Source for 4pdt push pull pot?

Re: Source for 4pdt push pull pot?

Actually, beau, by moving the connection to the tone control from the middle lug of the vol pot to the outer lug, you have put it directly INTO the circuit when the vol pot is bypassed.

But, that being said, I do see a potential problem with my suggested wiring. When the vol is bypassed (and the vol WILL be bypassed) the vol pot will now control how much of the current will go to the tone pot acting like a blender pot for whatever the tone control is set to...the tone will only be completely bypassed when the vol pot is turned down. But if he wants a vol bypass, that would indicate that he keeps his vol pots turned down (otherwise, why would he want to bypass them?), and therefore when the bypass is in effect, there would be very little signal going through his vol pot to the tone pot anyway. Thus, the bypass would totally bypass the vol and nearly completely bypass the tone.

So, this brings me back to the original post and a question for your client. Why does he want to bypass the volume? I certainly can understand why to bypass the tone, and I have done this on several of my own guitars. It makes a big difference. It makes it very easy to switch from one tone to another (bypassed) and then back again to the exact same original tone (like when going from rhythm to lead and back again) without having to try to "find it" by turning the tone knob. Bypassing the tone may also give a slight boost to output as well. A second question, related to the first, is...does your client USE his vol controls? If he does, then why does he want to bypass them? If he doesn't use them, then why does he want to bypass them? I know there are some players who never touch their volume controls, and that's fine, but then why even have them?

Another simple solution would be to eliminate the vol pots in the guitar, have a bypass switch for the tones, and have a volume pedal for when he wants control over his volume. Or keep the volume pots (if he really wants them and uses them), eliminate the tone pots completely, have a bypass switch for the vol pots, and have a volume pedal modified to act as a master tone control.

Thanks for continued thinking! I used to run into blowers all the time, but seems theyre less common now? The reasons for the bypass are
1. the change in timbre and increased output when bypassed

2. easy to switch back to previous settings with on click

So they definately want all 4 controls to work as usual plus bypass.

The reason for bypassing tone and volume is this is the way i have wired in the past using a 4p2t. if we can get the same or similar sound with a 2pole, it doesnt matter how its wired, howevere, i need to be confident that it will work as i am doing 3/4 of a jimmy page at the same time and need minimal trouble shooting.

With that said, what do we think we can do with 1 dpdt, ie what would #14 do? Or would tone only bypass get the same sound with dpdt (I can't see that solution, but could be missing it).

If we're not sure, I'll fallback to bypass for neck only.

Thanks again!

Re: Source for 4pdt push pull pot?

Guys, I'm starting to lose focus on this one- I've decided to abandon the 4p2t, to do the neck pup bybass, but now it's starting to look weird in itself (I've been thinking about this way too long).

SD link and diagram follow-
So this will give us a dpdt bypassing the neck pup-

However, the bypass side of the switch goes to the + jack and the rest of the circuit (including the switch and other pup) also connect to the positive jack-

So don't we have the same problem we started with where signal will flow back down thru the 3 way and into the other pup's controls?

I'm just about back to the idea of paying $100 bucks for the 4tdp from the UK (no, not serious:)

I'm sure you guys are tired of this thread, but really appreciate some more input-
Thanks again.

Re: Source for 4pdt push pull pot?

What's missing is all that wiring in the 'standard guitar wiring' that is also connected to the jack. Need to trace the signal through all of it to tell if it will work.
 
Re: Source for 4pdt push pull pot?

I've found a diagram that shows more than the SD- It appears that the 3 way is isolated and only a single lead goes to hot output-

If this diagram works, I think I can mod it for my purposes (bypass neck pup, paralele bridge pup, series and ooP), but note that the creators seem unsure of the diagram

Guys,
Thanks for the help in this thread- I'm going to close out this thread with the current wiring (that we don't believe works) and open a new tread with a new title to see if we can get other perspectives-

Thanks again for being further down the road than I am!


Peace,
M
