So, I want to replace the tone pot (I always keep it at 10 anyway) with another volume pot so I can have separate volume controls for each pickup. Also I want to be sure that they are completely independent ie: killing neck all the way has no effect on the bridge and vice versa... Basically I want Jazz Bass style, NOT LP.

I thought I'd be able to figure it out on my own looking at some different wiring diagrams... but I'm still pretty confused.

I am certainly no newbie to soldering... but I am a newbie when it comes to guitar wiring.

I should have the new 1M audio taper pot by tomorrow (to match the original existing volume pot), also I have some resistors I think may be necessary to avoid the one killing the other issue stated above.

It is the Jaguar HH Special

Any and all help greatly appreciated!!

Welcome.

Follow a Jazz Bass wiring but instead of the hot wire from the lower volume pot going to the tone pot, it would go directly to the output jack. Each pickup's volume will function independently of the other.

Also, forget about whatever those resistors are you're talking about.

Thanks.

Thing is I don't want to completely bypass all the switches... and that's where most of my confusion is coming from... but i guess there really is no need for the on/off switches in the lead circuit after my mod, right? what else can i do with them then? (i feel like this is could be a nice window)

how about the rhythm circuit... i think i'll leave that as is for now, not that i'm in love with it, but i feel like i'll let that be a future can of worms... besides, i think i read somewhere along in all my research on this that i can't do the coil tapping/blending thing with the stock dragsters, which i kinda like, and feel as if i'll like them even more once i get the independent volumes working...

You're quite welcome.

You are correct, those switches would certainly be redundant. As to what else they can be used for, well, there's still many options, some of which you've mentioned like coil wiring configurations. One that is gaining popularity of late is the, "Passing Lane" gimmick where by flipping a switch, the pickups bypass all the guitar's circuitry and go straight to the output jack. Another is to where you a 470K resistor can be integrated with your 1,000K pot so that the pickup 'sees' a virtual 500K pot or even ramp up the resistance some more to where a 250K pot is mimicked. Such things will change the dynamics of your pickups and would be even more appropriate when and if you choose to run your pickups in a single coil mode. Then there's series wiring of the two pickups for a thick sound; the list goes on and on.

Keep in mind though that simplicity is always the best for quick adjustments while playing and oftentimes, still the most efficient. Many a time, more dynamics can be had out of a guitar this way rather than loading it up with all sorts of clever devices. Leaving the rhythm circuit intact is positively a good idea too as you'll still be able to control tonality of the pickups.

yeah, i was thinking of maybe using one as a series/paralell switch...

am i right about not being able to do the coil-tapping with the dragsters?

i'm hoping to keep the "strangle" intact, so that i do still have some kind tone adjustment available in the lead circuit after i remove the tone pot.

Although the term is and always was somewhat ambiguous, "coil-tapping" a humbucker is possible as long as the lead wires are accessible.

In actuality, there are four popular understandings on what "coil tapping" is. Ironically, three of them are incorrect. When a switch or some other variable device is introduced into the circuit, here are the four configurations:
1. One coil is wired in series with the other. This is the standard, full power way.
2. One coil is wired in parallel with the other. This yields a much crisper and usually weaker sound from the pickup yet it still remains humbucking.
3. One of the two coils is literally shut off or reduced in its capacity by either outright grounding it out or, utilizing a fixed resistor or a variable resistor (volume pot) to adjust this coil's contribution. This is of course, negates or reduces humbucking capabilities accordingly.
4. One or both coils have a lead wire attached somewhere within the coil's winding (not at the beginning or the end) so that wherever this 'tap' is, only up to that part of the coil is utilized. Obviously, this is the true and correct definition of "coil tapping". Here too, unless both coils are tapped at the same DC resistance, the humbucking effect is diminished accordingly.

interesting... but let's save that for another time! looking at a diagram for the hh special i found, there's only two wires coming of each pickup, i guess the wires that would come out of the pickup and get soldered together are inside in pickup...

back to my original mod:

i think i may have to leave the lead circuits switches somewhat intact... if i wire the bridge pickup straight to the new volume the rhythm circuit on/off won't actually turn off the bridge pickup anymore.

how does this look? My biggest concern here is: can I do that with that pink wire? ie: have both volume's outputs going to the rhythm circuit switch on the same solder point?

Yes with your evaluation of the humbuckers leads and yes because each pickup is wired to the 'out' terminal of the volume pot so they will not (in this context) interact with each other.

great! thanks so much for your help, i'll be sure to post here and let you (and the internet) know how it works out... i can't believe i could find no info online about anyone ever doing this before.

You're quite welcome.

Yes, please do and FWIW, someone has to be first where apparently, you are it!

SLIGHT CHANGE TO THAT LAST DRAWING OF MINE OR THEY WON"T BE INDEPENDENT (or so I'm told, I didn't actually try it that way)

Hey everybody,it worked! completely independent volumes on the Jag HH Special, I'm pretty sure this would work on any Jag actually.

So far I've only played thru the practice amp in my apartment, Vox Pathfinder 15R
But I'm really excited to go play thru my DRRI at my practice space and really see what I can do with it

thanks to everybody for your help! I learned A LOT doing this project.
I can't confirm whether or not other people's schemes worked or not since I didn't try them...

My mod, leaves what was the on/off for the bridge open (ie: it doesn't do anything right now) I probably would use it for a phase inverse but the dragsters won't let me, only 2 wires...

Also, Null.Fuzz at OSG told me that I could've connected Lug #1 of the bridge vol pot to lug #1 of the neck pot and got the same results,but I decided to stick to my design out of pride I guess ;D

Congrats and hold onto that diagram as guaranteed, someone down the road is going to be asking for it or something quite similar. Enjoy!
