P-bass wiring - different cap values and tone bypass with on/on/on DPDT

[DCikes88]

So I've been wondering if this would be possible, and if so, how to wire that?

I'm thinking: a 3way dpdt switch where I go from 0.1uF cap in the circuit in pos1, 0.047uF in pos2, and bypassing the tone pot completely in pos3.

I've been looking at SDs diagram for standard P bass. I haven't the slightest how to modify it to fit this switch, or what exact switch type would I need, or is it even possible?

The soldering itself is not a problem, however complex the diagram or time-consuming the process, I have no problem taking my time and doing it right.

The standard diagram, for ease of access...

It would actually be easier with an on-off-on switch. You only need one side. Or use a SPDT on-off-on. Wire it like this, and just use the two ends as if they were the two ends of the cap. Up is one value, down is the other, and the middle would be "no-tone."

I recommend a 1meg linear taper volume and a 250k no load audio taper tone.

That severely messes with my ocd, I imagined it graduated by eq, from least to most treble.
But this seems simple and reasonable, so kinda hard to argue.
Tnx, Artie!

So, one end of the switch circuit you posted goes to center lug of tone pot where a single cap would usually go, and the other goes on top of the pot? Am I understanding that correctly? I basically need to replace the single cap with that switch wired as you said?

I agree with Artie's idea, but I've done this before with a blade switch. I actually used a 4 way switch with 4 different caps.

Not a prob. I can draw it up with the on-on-on so that you get the 1-2-3 step action. Gimme a sec.

Yes, but you are krazzy :9:
lol no, just I think I'd be more than satisfied with those three sounds on tap, with two of those having tone control and a direct wired for max tone. Versatile enough for me, and a useful thing to have a single flick to a completely different sound.

 

[DCikes88]

I recommend a 1meg linear taper volume and a 250k no load audio taper tone.

What would that do, how would the pots "behave"?
DuHmB it daun 4 mei.

 

[Clint 55]

Yeah, I just did the 4 way switch to be excessive. The on-on-on will work well and be easy to install.

Wait, do you not like treble on your bass? 1meg lets the full signal of the bass through including all the high detail and it sounds cool. However if you don't want that then just go for 250k. I do recommend linear taper on the volume and 250k audio taper for the tone. Everything behaves well.

 

[Artie]

Make sure your switch has this switching config, and be sure to add the red jumper. Down will be no-tone. The middle will be the "upper" cap, and up will be the lower cap.

It's not that I don't like it, it's just that I like having the option to cut treble further than a single cap can give, and the option to bring out full treble with tone bypass.
Generally speaking, I'm all about that P sound, compared to let's say a Jazz bass.
Let's just say that the neck width is not the only reason I prefer the Precision over the Jazz types.

Oh, yeah I get what the 1meg pot would do. Feels like the opposite direction of what I'm looking for. 250k seems the way to go.

Awesome, tnx for taking the time to draw this out!
So, the end where the caps are goes to lug, and switch end to top of the pot? Or vice versa?

 

[Artie]

It doesn't matter. Just treat those two ends the same as if they were the two ends of the cap. It's bi-directional.

 

[DCikes88]

It's bi-directional.

Ooh a kinky switch, I like it. I'll call the new switch The Tone Peg. Or The Awkward 3way.


Tnx again RT2
