Help needed for Strat 3 coils series/parallel blender

[mihn]

Hi y'all, 
I'm a big fan of this mod I just found by PablOScar1 on Reddit.
www.reddit.com/r/Luthier/comments/147d74o/13_strat_mod_dan_armstrong_mod_blender_mod/ 

"With the Dan Armstrong mod you get 4 new ones:

1- Bridge in series to middle

2- Neck in parallel and out of phase to middle

3- Middle

4- Bridge in parallel and out of phase to middle

5- Neck in series to middle

Then, with the Blender mod you get... let's say two new ones, for now:

1- Bridge in parallel to neck

2- All three pickups in parallel

3- Middle

4- All three pickups in parallel

5- Neck in parallel to bridge

And then, with both mods active, you get two new sounds:

1- Bridge in series to middle, with the neck added in parallel

2- No sound

3- Middle

4- No sound

5- Neck in series to middle with the bridge added in parallel"


Assuming you are on the neck position, turning on dpdt put the Neck and Middle in series, and by using the blender knob you blend in the Bridge in parallel.

I currently have a dual C100k and a dual C250k pot which I can convert to no-load if I have to.

I wonder if using a dual taper pot can help me wire a standard blender mod when the DPDT turned off using the first stack, and using another stack for Armstrong blender when DPDT turned on.
For example in the neck position, when I turn on DPDT it's still only the neck pickup but I can blend in the middle in series with blender knob, as well as the oop blender in pos 4 and 2 just like the standard Armstrong blender. Is this possible?

Thank you for any clarifications as I have zero electronic background and this question might not be making any sense.

Hello and Welcome to G-Nutz2!

Sorry but the link to your diagram doesn't work, so we can't see the diagram you're using. You can't directly link to a reddit feed, you will need to download the image and then upload it to the forum here, using either the Cloudinary upload or the "Postimage Upload" features (the buttons to do so are found at the upper right of the reply window when you reply to a thread).

Sorry I just noticed the link doesn't work. The full mod details can be found by searching google "13+ Strat Mod (Dan Armstrong mod + Blender mod)".

I just want to use Dan Armstrong mod as a blender knob gradually instead of just an on/off DPDT, while still keeping the parallel blender choice. Would a dual concentric pot and DPDT help this?
Just found out the info that no load would not work for series blending, so I guess I will just convert half the pot for parallel blending to be no load

This is my first attempt making a diagram so forgive any aesthetic and logic mistakes. I figure 4PDT would be more useful and I can use a Fender S1 switch for avoiding additional switches. Please let me know if any of these would work or I just miss all electrical fundamentals (ignoring tone control ofc).


This one is just useful enough and really what I wanted, combing parallel and series blend:


With the blender fully counter-clockwise to clockwise, I intended it to give:

4PDT down:
1. N  -->  N+B
2. N+M  -->  N+M+B
3. M  unchanged
4. B+M  -->  B+M+N
5. B  -->  B+N

4PDT up:
1. N  -->  NxM
2. N+M  -->  M
3. M unchanged
4. B+M  -->  M
5. B  -->  BxM



I made another one just for fun which I'm skeptical it make sense, as intended it should adds out of phase options. The aim is to combine Armstrong blender and standard parallel blender:



4PDT down:
1. N --> N+B
2. N+M --> N+M+B
3. M unchanged
4. B+M --> B+M+N
5. B --> B+N

4PDT up:
1. N --> NxM
2. N+M --> M+B oop
3. M unchanged
4. B+M --> M+N oop
5. B --> BxM

Hope y'all can see the diagram. Thanks for any clarifications.

I changed the lugs connection for the series blender pot. Would this be the blending Type A as in series blending thread by JohnH? And my previous wiring is blending Type B? Forgive me I don't know how to read the blending diagram.




Would this work? 





Also I find for the parallel blend pot the best pot value is 200k by wiring 1Meg resistor parallel to C250k pot (2 and 3 lug). This makes the first half turn way more useful but not too abrupt with no-load.

For series blender do I need higher pot value if I’m blending in hot pickups such as HSS, or it doesn’t matter? Should I use log, linear or anti-log?

Would this pot value be equivalently applicable to the series blending or it's entirely irrelevant? I understand that log A taper would still be better than anti-log C for this series blend right?

I've found that log (A) taper works best for series for its smooth sound change across the knob's turning range, and that anti-log (C) taper works for parallel for the same reason.

As for value of the series fader pot, 500K has been too high for my tastes - not enough change from knob position 10 to 5 - and that 250K was better for that. I like no-load pot for this application; there's a noticeable bump when rolling off from 10, but I find it acceptable.
