    Would you wonderful folks know where a wiring pleb could find a way to blend my pickups with both tone knobs? I don't typically mess with the tone knobs, so I'd like to convert the two knobs to two separate blend knobs. Any help and advice would be welcome!

    I think we need clarification. What exactly are you trying to accomplish with the blend knobs: Pickup selection instead of the 5 way switch, and if so what pup combos, or are you trying to do something else?

    See, I was under the assumption that you could turn the tone knobs into a blend knob for different positions of the switch. Say, Position !(or 5, for the neck only pup) and the tone knob could blend in like say the bridge pup little by littl to color the sound.

    The blend wiring on my S style is master tone & the other is the blend.

    Didi you have to add a different blend specific pot to the set up? Or did you just use the original tone knob?

    I don't have a blender circuit, but that's the one that I think I've settled on for a Strat build I'm doing right now. So I've been reading a bit about this stuff, but far from what I'd consider "informed" on the topic. A regular potentiometer is, as you know, a variable resistance mechanism. When it's set on "1" it is giving the maximum resistance that it's capable of giving, when it's set on "10" its giving the minimum resistance (note, minimum is not the same as no resistance). So a no load pot just puts a notch at the end of the wiper contact point so that settings 1-9 offers some level of resistance, but at 10, the pot becomes bypassed in the circuit and is offering no resistance at all, thus "no load." When you measure one with a VM you notice you get a max resistance measurement at one end, then the number continues to drop and drop and drop until you reach the notch when you get "UL" or infinite.

    A blender circuit starts with the proposition that you want Pickup A to send a signal to an amp, but you'd like the option of sprinkling a bit of Pickup B to flavor that signal. Right away you need the ability to turn Pickup B off and on. That's what the no load pot allows you to do.

    So I assume in this case when you bypass the blender pot completely you are using only the selected pickup, Pickup A. When you want to add another pickup to the sound, you do so gradually by turning the blender knob until the signal from that pickup is to your taste, like a dimmer switch. If you only want the bridge pickup, say, then you'd turn the influence of the blender pot off by bypassing the contribution of Pickup B completely. That's sorta my understanding of it all, and believe me, I don't understand it.

    I had it installed when I ordered the guitar. I believe that it requires a different type of pot. A regular tone pot won't work, if I remember correctly.

    I plan to do this mod to one of my strats. Too good to pass up. ToneShaper makes a mod kit that includes everything for a complete re-wire that I think I'm going to get. Except I don't like treble bleed circuits which is included. So I'll just not use that. If ya'll want to check out the kit, I will attempt to attach a link. Platefire
