And it looks like you got the strings alinged perfectly over the polepieces!

I don't know if you want to go there, but if you buffer the pickups before blending them, a lot of the issues with loading (and weird comb filtering) can go away. I'm a big fan of an active blend.

What is buffering?
Putting a preamp right after the pickups. Back in the day Phil Lesh had preamps built right on the bottom of the BiSonic pickups themselves, affectionally known as "spider sex" preamps.

A buffer is essentially a preamp without gain that electronically separates the pickup from all of the following passive parts. Because a pickup is a coil and pot is a (variable) resistor, adjusting the volume on a passive bass can change the tone when the volume is changed. Add a second pickup and the whole thing becomes an interactive circuit where the sound changes with the volume pots (or blend pot, if you have one in there). Add in a cable and the resistance and capacitance of the cable adds its own flavor. With a buffer, the tone of the pickup remains constant. Some people think that's a good thing and others like the passive sound. Personally, just about all my basses have buffers (aka active electronics), mostly with active blends, which is simply placing the buffers or preamps before the blend pots (which requires two preamps).

Some basses combine the pickups prior to the preamp and if there are pots involved, you lose the benefit of an active buffer, so the pickups still interact with each other.

You are correct about loading issues - but not w comb filter effects. They are caused by the fact that two pups are involved.

That seems like it would be the case, but I've had the weird sound when the passive blend pot is dead center go away when switching to an active blend. I was addressing the earlier post and using that terminology, so perhaps comb filter is the wrong description.

W passive blend you enter the complex total impedance, that both pups see - like you described - and there could well be resonating frequencies here and there - and they vary, when you tweak the knobs - any of them.

Amazing commentary. Wow.

It's a great reminder. I'm about to dive back into synth world for a little while. The warming is "don't get obsessed with finding that perfect sound. Just finish the damn song.

I have 4 usable tones now with my blend knob x 16 Tonestyler settings each. But I still like true bypass on the neck pup best.

Thank you for sharing your journey with this bass!
