Here's my take on a Tele with a Blend pot. It started out as a simple T-riffic style with a Broadcaster style blend (Neck blending with 100% Bridge) with no extra switches. Saw that the series could be blended as well, and worked to add that in. Then kept adding small mods and it took on a life of it's own.
While it can be done with modified single gang pot, using a dual gang pot made everything simpler. Easy to disassemble and convert to a no load for the series wafer, plus you can swap the wafers for different values and tapers.
Came up with two diagrams, the second one adds a push/pull for a bit extra. There is even a spare pole on the 5 way blade switch for more mods.
The five pickup selections are Bridge, PHOoPR, Broadcaster blend, and series blend with SHOoP and Series. When in the two series positions, and when the Blend knob is rolled all the way back, you get Neck and HOoP. In the Bridge and PHOoPR positions, the Blend has no effect. By making the series wafer a no load, you take the blender out of the system and get full series.
Took the idea for the PHOoPR (Parallel Half Out of Phase/Resistor) from JD Omniac Peavy Tele to add the resistors. The resistors add to the phase cancellation, larger resistors will cancel it more. The grounded series resistor before the HOoP Neck and one after the Bridge seem to fix the weak bright sound and balance it out compared to the usual PHOoP, and a more useul sound. Maybe even the Bridge and Middle sound like a Strat as boosted.
Seen suggested values are 1k to 6k2. Initially tried 4k7, and had too much cancellation, smaller maybe be better. YMMV depending on your pups.
If you don't want to use the resistors, you can just replace them with wire and just have PHOoP.
With the P/P No Load Tone pot, it has many functions. Pulled up in the Bridge position, it's the Arlo Cocked Wah mod. In the other four positions, the .0047 and .01 caps in series produces a .003uf cap to ground. Much like the Eldred Cocked Wah mod. That was by accident this happened, serendipity.
It also switches between two tone caps instead of assigning tone caps to the blade switch. This can be left out if you prefer a favorite tone cap value.
The Tone pot need to be made a no load to take full advantage of the two cocked wah tones, or just for the pups with no tone.
For Volume and Tone, you can use your choice of 250k to 500k pots. The 500k volume and 250k tone works well together.
The Blend pot can be a 100k linear dual gang pot, or switch them around to suit the purpose. It need taken apart to make the series wafer need to be made a no load for full series at 10
Modified values are a 250KC reverse audio pot for the Broadcaster blend, the 15k is left out like the original so full parallel could be achieved when turning it up, but also have the full Broadcaster like sound with blending the neck to the bridge, especially with no tone.
Then for the Series wafer, modified would be 100k audio.
