3-way switch vs. blend knob

Blend knob or 3-way switch?

  • Definitely a blend knob. Why limit yourself to only three options?

  • Probably a blend knob. You're rarely going to touch it anyway, right?

Recently got a jazz bass after being a single pickup player. The blending with VVT are pretty cool, but I'm to used to having a single volume knob. I rewired to a passive blend knob and found it had the often reported issue of darker overall tone (an extra pot), and also being worse at getting the intermediate tones (I followed the standard advice on proper taper). I since have rewired to a 5 way rotary. Positions 1/3/5 are the standard neck/dual/bridge. 2 and 4 are Neck on/ bridge 90% and bridge on/neck 90%, following the example of the fender Roscoe beck wiring (adding a resistor in series with the pickup to turn down, resistance about 10% of volume pot value). To me this feels pretty good, but a 3 way switch also would be fine for me. Fwiw, I also have a push pull series switch on the volume, and the tone is a TBX circuit. Ill probably change the tbx back to a normal tone pot at some point...
 
Ultrahsort version of the story: Should I get a 3-way switch or a blend knob?

Longer version:
It's time to change my Yamaha BB's. Most of them have Volume-Volume-Tone (which I absolutely despise).
I'm going to change to Master Volume, Tone, and.....something else.

I've come to the conclusion that my favorite pickup configuration is a P/J.
And 95% of the time, I use both pickups on full. The only time I ever change is when I'm getting a buzz or hiss from the jazz pickup, then I switch to "full P".

Since this seems to be a binary choice, should I just change to 3-way switch? Or have a blend knob?
Is there much sonic difference between the two? Is there a significant advantage to having one or the other?

The main disadvantage to a blend knob--it "confuses" me when I look down at it, and wonder "which is which? And which way do I turn the knob?" Maybe I'm just stupider than average, but I like the super-duper simplicity of the 3-way switch.
Man, I have totally been here and the three-way switch is awesome. I found that I only really ever wanted P by itself or PJ.

The switch has the guarantee that you're not loading down the P pick up with anything from the jazz - it's electrically a normal P bass setup. I found it actually sounded better after I put the switch in than with the blend because you're not trying to compensate for the extra pot in line.

Also it really simplifies your decision-making when playing. You either want P or PJ or J - no fiddling about pretending that the blend does anything 😆
 
I enjoy a three way...

...although a five way is better ;)

A blend pot for me.

For me, a big part of adjusting tone is simply adjusting that blend and moving my picking hand closer to the bridge or neck.

Two volumes, I get the blend just like I want, but I can't turn up or down without changing it.

I lived with 3-way switches for years on my 80's BB's, and while I could do business with it, I always wanted a blend pot instead.
