Blender pot behaviour

[andyg_prs]

Hi,

I've wired my Strat like this.

I would expect in positions 1 and 5 with the blender pot on full mix to have the same sound.

However with the neck pickup selected and no blend I go from a very warm sound to quite a trebly sound as you would expect blending in the bridge.

In the bridge position, regardless of what I do with the blender pot, there is virtually no change to the sound....

How can that be?

Regards,
Andy

Did you remember to swap out the stock audio taper pot to a linear taper pot?

^ I actually have a 250k no load audio taper pot as my blender. It only takes until about 8 until I fully hear the other pup being blended in. But it still works properly. Maybe it's possible that Andy's blender is actually not a no load... I dunno. Cuz if it's not a no load it always sounds like both pups are on.

It is a CTS 250k audio, no load pot...

Just a guess as I'm not sure exactly what you are designing but it looks like you want to do the Spin-O-Split with the bridge and neck to make a variable humbucker.

If this is true then you need to play with the coil polarities and the magnet polarities to get a humbucker. Do some research on "what makes a humbucker".

That harsh treble sound is the anti-humbucker side. I.e. The stuff a humbucker throws away.

If not then more info is needed as to what you want to do, info about magnetic polarities of each coil. Or if any are reverse wound.

Hi, your description makes sense. Everything is a bit hard to judge as I am just very disappointed with the output of the bridge single coil even before I try blending with the neck.

However, regardless, I just cannot fathom the logic of the neck pickup (position 1) going smoothly from its sound when the blender pot is in its "no load" position....to the extra treble when the bridge is blended in.....yet the bridge being trebly when selected (position 5) but the blend not seeming to add in the neck.

I know everyone thinks they know what they are doing...but I've done some quite complex wiring.....and simple taking a wire off the bridge and neck lugs on the 5-way switch to a blender pot is so simple....I cannot see how I have possibly done anything wrong...

Cheers,
Andy

Re: Blender pot behaviour

In your pic. The coils are parallel and the magnets are probably in parallel (both N up). For a humbucker one coil needs to have reverse electrical polarity and each coil needs opposite magnetic polarities. One N up one N down

When you rest a while (sometimes you need to push away or sleep on it) and absorb this ,try physically swapping the middle pickup to the bridge position, reconnect it as a bridge pickup and see if it gets you closer to what you want. (The middle pickup is RWRP and opposite magnetic polarity. That is if this guitar started out as a 5 position Strat that hum cancelled in 2 and 4 positions. But also know that you 2 and 4 positions might need tweaking
