relay.
I can also compare the tone of the toggle switch and the tone of the relay.

The S-1 switch is unlikely to be used because I don't like adjusting the pot value through fixed resistance.

The bad point is that splits can speed up battery discharge due to the use of current in relays.


I hope there will be good results.

If you have any other good ideas or usable products, please let me know.
